Abstract In this study, adsorption of two cationic dyes, Toluidine Blue (TB) and Methyl violet 2B (MV 2B) from an aqueous solution was achieved by using multifunctional composite material.

The comonomer bisphenol A (BPA) finds applications in the plastics industry, where it is used production of polycarbonates, plastics, PVC, thermal paper, epoxy and vinyl ester resins, polyurethane. water, with which many these materials come into contact, one main sources human exposure to BPA. When ingested or touched, BPA can damage organs, disrupt endocrine immune systems, generate inflammatory responses, be involved genotoxic processes. Therefore, need develop effective techniques for removing from aqueous environments imperative. This paper provides a comprehensive review regarding removal focusing on performance adsorption mechanisms various adsorbents based chitosan composites. chemical physical factors, kinetics models governing process are also examined. outlines that, despite considerable progress absorption using gels, further research necessary assess efficacy treating real wastewater large-scale manufacture.
