Abstract:A calcium-alginate encapsulated BaSO4-APRB hybrid has been prepared. The SEM image illustrated sorbent has a calcium alginate polymeric shell and BaSO4-APRB cores. The adsorption selectivity and mechanism were studied by investigating the adsorption performance of two anionic and two cationic dyes. The adsorption of three cationic dyes (EV, MB and CR3R) from aqueous solutions was examined using a batch sorption technique. The effects of pH and ionic strength on the adsorption were examined. Besides, this material was applied in the treatment of two practical cationic dye wastewaters. Our study shows that the sorbent could be a potential candidate for utilization in dye wastewater treatment processes.
