The adsorption capacity of a cationic dye (Methylene blue, MB) from aqueous solution onto activated carbon prepared from sugarcane bagasse pith (Saccharum Officinarum) has been investigated. Activated carbon is prepared from sugarcane bagasse pith (SBP) using chemical activation method. This method involves impregnation with ferric chloride followed by carbonization. Activated carbon FAC-1, FAC-2 and FAC-3 are prepared from sugarcane bagasse pith using different impregnation ratios (SBP: FeCl3). It is found that adsorption of dye is influenced by several parameters such as initial dye concentration, contact time, solution pH, adsorbent dosage and adsorption temperature. Equilibrium adsorption isotherms and physico-chemical properties of the modified pith are investigated. Experimental adsorption data is correlated with Langmuir, Freundlich and Temkin isotherm models. Results of equilibrium experiments indicate that adsorption of methylene blue onto FAC-1, FAC-2 and FAC-3 is better d...

Bagasse pith, which is the main waste from sugarcane industry in Egypt, has been used as a raw material for the preparation of different activated carbons. Activated carbons were prepared from bagasse pith by chemical activation with 28% H 3 PO 4 (AC1), 50% ZnCl 2 (AC2) followed by pyrolysis at 600°C and by physical activation at 600°C in absence of air (AC3). Different activated carbons have been used for the removal of reactive orange (RO) dye from aqueous solutions. Batch adsorption experiments were performed as a function of initial dye concentration, contact time, adsorbent dose and pH. Adsorption data were modeled using the Langmuir and Freundlich adsorption isotherms. Adsorption kinetic data were tested using pseudo-first-order, pseudo-second-order and intraparticle diffusion models. Kinetic studies showed that the adsorption followed pseudo-second-order reaction with regard to the intraparticle diffusion rate.

The use of activated carbon made of sugarcane bagasse, to eliminate cationic dyes present in waste water was studied in this research. It investigates the potential use of activated carbon made of sugarcane bagasse. Increase in the PH of the dye solution caused an equivalent increment in its adsorption efficiency. This study demonstrates that activated carbon made from sugarcane bagasse is an efficient and cheap adsorbing agent and very effective at removing dyes present in solutions and the possibility of using it for a simple and inexpensive method of dye removal from waste waters in either stirred tank reactors or in batch reactors. The data obtained could be utilised to design an optimally productive system that uses either stirred tank reactors or batch reactors remove of cationic dyes from effluents industrial. This study predicts effect of activated carbon made from sugarcane bagasse on adsorption of cationic dyes.

Adsorbent materials for industrial and environmental applications are the goal of seeking research under active investigation now. Activated carbons could be obtained from the organic material after been chemically or physically treated. In Egypt, Sugarcane bagasse could be considered one of the agricultural wastes that frequently produced. In this study, the low-cost adsorbent was prepared from raw Bagasse. The batch experiment was set up to determine the effect of using the agriculture waste (sugarcane bagasse) without any modification and activated it chemically and physically on methylene blue removal. The influence of adsorbent amount, agitation rate, and temperature on the dye removal were studied. The result shows that the percentage of dye removal reached up to %99.6 when the initial dye concentration was 15 ppm, and the amount of sorbent (chemically activated) was 0.3 g at room temperature. The adsorption kinetics and isotherms for the removal of methylene blue were represe...

This study is investigated the potential of sugarcane bagasse, an agriculture waste as adsorbent for the removal of methyl orange dye from aqueous solution. Numerous research had been done in preparing low cost adsorbent from agricultural by-products. Activated carbon undoubtedly is the most prevailing adsorbent because of its high surface area adsorption capacity, and degree of surface reactivity. The activation process during preparation of activated carbon is normally been performed at high temperature (i.e. higher than 500 °C) and involved with a harsh chemical. This study investigated the potential of modified sugarcane bagasse with polyethylenimine (PEI) for removal of methyl orange (MO) dyes. The effect of PEI modified sugarcane bagasse adsorbent parameter on the efficiency of dyes removal including contact time, initial dye concentration, adsorbent dosage, temperature and pH have been investigated. The optimum result for MO dye removal achieve up to 82.0 % for parameters, co...

In this study, a novel activated carbon adsorbent from the press mud of a sugarcane industry was used to remove methyl orange dye (MOD) from aqueous solution and was optimized via response surface methodology using the central composite design. The adsorbent was characterized by FTIR and SEM analysis and showed the presence of functional groups such as alcohols, nitriles, amides, alkane, alkyl halides, and alkenes, and it also showed fibrous surface morphological appearance. The factors affecting MOD adsorption, such as initial concentration, adsorbent dose, and contact time were examined, and optimal pH 2.0 to remove MOD in an aqueous solution that is found in various studies is also utilized. The results showed maximum MOD removal rate of 98.68% when the initial concentration, adsorbent dose, and contact time were optimally set as 24.17 mg/L, 0.5 g, and 20 min, respectively. The analysis of the equilibrium data revealed that MOD adsorption using press mud activated carbon best fit...

