通过铅试金富集树脂中的钯并用银作钯灰吹保护,得到的银钯合粒用王水溶解,在5%的盐酸介质中,采用原子吸收光谱法测定钯,该法测钯的相对标准偏差RSD为0.53%,加标回收率在99.04%~100.10%之间。
通過鉛試金富集樹脂中的鈀併用銀作鈀灰吹保護,得到的銀鈀閤粒用王水溶解,在5%的鹽痠介質中,採用原子吸收光譜法測定鈀,該法測鈀的相對標準偏差RSD為0.53%,加標迴收率在99.04%~100.10%之間。

Palladium in resin was enriched by lead assaying, using silver as a protective agent to produce silver-palladium alloy, and then the alloy was dissolved in aqua regia. Air acetylene flame atomic absorption spectrometric method was used to determinate palladium in 5%hydrochloric acid solution. The relative standard deviation (RSD) in determination of palladium is 0.53%and the recovery rate is between 99.04%~100.10%.
