Abstract

Heavy metal removal from industrial effluents has become a major concern. In the present investigation an attempt has been made to recover chromium from synthetic effluent using a marine algae Sargassum tennerrimmum. The pretreated algae was able to adsorb metal ions with greater efficiency. Among the three kinetic models chosen for study, Lagargren First order kinetics gave the best fit. The isotherm modeling study revealed that the Langmuir model is able to express the adsorption isotherm revealing monolayer sorption mechanism. It was also seen that the pretreated algae was able to achieve 87% metal recovery.
