Chemical Spectromatric Determination of Enriching Trace Amount of Ir,Mo,Ni in Waste Water by Using Chelating Fiber

本文建立了利用带有酰胺肟—羧基功能团的螯合型纤维富集废水中铱、钼、镍痕量元素的化学光谱法.探讨了螯合纤维富集待测元素的最佳条件及共存离子 Fe^(3+)、Al^(3+)、Ca^(2+)、Mg^(2+)、Cu(2+)、Zn(2+)和 Cr_2O_7^(2-)对待测离子的富集效果影响,并测定了废水样中各待测痕量元素,获得了满意结果.方法具有快速、灵敏的特点.

In this paper,the chemical spectrometric method of enriching and de-termining trace amount of Ir,Mo,Ni in waste water by means of chelati-ng fiber with lamide oxime-carboxylic group has been established.Theoptimum condition of enriching the elements with chelating fiber and theeffect of co-existent Fe^(3+),AP^(3+),Ca^(2+),Mg^(2+),Cu^(2+),Zn^(2+),Cr_2O_7^(2-) ionson the enriched results of Ir,Mo,Ni have been investigated.The traceamount of Ir,Mo,Ni in waste water have been determined with satisfa-ctory results.This method displays the charactristics of quickness and se-nsibility.
