Abstract

Heavy metals are ubiquitous environmental contaminants in industrialized societies. The presence of heavy metals in the environment is of major concern because of their toxicity, bio-accumulating tendency, threat to human life and the environment. Traditional methods have been used to remove heavy metals from effluent include chemical precipitation, chemical oxidation/reduction, ion exchange, electrochemical treatment, evaporation and filtration. Many of these methods are ineffective; resulting in low levels of metal ion removal and can also be economically inefficient. Biomass of brown marine macro algae is a renewable biological resource, which is available in large quantities and can form a good base for the development of biosorbent material. The work considered the parameters of the effluents and the experimental column model for the metal adsorption. Among the experimental model Thomas model fitted the column biosorption data well.
