Chitosan: a biopolymer: obtained by the deacetylation process of chitin, has intrinsic properties that make it an effective bioadsorbent for removing the heavy metal ions from wastewater. A method for the preparation of thiosemicarbazide-chitosan exploring the evaluation of enhanced adsorption of heavy metal ions and antibacterial activities via derivatization was proposed and experimented. The experimental equilibrium data was evaluated by the Langmuir, the Freundlich and the Dubinin-Radushkevich isotherm models. The applicability of the fit of model to experimental values was accessed on the basis of error analyses. The Langmuir adsorption model was hest titted with experimental value. suggests the existence of monolayer coverage of adsorbed molecules with a maxima of 142.85mg g'.
