6-Mercapto purinylazo resin has been used as solid phase extractor. Based on solid phase extraction, the present work describes the preconcentration and determination of copper, zinc and cadmium in certified biological samples after microwave-assisted digestion. The exchange capacity of the resin, the sorption and desorption of metal ions, and the effect of diverse ions have also been determined. The results show that the resin is highly selective for determination of these biologically significant metals. The method is simple, rapid and free from interferences and can be used routinely.
6-巯基嘌呤偶氮树脂已被用作固相萃取剂。基于固相萃取，本研究描述了微波辅助消解后对有证生物样品中铜、锌和镉的预富集与测定。还测定了树脂的交换容量、金属离子的吸附和解吸以及不同离子的影响。结果表明，该树脂对测定这些具有生物学意义的金属具有高度选择性。该方法简单、快速且无干扰，可常规使用。
