Abstract

In this study, the biosorption of lead (II) ions on Sargassum ilicifolium, brown seaweed, was investigated in a batch system. The effects of operating parameters such as initial pH, initial metal ion concentration, and biosorbent concentration on the lead (II) biosorption were studied using response surface methodology (RSM). The optimum biosorption conditions were determined as initial pH 3.7, biosorbent concentration 0.2 g l1, and initial lead (II) ion concentration 200 mg l1. The maximum uptake capacity of S. ilicifolium for lead (II) ions was found to be 195 ± 3.3 mg g1 at optimum conditions. The nature of biomassemetal ion interactions was evaluated by FTIR analysis. The equilibrium biosorption data fit very well with both Langmuir and Freundlich isotherm models. The biosorption performance of S. ilicifolium for lead (II) ions (qmax ¼ 195 mg g1) was significantly higher than the Pb(II) biosorption performance reported for other biosorbents. The abundant and economic biomass S. ilicifolium could be used for removal of Pb(II) from wastewater.
