RESUMO

This study focused on the batch removal of Cu2+ ions from an aqueous solution and wastewater using marine brown algae Sargassum angustifolium. Desorption experiments indicated that CH3COOH and EDTA were efficient desorbents for recovery from Cu2+. With high capacities of metal biosorption and desorption, the biomass of S. angustifolium is promising as a cost-effective biosorbent for the removal of Cu2+ from wastewater. According to X-ray photoelectron spectroscopic and Fourier transform infrared spectroscopic analysis; the possible organic functional groups in the metal binding include carboxyl, amino, sulfhydryl and sulfonate groups. The point of zero net proton charge was found close to pH 6.1. The biosorption of Cu2+ ions and effect of pH was studied. Langmuir, isotherm model were applied to describe the biosorption of the Cu2+ onto Sargassum biomass. According to result biomass of S. angustifolium could be used as an effective biosorbent for the treatment of Cu2+ containing wastewater streams. i
