摘　　要：Pd 2+ and other metal ions were chelated with EDTA, and the Pd\|EDTA chelate was decomposed with NaNO\-2 as releasing agent . The lilerated EDTA was then back\|titrated with Zn 2+ standard solution. The method has been used in the determination of palladium in Pd\|Cu, Pd\|Sn\|Cu and Pd\|Ti\|Si alloys.Pd 2+ and other metal ions were chelated with EDTA, and the Pd\|EDTA chelate was decomposed with NaNO\-2 as releasing agent .
