摘要
本文研究了用聚乙烯苄硫脲螯合树脂富集溶液中的微量元素钯和用原子吸收法测定钯的条件。本法选择性好,回收率高(97％～102％),操作简便。可对天然水及对用钯作催化剂的工业废水中的钯含量进行测定。
The conditions of concentrating Pd with thiourea resin TUR and determining with AAS are given.The recovery of Pd is 97%～102%. This is a simple, accurate and highly selective method which can be used to determine trace Pd in natural water and industrial waste water.
