Abstract

A novel 4-HydroxyAcetophenone-Melamine-Formaldehyde(4-HAMF) terpolymeric resin has been prepared by condensation of 4-HydroxyAcetophenone(4-HA),Melamine(M) and Formaldehyde(F) in 1:1:2 molar ratio using 2M HCl as a catalyst and was proved to be a good adsorbent for removal of Cd(II). The characterization and the structural elucidation of the prepared terpolymer were confirmed by elemental analysis, FTIR, XRD, TGA and 1H-NMR spectral studies. The metal removal properties of the terpolymer were studied by batch equilibrium method. The effects of various parameters like contact time, initial adsorbate, concentration, pH and 4-HAMF doses have also been studied and reported. The adsorption data were found to fit well with the Langmuir and Freundlich isotherm models. At optimum condition nearly 94% abatement of Cd(II) has been noted using 4-HAMF. The results revealed that the terpolymeric resin as adsorbent reported in this article is effective for removal of Cd(II)from wastewater and thus can be successfully used for control of Cd pollution.
