Their properties of the prepared nanocomposites were analysed using XRD, FT-IR, FE-SEM, EDX, DRS and PL tests. The DRS and PL results confirmed a narrow band-gap energy and low recombination rate of photo-produced electron and hole pairs, respectively. The effect of adding various dopant agents (urea and L-asparagine) with different loadings and magnetic nanoparticle (ZnFe2O4) into TiO2 sol on the photodegradation of DR16 was also evaluated. As a result, the L-asparagine (2 wt. %)–TiO2/ZnFe2O4 is the best photocatalyst compared to the other modified TiO2 nanocomposites due to its narrow band gap and high quantum efficiency. The catalyst concentration (1–2 g/L), DR16 concentration (25–45 ppm), initial pH (4–10), and irradiation time (30–90 min) as numerical variables were also considered for photocatalytic process analysis and moulding by central composite design (CCD). The increase in the pH and dye concentration reduces the photodegradation efficiency while irradiation time and catalyst concentration effectively improved its photodegradation efficiency. The DR16 was completely removed at 25 ppm of DR16, initial pH of 4 and 1.5 g/L of photocatalyst after 90-min irradiation. The photoactivity test was also repeated four times by reused L-asparagine–TiO2/ZnFe2O4 photocatalyst at optimum conditions. The decrease of dye degradation and loss of photocatalyst were not significant which was approved by the good performance and high recovery capability of the prepared nanocomposite.

The process analysis was performed by varying four significant independent variables including two numerical factors (initial pH (3–11) and initial H2O2 concentration (0–20 mM)) and two categorical factors (UV irradiation and ozonation). The experiments were conducted based on a central composite design (CCD) and analyzed using response surface methodology (RSM). To assess the process performance, two parameters viz. TCOD removal efficiency and BOD5/COD were measured throughout the experiments. A maximum reduction in TCOD was 58, 53, 51, and 49%, respectively for UV/H2O2/O3, H2O2/O3, UV/O3 and UV/H2O2 processes at the optimum conditions (initial pH of 7, initial H2O2 concentration of 100 mM, and reaction time of 180 min). A considerable increase in BOD5/COD ratio was obtained in the combined processes (0.46, 0.51, 0.53, and 0.55 for UV/H2O2, UV/O3, H2O2/O3 and UV/H2O2/O3, respectively) compared to the single oxidant process (0.35). The results showed that mineralization of the LAB industrial wastewater in neutral pH is more favored than in acidic and basic pH. Gas chromatography–mass spectrometry (GC–MS) was applied to show the fate of organic compounds. In conclusion, the photooxidation process (UV/H2O2/O3, H2O2/O3, UV/O3 and UV/H2O2) could be an appropriate pretreatment method prior to a biological treatment process.

The synthetic polymer was characterized via Fourier-transform infrared (FT-IR) spectroscopy, surface area and porosity analysis, and X-ray diffraction (XRD). Static adsorption experiments were conducted to evaluate the adsorption kinetics, adsorption isotherms and adsorption selectivity of MIP/K 2 Ti 6 O 13. Adsorption kinetic studies revealed that a contact time of 300 min was necessary to attain equilibrium. Adsorption isotherm studies indicated that the capacity of MIP/K 2 Ti 6 O 13 towards the adsorption of DBT at 298 K, 308 K and 318 K was 16.18 mg/g, 22.74 mg/g and 29.89 mg/g, respectively. Selectivity experiments showed that the adsorption capacity of DBT on MIP/K 2 Ti 6 O 13 was greater than for the other three analogues, while the imprinting factor towards DBT (α) was 2.06.

Using a kinetic study and degradation efficiency test, these visible driven photocatalysts were investigated for their photocatalytic activity in removing antibiotics, including metronidazole (MNZ) and cephalexin (CEX). The morphology, structure and optical properties of the fabricated catalysts were characterized by X-ray Powder Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectrometry (EDS)/mapping, Fourier-Transform Infrared Spectroscopy (FTIR), Photoluminescence Spectroscopy (PL) and UV-Vis Diffuse Reflectance Spectroscopy (DRS) analyses. Based on the results of the PL analysis, it was confirmed that doping TiO2 with amino acids containing C, N, and S inhibited the recombination of induced electrons and holes. Among the three cata...

B-ZnO/TiO2 was synthesized by the sol-gel method and the composite with 5 wt. % of B and 0.5 wt. % of ZnO was selected as the optimal composition, based on DR16 removal experiments. Th results showed that the removal efficiencies for optimum amounts of B and ZnO were 47 and 87 % in B-TiO2 and B-ZnO/TiO2 composition, respectively. The structural and chemical characteristics, modeling and optimization of the operating variables, adsorptive behavior, and reusability of the synthesized photocatalyst were evaluated. The acquired findings confirmed the generation of an amorphous phase with a low recombination rate and an improvement of photodegradation efficiency under visible light irradiation. The effects of (NH4)2S2O8, H2O2, KCl, and KHCO3 salts on dye photocatalytic ...

Three novel visible-light-responsive nanostructures, including L-Histidine-TiO2, L-Methionine-TiO2 and L-Asparagine-TiO2, were successfully synthesized. The results showed that the modification of TiO2 with these three amino acids made the catalyst active in the visible light region and reduced the recombination rate of e−/h+ pairs according to PL analysis. The photodegradation efficiency of L-Histidine (2 wt.%)-TiO2 was 100% and 94% for OTC and COD, respectively. It showed the highest photocatalytic activity under illumination, compared to L-Methionine (1.5 wt.%)-TiO2 and L-Asparagine (2 wt.%)-TiO2. Synthesized composites were characterized with SEM, XRD, FTIR, DRS, and PL analyses. The biological oxygen demand to COD (BOD5/COD) ratio for tre...

The physical and chemical characteristics of prepared activated carbon have been investigated using scanning electron microscopy, Brunauer-Emmett-Teller, Fourier-transform infrared spectroscopy, and pH of zero point charge (pH ZPC). Then, the application of the prepared corn stalk activated carbon was investigated to remove the Methylene Blue (MB) dye from aqueous solution. The effect of four independent factors including initial concentration (10-210 mg L-1), adsorbent dosage (0.2-1.4 g L-1), pH (3-11), and contact time (10-50) were also evaluated by response surface methodology at five levels. Complete dye removal was observed at an initial concentration of 10 mg L-1 , and adsorbent dosage of 1.4 g, pH of 11, and contact time of 50 min. The adsorption kinetics was also described by the pseudo-second-order model with R 2 = 0. 9833. The results of comparison equilibrium data between Langmuir and Freundlich models showed that the adsorption process was best described by Freundlich with the maximum adsorption capacity q m = 2.34 mg g-1. The experimental data were also fitted with Freundlich isotherm (R 2 = 0.91). Base on the results, it can be concluded that corn stalk activated carbon produced from agricultural wastes is a highly promising nontoxic and environmentally friendly adsorbent with great potential for removing of MB.
