Therefore, it is essential to treat industrial wastewater containing these heavy metals before being discharged into the environment. In this study, we evaluated the sorption of Pb 2+ , Cd 2+ , and Zn 2+ metal ions onto Thaumatococcus danielli. We studied the effects of different influential parameters such as contact time, pH, metal ion concentrations, and temperature. The batch sorption study revealed that the sorption process is pH dependent, with optimum pH obtained at 4.0 for Pb 2+ and Cd 2+ and 5.0 for Zn 2+ , respectively. The sorption equilibrium and kinetic rates studied revealed that the adsorption data best fit Freundlich isotherm and pseudo-second-order models, respectively. The q max values obtained are 95.215, 77.482 and 84.090 mg/g for Pb 2+ , Zn 2+ and Cd 2+ , respectively. Thermodynamics analyses indicate that the metal ions sorption on Thaumatococcus danielli is feasible, spontaneous, and endothermic. The enthalpy values are 61.42, 42.17, and 41.34 kJ/ mol for Pb 2+ , Cd 2+ and Zn 2+ , respectively. Fourier-transform infrared analysis showed ionizable functional groups such as-OH, C=C, C≡C, C=O, CO , and C-H, which could involve the metal binding. The results indicated that Thaumatococcus danielli could be a prospective sorbent for the sorption of Pb 2+ , Cd 2+ , and Zn 2+ from polluted aqueous solution.

The FTIR spectra characteristics of Manihot esculenta leaf revealed the presence of ionizable groups that could participate in the binding of metal ions in solution. The biosorption of each of the ions was found to be dependent on the physicochemical parameters such as solution pH, contact time, initial metal ion concentrations, biosorbent dose, and temperature. The biosorption kinetics follows a pseudo-second- order kinetic model with biosorption rate of the order Pb(II)>Cd(II)>Zn(II). The biosorption capacity was found to be of the order Pb(II)> Zn(II)>Cd(II). Equilibrium isotherm studies showed that the biosorption followed the Freundlich isotherm model, which implies a heterogeneous sorption phenomenon. Thermodynamic parameters such as changes in free energy, enthalpy, and entropy have been calculated. The negativ...

Optimisation studies were carried out using batch biosorption studies. The extent of the metal ion biosorption increased with increase in solution pH, initial metal ion concentration, dosage of biosorbent and contact time but decreased with the temperature of the system. The biosorption of each of the metal ions was found to be pH-dependent. Kinetic study showed that the metal ions biosorption process followed the pseudo-second-order kinetic model. The sorption of each metal ion was analysed with Freundlich and Langmuir isotherm models, in each case, the equilibrium data were better represented by Freundlich isotherm model. Thermodynamically, parameters such as standard Gibbs free energy (ΔG˚), standard enthalpy (ΔH˚), standard entropy (ΔS˚) and the activation energy (A) were calculated. The ...

The effects of pH, contact time and initial metal ion concentration on the biosorption were monitored. The residual Cd(II) in solution was determined using atomic absorption spectrophotometer. The biosorption was found to be pH-dependent and the optimum pH for the biosorption was pH 3. The biosorption was also time-dependent as maximum biosorption was obtained after 2 h. The Freundlich equation obtained for the biosorption was log = 0.8775 log C e + 1.095 while the Langmuir equation was 1 / = 0.0982/C e-0.0058. The correlation factors were 0.9943 and 0.9869, respectively. The removal efficiency decreases with increase in initial Cd(II) concentration due to reduction in available binding site on the biosorbent for Cd (II). The free energy change for the biosorption at 300 K with an initial Cd(II) concentration of 100 mgL-1 and pH 3 was-7.17 kJmol-1. These results indicate that maize leaf has potential for the uptake of Cd(II) from industrial effluents.

Optimisation studies were carried out using batch biosorption studies. The biosorption of each of the metal ions was found to be pH-dependent. Kinetic study showed that each biosorption process followed the pseudo-second-order kinetic model. The sorption of each metal ion was analysed with Freundlich, Langmuir, Temkin and Dubinin-Radushkevich (D-R) isotherm models, in each case, the equilibrium data were best represented by Freundlich isotherm model. Thermodynamic parameters such as standard Gibbs free energy (ΔG˚), standard enthalpy (ΔH˚), standard entropy (ΔS˚) and the activation energy (A) were calculated. The biosorption of each metal ion was spontaneous and the order of spontaneity of the biosorption process being Zn(II) > Cd(II) > Pb(II).
