dc.description.abstract	Removal of Cd(II) ions from aqueous solutions via adsorption using raw and acid-modified cassava tuber bark waste was investigated in a batch process. Effects of contact time, solution pH, temperature and initial Cd(II) ions concentrations on the sorption yield was evaluated. Optimum adsorption conditions were found to be pH of 5.5 and 5.0 for raw cassava tuber bark waste (RCTBW) and modified cassava tuber bark waste (MCTBW) respectively, initial Cd(II) ions concentration of 100 mg/L, temperature of 40 oC and contact time of 60 mins. The sorption process conformed Freundlich isotherm than the Langmuir isotherm. Kinetic studies showed that the uptake of Cd(II) ions by both adsorbents followed the Largergren pseudo-first-order kinetic model. FT-IR study showed the involvement of -OH, -NH, C=O, COOH and –C-N functional group in the sorption process. Thus, cassava tuber bark waste demonstrated excellent property as an adsorbent materials for the removal of Cd(II) ions from aqueous solutions.	en_US
