REMOVAL OF CR(VI) BY STABILIZED SOLVENT IMPREGNATED RESIN (SIR) PREPARED BY USING A HYDROPHILIC POLYMER ADSORBENT AND ALIQUAT 336.

ABSTRACT The solvent impregnated resin (SIR) was prepared by using Diaion HP-2MG as a hydrophilic polymer adsorbent and commercial Aliquat 336 as extractant for hexavalent chromium Cr(VI) removal from aqueous solution. The resulting SIRs were stabilized by coating using poly(vinyl alcohol) (PVA) and...
