  • Abstract

    Sulphonated polyphenolic biocarbon was used to replace part of the weak acid cationic resin which was prepared from polycondensation of resorcinol and formaldehyde. A few composite ion exchangers were prepared by varying the amount of sulphonated Terminalia arjuna (Roxb.) carbon (STAC) in the blends from 10-50% (w/w) with the parent polymeric matrix. These composite resins were characterized by cation exchange capacity (CEC), % of gravimetric swelling, % of attritional breaking, FT-IR, TGA -DTA, SEM with EDAX studies. Scanning electron microscopy images used to compare the surface morphology of IERs (ion exchange resins) before and after ion exchange process for the removal of metal ions. Pb(II) ion selectively showed the maximum CEC. This low-cost resins up to 30% (w/w) blending of STAC with RFR (Resorcinol-Formaldehyde Resin) showed the similar properties of parent RFR and Terminalia arjuna is freely available plant material
