Title : Cellulosic Nanocomposites: Functional Vector For Arsenic Remediation

Author Name : Kiran Singh, TJM Sinha, Shalini Srivastava

Synopsis :

Surface Functionalization of Nanocrystalline Cellulose using Diethyl Amine was carried out to form an Anion Adsorbent (3-N-N' dimethylamino-2-hydroxypropyl Nanocrystalline Cellulose Ether) for Arsenic Remediation. The product was thoroughly characterized using modern tools. Nano-biosorbent had high efficiency of removal of trivalent (85.20 %) and pentavalent (97.60 %) arsenic from aqueous solutions, even at low concentrations. Adsorption capacity was found to be 8.28 and 9.56 mg/g for As (III) and As (V) respectively. Functionalized nano-biosorbent is ideally suited for economic biosorbent for pretreatment step before large scale chemical treatments for arsenic remediation.
