Synthesis, Characterization and Application of New Terpolymeric Resin

4-HAPHF terpolymeric resin has been prepared by condensation of 4-Hydroxy Acetophenone (4-HA), Phenyl Hydrazine(PH) 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 Cr(VI). The newly prepared terpolymer was characterized and its structural elucidation was confirmed by elemental analysis, TGA, XRD, FTIR 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-HAPHF doses have also been studied and reported. The adsorption data were found to fit well with the Langmuir model. The percent removal of Cr(VI) was found to be increased with increasing adsorbent doses from 1 to 4gm. and maximum efficacy was found at 4gm. At optimum conditions nearly 91% abatement of Cr(VI) has been noted using 4-HAPHF. The results revealed that the terpolymeric resin as adsorbent reported in this article is effective for removal of Cr(VI) from wastewater and thus can be successfully used for control of chromium pollution.
