Heavy Metal Abetment Efficacy of New Terpolymer RPHF-II Derived From Resorcinol, phenyl hydrazine and Formaldehyde

All human being need fresh water for carrying out physiological, sociological, cultural and other activities. Unfortunately multifarious activity of human being for development and welfare lead to generation and release of objectionable material into the freshwater system which causes water pollution. Thus many areas of surface water and groundwater are now contaminated with heavy metals. Cr(VI) is highly soluble and reactive and considered to be acute toxic, carcinogenic and mutagenic to living organisms and hence more hazardous than other heavy metals. In the present work, a new terpolymer, RPHF-II was synthesized using resorcinol (R), phenyl hydrazine (PH) and formaldehyde (F). This copolymer was characterized using modern techniques like 1H-NMR, FTIR, XRD and SEM. The Cr(VI) adsorption was investigated using new terpolymer RPHF-II. Effect of pH, contact time, adsorbent dosage and initial Cr(VI) ion concentration was studied using batch experiments. The maximum removal of Cr(VI) was obtained to be 91% and optimal removal was favored at pH 5. The removal of Cr (VI) by terpolymer was found to be increasing with increase in contact time as well as with adsorption dose with stationary phase achieved at 150 min and 5.5 gm/lit respectively. The new terpolymer RPHF-II can be successfully used as an efficient material for removal of Cr(VI) from aqueous environments such as domestic and industrial effluents and can have a variety of potential environmental applications.
