Abstract

Heavy metals, which are a major class of water pollutants possess immense hazardous
effects on all the organisms consuming and living in water. Non degradable nature of these pollutants
need a technology to effectively recover the metals from water bodies for safer disposal. In the present
study the capacity of Sargassum tennerrimmum to recover arsenite and arsenate ions from synthetic
solutions were tested. Under optimum conditions the metal uptakes were found to be 80.833 mg/g and
76.7 mg/g for As (III) and As (V) respectively. Kinetic studies and isotherm studies using MATLAB
modeling showed that the Fractional Order Kinetics (compared to LFOK and PSOK) and Redlich
Peterson Isotherm (compared to Langmuir and Freundlich isotherm models) fit the kinetic and
isotherm data for both the oxidation state metals respectively with greater accuracy.
