采用固定时间法，用ＨＰＬＣ作检测技术，研究了钯（Ⅱ）－亮绿－次亚磷酸盐催化体系，建立了一个贵金属钯的ＨＰＬＣ分析新方法，其测定范围和检出限分别为０．８～５０ｍｇ／Ｌ和０，３ｍｇ／ＬＰｄ，已用于催化剂中痕量钯的分析．
A fixed time method was used to detect the palladium (Ⅱ) - bright green - hypophosphite catalytic system by HPLC. A new HPLC method for the determination of palladium was established. The determination range and the detection limit were 0. 8 ~ 50mg / L and 0,3 mg / LPd, has been used for the analysis of trace palladium in the catalyst.
