摘要
本文介绍应用ICP-AES法测定催化剂中Pt和Pd的分析方法,干扰元素的去除采用巯基棉柱分离法,这是基于在HCI浓度达3mol/L时,巯基对Pd和Pt离子仍具有较强的吸附力。实验选定了最佳吸附酸度和洗脱条件,Pd的回收率为91.3~106%,Pt的为92~103%。
A method for the determination of Pd and Pt in catalyst by ICP--AES is introduced.Sulfhydryl cotton column is used to separate interferential elements based on the strong combination between Pd2+ (or Pt2+ )and sulfhydryl in 3 mol/L HCI concentration. The best separation condition is selected. Recoveries of Pd and Pt are 91. 3 ̄106 % and 92 ̄103 % respectively.
