SYNTHESIS OF NOVEL TAMARIND 8-HYDROXYQUINOLINE-5-SULFONIC ACID (THQSA) RESIN AND THEIR APPLICATION IN INDUSTRIAL EFFLUENT TREATMENT
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2014, Vol 6, Issue 8
Abstract
Objective: An investigation was undertaken regarding the adsorption of different heavy metal ions from industrial effluent using novel tamarind 8-hydroxyquinoline-5-sulfonic acid (THQSA) resin.Methods: THQSA resin was synthesized by reacting epoxy propyl ether of tamarind with 8-hydroxyquinoline-5-sulfonic acid. The epoxy propyl ether of tamarind was synthesized by the reaction of epoxy chloropropane (epichlorohydrin) with tamarind kernel powder (TKP). The characterisation of the THQSA resin was carried out by FTIR (Fourier transform Infrared) spectra, elemental analysis and total ion exchange capacity. The effects of pH, treatment time, treatment temperature, resin quantity and flow rate on the removal of metal ions from industrial effluent were also studied.Results: THQSA resin proved to be an effective adsorbent for the removal of different heavy metal ions from industrial effluent; removal efficiency followed the order: Fe2+> Cu2+> Zn2+> Cd2+> Pb2+.Conclusion: These results suggest that the novel cation exchange resin THQSA holds great potential to remove cationic heavy metal ions from industrial effluent.Â
