dc.description.abstractAdsorption of Cu (II) from aqueous solution by crab-shell derived chitosan was evaluated and optimised by response surface methodology alongside comparison with commercial chitosan. The commercial and locally developed chitosan was found effective in removal of copper (II) ion from aqueous solution and the results of the copper ion percentage removal was 99.57% for locally produced chitosan and 99.80% for commercial chitosan at pH of 6.0. Optimum metal uptake (99.57%) was observed at pH 4.75, 120 minutes equilibration time and dosage of 2 g/50ml. The monolayer adsorption capacity of the commercial and locally developed chitosan was 1.44 mg/g and 1.49 mg/g respectively. The isotherms modelling indicated that the Langmuir isotherm was the best fit. The kinetics for the adsorption of copper, onto chitosan was best described by a pseudo-second-order kinetic model. It has been shown that chitosan are excellent precursors for the removal of copper from aqueous solution and consequently for its use in remediating polluted industrial effluents.en_US
