Continuous biosorption of Cu and Zn by immobilized waste biomass Sargassum sp.
Biosorption of copper and zinc by the residual biomass of the alga Sargassum sp. was investigated in a mini packed-bed column. The biomass was immobilized in a polymeric matrix to improve its physicochemical properties for continuous biosorption of heavy metals from aqueous solutions. Adsorption bre...
