摘要
An ICP-AES method using a new spherical macroporous epoxy-polyamide chelating resin to enrich and separate trace Ga(III), In(III), Bi(III), V(V), Cr(III), and Ti(IV) ions from solution samples is established. The results show that the analyzed ions can be enriched quantitatively by 0.1 g of the resin at pH 4, with recoveries > 98%. The ions can be desorbed quantitatively with 10 mL of 2M HCl from the resin column with recoveries > 96%, and 100-1000-fold excesses of Ca(II), Mg(II), Fe(III), Cu(II), Zn(II), AI(III), Ni(II), and Mn(II) cause little interference in the determination of these ions by ICP-AES. The chelating resin is reused for ten times; the recoveries of these ions are still over 95%. The relative standard deviations for enrichment and determination of 100 ng ml-1 Ga(III), In(III), and Bi(III), 10 ng ml-1 V(V), Cr(III), and Ti(IV) are in the range 0.6-2.3%. The concentration of each ion found in the real wastewater sample and alloy sample is in good agreement with the values provided by the plant. (c) 2005 Wiley Periodicals, Inc.
