  The characterisation of biosorption by Schizosaccharomyces pombe of Co(II) was done under varying experimental conditions including pH, temperature, initial metal concentration and biosorbent dose. Optimum pH was found to be 5.0 with optimal biosorbent dose for highest adsorption capacity at 1.0 g L-1. Higher initial metal concentrations helped enhance qe slightly with the highest value, 2.7 mg g-1, being achieved at 25°C and 50 mg L-1 initial Co(II). Temkin isotherm model showed the best statistical fit for equilibrium data while Freundlich isotherm model exhibited thermodynamic consistency. Pseudo-first order kinetics was found to represent Co(II) biosorption. Increasing ΔG0 values calculated with respect to higher operational temperatures were in agreement with kinetic profiling simulations whereby higher tem.. Read More»
