CHITOSAN ASSISTED SYNTHESIS OF MULTI-LAYERED ZINC CARBONATE HYDROXIDES FOR MASSIVE REMOVAL OF CU2+ FROM WATER

ABSTRACT In this paper, the zinc carbonate hydroxide (Zn5(OH) 6(CO2)2, ZCHO) was prepared by a facile hydrothermal method assisted chitosan (CS). The as-prepared product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TG). Results indi...
