Catalytical Kinetics Spectrophotometry Determination of Pd in Electroplating Solution
Abstract
利用痕量Pd￣（2＋）在HCl介质中的催化作用建立了Pd的催化动力学分光光度测定法，测定线性范围：40~200gPd/Ml。应用于电镀中Pd含量的测定，相对标准偏差在2.5%以内，回收率为97.0~101.0%。电镀液中的7种添加剂对Pd的测定无干扰。 A catalytical kinetics spectrophotometry has been established For determinating of Pd base on the catalysis of trace amounts of Pd2+in HCl medium.Linear range of the method covers 40～200ng Pd/ml.The method can be used to determinate the contents of Pd in electroplating solutions with a standard deviation less than 2.5% and 97～101.1% of recoveries 7 aditional agents in the electroplating solutions didn't disturb the determination.
