Shibata等曾用5-Cl-PADAB(4-[5-氯-2-吡啶偶氮]-1,3-二氨基苯)测定纯溶液中的钯;杨滨湖等结合火法试金用于矿石中钯的测定;童沈阳等对5-Cl-PADAB与钯在水溶液中的反应进行了较全面的分光光度研究。但是关于Pd-5-Cl-PADAB络合物的萃取性能研究报导很少,仅见卜卫红等用正戊醇
Shibata et al. Used 5-Cl-PADAB (4- [5-chloro-2-pyridylazo] -1,3-diaminobenzene) to determine palladium in pure solution; Determination of palladium; Tong Shenyang and other 5-Cl-PADAB and palladium in aqueous reaction conducted a more comprehensive spectrophotometric study. However, there are few reports about the extraction performance of Pd-5-Cl-PADAB complexes.
