废催化剂中铂族金属分析的取样研究

Study on Sampling of the Spent Catalyst in Platinum Group Metal Analysis

对各种含钯废催化剂取样方法的研究表明，对于大量的桶装废料，采用管枪取样法对获得代表性的样品是最适用的。同时给出了几种废钯催化剂中钯含量的正确分析结果。

Sampling on the spent catalyst containing palladium is investigated.For a lot of drum scrap materials,sampling by tube spear to obtain representative sample is the optimal method.The accurate content of palladium in several spent catalysts are provided.