Global Nest Journal, 2015
Low cost agricultural waste adsorbents can be viable alternatives to activated carbon for the treatment of contaminated wastewater. Sugarcane Bagasse, an abundant agriculture waste in Egypt, was used in the present study to prepare activated carbon. Batch adsorption experiments were conducted to study its effectiveness to remove cationic dye methylene blue from aqueous solution. The effects of initial dye concentrations, agitation time, solution pH and temperature on methylene blue dye removal were investigated. The optimum pH value for the maximum percentage removal of the dye was 7. Adsorption isotherms were determined and modeled with Redlich-Peterson, Langmuir and Freundlich equations at 20ºC.The kinetic data were analyzed using Pseudo-first order, pseudo-second order. The mechanism of the adsorption process was determined from the intraparticle diffusion model. Thermodynamic parameters such as standard enthalpy (ΔH°), standard entropy (ΔS°) and free energy (ΔG°) were determined. The equilibrium data were best fitted to the Redlich-Peterson isotherm model .The adsorption kinetics was found to follow the pseudo-second-order kinetic model with good correlation coefficient. The positive ΔH • value indicated that the adsorption process was endothermic in nature. The results revealed sugarcane bagasse activated carboncould be employed as a low-cost alternative adsorbent in wastewater treatment.
Adsorption isotherm and kinetics of methylene blue on activated carbon prepared from coconut husk were determined from batch tests. The effects of contact time (1–30 h), initial dye concentration (50–500 mg/l) and solution temperature (30–50 • C) were investigated. Equilibrium data were fitted to Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherm models. The equilibrium data were best represented by Langmuir isotherm model, showing maximum monolayer adsorption capacity of 434.78 mg/g. The kinetic data were fitted to pseudo-first-order, pseudo-second-order and intraparticle diffusion models, and was found to follow closely the pseudo-second-order kinetic model. Thermodynamic parameters such as standard enthalpy (H •), standard entropy (S •) and standard free energy (G •) were evaluated. The adsorption interaction was found to be exothermic in nature. Coconut husk-based activated carbon was shown to be a promising adsorbent for removal of methylene blue from aqueous solutions.
The incessant generation and discharge of large volume of textile effluent wastewater containing coloured dye solution mixture by textile industries into natural water bodies or rivers have been causing environmental pollution. The aim of this study is to use sugarcane bagasse activated carbon as adsorbent to treat textile effluent. Batch adsorption study was used to treat the textile effluent by optimizing dosage, concentration, contact time, and pH of effluent discharge to obtain optimum result. The untreated and treated textile effluent samples were analyzed using ultra violet (UV) spectrophotometer instrument to determine the concentration of the textile effluent solution. The results of the treatment of textile effluent analysis showed that the ash adsorbent had high percentage removal of the coloured dye in the solution. Optimization results of pH and contact time increase result in the increase of uptake capacity and removal efficiencies while increase in dosage and concentration increase, result in the decrease in uptake capacity and increase in removal efficiency which later decrease respectively. The isotherm study revealed that the Langmuir isotherm correlation coefficient R 2 = 0.985 is higher than the Freundlich isotherm correlation coefficient R 2 = 0.943. The isotherm adsorption data analyzed using Langmuir and Freundlich models are well fitted but the Langmuir isotherm is well fitted than the Freundlich isotherm, which indicate the fitness of the experiments. The fitness of Langmuir's model indicated the formation of monolayer coverage of the adsorbate on the outer surface of the adsorbent. In conclusion, bagasse activated carbon adsorbent was capable of adsorbing coloured textile effluent with high affinity and capacity which revealed its potential as a low cost alternative adsorbent.

Rice husk and sugarcane bagasse were chemically impregnated with ZnCl 2 and carbonized at 700 • C in a large-scale rotary furnace. The activated carbons (ACs) obtained had BET surface area of 811 and 864 m 2 /g, respectively, and were essentially microporous. The adsorption of arsenic, humic acid, phenol and a municipal solid waste landfill leachate was examined. Both ACs showed the best adsorption behaviour towards phenol, removing around 80% at the equilibrium time of 4 h. The adsorption isotherms for arsenic and humic acid were also favourable, although the maximum loadings achieved were lower than that of phenol. Finally, the rice husk AC showed 60% and 70% removal efficiency for colour and COD, respectively, when tested on a landfill leachate.
