Abstract

Pollution of water bodies by heavy metals is the outcome of manmade factors that caters to the need of growing population. Heavy metals are a major source of pollutants which are highly sensitive to human and aquatic livings. Though they are present in relatively smaller quantities than the other class of pollutants, they pose severe threats. Hence removal of heavy metals to the desired level is an important field of research. In this context, an attempt has been made to study the potential of the marine algae Sargassum tennerrimmum in recovering cobalt ions and also to study the sorption kinetics using three kinetic models. In addition to this, isotherm modelling studies were made using three models. The outcome of the modelling shows that the Lagargren first order kinetic model and Langmuir isotherm model were able to fit the kinetic and equilibrium uptakes respectively.
