Rational design of biomaterial functionalized grapheme magnetite nanobioconstruct as multifunctional material for wastewater treatment

Abstract

Discharge of toxic pollutants containing wastewater into water newlinebodies continuously deteriorates the freshwater quality and causes serious newlinedamage to both environment and human life. as a consequence, considerable newlineattention has been devoted for development of efficient waste treatment newlinetechnology for removal of toxic pollutants. owing to the unique newlinephysicochemical properties, the nanomaterials exhibit excellent newlinedecontamination performance compared to the classical wastewater treatment newlinemethods. especially graphene oxide (go) nanosheets received a great interest newlinedue to its unique physicochemical properties such as large surface area newline(2630 m2/g), high intrinsic tensile strength (130.5 gpa), high electrical newlineconductivity (6500 s/m), low thermal conductivity (0.5 1 w/m/k), excellent newlinestability in acid and alkali and biocompatible. graphene is widely used in newlinedevelopment of novel, cost effective, and sustainable technology in the newlinedecontamination of water from dyes, heavy metals, oils, and pathogenic newlinemicroorganisms. however, difficulty in removal of anionic toxic contaminants, newlineseparation of go after treatment, ecotoxicological issues caused leaching of newlinegraphene are major problems. in chapter 1, the biological materials newlinefunctionalized graphene based nanocomposites are prepared and used for newlinedecontamination process with a detailed focused on its removal efficacy, newlineadsorption capacity, mechanical stability, adsorption mechanism, and newlinerecyclability process. in chapter 2 presented the experimental protocol. newlinedespite of immense application potential of graphene in wastewater newlinetreatment, the colloidal stability, aggregation and recyclability remains a major newlinechallenge. to address this issue (chapter 3) the biomaterial functionalized newlinegraphene magnetite (bio gm) nanocomposite was fabricated as a novel newlinerecyclable material for treatment of wastewater containing dyes and heavy newlinemetal. newline newline
