The salicylic acid-formaldehyde condensed copolymer (SAF) and the 3-carboxy-4-hydroxy benzyl methacrylate divinylbenzene copolymer (CHBM-DVB) were synthesized. The capacities of SAF and CHBM-DVB ion exchangers were 4.6meq/g and 3.9 meq/g, respectively. The adsorption of several heavy metal ions on these weakly acidic ion exchangers and the property of ion exchanger were discussed. The distribution coefficients in hydrochloric acid solution and the elution behavior of several heavy metal ions were also discussed.
