Industrial wastewater contain higher quantities of salts besides chromium (VI) ions, therefore, the effect of these salts on the adsorption of chromium (VI) should be studied. In this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using two different activated carbon marine algae Gracilaria (red algae) and Sargassum sp. (brown algae) were examined. Activated carbon prepared from Gracilaria and Sargassum sp. The chromium uptake was dependent on the equilibrium pH and chromium concentration, with pH = 2.0, being the optimum pH value. The experimental adsorption data were fitted to the Langmuir and Freundlich adsorption …
