Abstract

In this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using dried (BD) SARGASSUM SP. (brown marine ALGAE) and ACTIVATED CARBON (AC) prepared from it was examined. Biomass, pH and the initial concentration of Cr (VI), ADSORPTION models and kinetic studies were investigated. The experiment was performed in a batch system and the effect of solution pH, initial concentration and contact time on biosorption by both biomasses were investigated and compared. When we used AC and BD as BIOSORBENTs, optima conditions were established at pH=2.0, Cr6+ concentration at 3.69 mg/g BD and 6.877 mg/g AC and equilibrium time of 120 min.The ADSORPTION was in the range of 83.55% and 91.98%, respectively. The experimental ADSORPTION data were fitted to the Langmuir ADSORPTION model.The chromium (VI) uptake by the BIOSORBENTs was best described by a pseudo second-order rate model.
