Adsorption studies on toxic Cr (VI) removal using RSF-I Terpolymer

[摘要] The heavy metal, Cr (VI), is considered as one of the most toxic element to animals, plants, microorganisms and environment. Cr (VI) is non-biodegradable and accumulated in living tissues exerting its toxic effect thereby destabilizing ecosystems and even causing death of organisms. Therefore, it must be removed from contaminated water before discharge. The aim of the present study is an attempt to synthesize a new terpolymer with higher efficiency of Cr (VI) removal from aqueous solution. In the present study, a new terpolymer, RSF-I was synthesized using Resorcinol(R), Semicarbazine(S) and Formaldehyde(F). This terpolymer was characterized using modern techniques like 1H-NMR, FTIR, XRD and SEM. The Cr(VI) adsorption was investigated using new terpolymer, RSF-I, and 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 92% and optimal favored Ph was found to be 5. Thus new terpolymer, RSF-I, can be successfully used as an efficient adsorbent material for removal of Cr(VI) from aqueous media such as domestic and industrial effluents and can have a variety of potential environmental applications.
