ICP-AES法测定煤气化废水催化剂中锰铜铁的含量
  

本文利用电感耦合等离子体发射光谱ICP-AES)法进行了煤气化废水催化剂中锰、铜、铁含量测定方法研究,试样经王水和氢氟酸溶解后,对溶解方法及待测元素间的相互作用做了试验,选择合适的分析谱线,建立了同时测定锰、铜、铁元素的分析方法,方法回收率在95%103%之间,相对标准偏差均小于5%。实验结果表明:本方法具有准确、简单、快速的优点。

this paper studies application of ICP-AES for determining the elements of mangancese, copper and iron in Coal gasification wastewater catalysts. The sample was disolved by Aqua regia and hydrafluoric acid and the relative tests are done for sample disoving methods and interferencs between determined elements .At the same time the optumim analyzing bands were selected. The standard recovery rates are from 95% to 103%, the relative standard derivation for various elements are smaller than 5%. So far, the method was established for simutaneous determining multiple elements. It is shown that the experiment has the advantage of acuracy,sample and rapid.
