Solvent-impregnated resins (SIR) containing Cyanex 302 (bis [2,4,4-trimethylpentyl] monothiophosphinic acid) have been prepared using Amberlite XAD-2, XAD-4, XAD-7 and XAD-8 as polymeric support. These prepared SIR have been used for the extraction of Cd(II) and Cu(II) from phosphoric acid solutions. The effect of phosphoric acid concentration on Cd(II) uptake has been investigated by batch extraction method. Columnar extractions of Cd(II) and Cu(II) from 40% H3PO4 have been performed using XAD-7 resin impregnated with Cyanex 302. The resin exhibited similar column sorption behaviour for both Cd(II) and Cu(LI). The elution of both Cd(II) and Cu(II) from SIR has been achieved with 4 M HCl solution. The elution of Cd(II) occurred sharply but with a long tail-off and furthermore the elution of Cu(II) was slow.
