High concentration of heavy metals (such as cobalt) can create serious environmental problems through pollution of the aquatic environment and subsequent magnification, accumulation and transfer to other components of the environment. In attempt to search for ecofriendly approach aimed at reducing concentration of cobalt in contaminated water. The effectiveness of chitosan for the removal of cobalt ion from aqueous solution was investigated with reference to concentration, period of contact and through the measurement absorbance before and after adsorption. We observed that chitosan has good adsorption surface for cobalt ion and the adsorption was facilitated through the N-H and C-O functional groups in the chitosan.
