Biosorption is a cost effective process by using biomass raw materials which are either abundant or wastes from other industrial operations for decontamination of ionic pollutants, such as heavy metal ions. This work focused on the investigation of potential of "Polysiphonia nigrescens" biomass for removal of Cr(III) ions from aqueous solution. Experimental parameters affecting the sorption process such as pH, contact time, initial metal ion concentration and biomass dosage were studied. The equilibrium sorption data were evaluated by isotherm models. The experimental results were also analyze...
