Abstract

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.

SAF 축합중합체와 CHBM-DVB 공중합체를 합성하였다. 이들 합성된 이온교환체의 이온교환용량은 각각, 4.6meq/g and 3.9 meq/g이었다. 또한 이들 약산성 이온교환체에 대한 몇가지 금속이온들의 흡착능과 이온교환체 성질에 대하여 논의하였다. 그리고 이온들의 염산용액중에서의 분포계수와 몇가지 용리현상에 대하여 논의하였다.
