The study of Sargassum capacity to adsorb Cr, Ni and Cu

Algae are a group of living things with very effective role in absorption and separation of heavy metals and are particularly economical in refining dilute wastewaters. Where as, application of live algae is very difficult in the industry, therefore their dead forms or material attracted from them are used. This study was made on sargassum algae (which is a macro algae from brown algae which is found in abundant amount in Persian Gulf) in continues system. In this article capacity of sargassum in heavy metals (Cr^3, Cu^2, and Ni^2) absorption has been studied. The evidences have showed that continues system of low flow rate can reduce the heavy metals concentration to levels as low as required by environmental legislation but in concentrate wastewater and high flow rate the remained heavy metals is high. The capacity of each gram of sargassum on this heavy metals absorption is about 5.15 mili mole and dried sargassum usage for heavy metals removing is more economical than lime usage or ion-exchange methods.
