Abstract

The present work examined the efficacy of designed Mg(OH)(2) nano-platelet assembly (DMGHNPA) for toxic Cu(II) waste removal from water. For this purpose, DMGHNPA with surface area as high as 237 m(2).g(-1) was synthesized by a very simple and cost effective method at room temperature. The results showed that at concentration range of 80-1000 mg.l(-1), extra-ordinarily high e.g. > 99% Cu(II) ion adsorption efficacy was achieved by the DMGHNPA. Based on the experimental data, adsorption mechanism is proposed to explain the extra-ordinary high adsorption efficacy of the DMGHNPA. The efficient adsorption was occurred through Cu-2(NO3)(OH)(3) microspheres formation on the surfaces of self-supported DMGHNPA. The implication of such extra-ordinary high adsorption efficacy of the Mg(OH)(2) nano-platelet assembly is discussed further in the context of toxic waste e.g. Cu(II) ion removal from water.
