摘要
研究了用MCI-GEL树脂分离富集钯的行为及钯与一些金属离子分离的条件。结果表明,在0.1mol/L的盐酸介质中,当2×10-2 mol/L 4,4′-二氨基二苯砜存在时,钯与4,4′-二氨基二苯砜形成的配合物能被MCI-GEL树脂吸附(钯的萃取率可达99%),且吸附在树脂上的钯能被酸性硫脲和无水乙醇的混合洗脱剂洗脱,实现了Pd?与Fe?、Ni?、Cu?、Zn?离子的定量分离。方法用于合成试样中钯的分离,效果良好。
The separation and enrichment behavior tion conditions for palladium from some metal ions of palladium with MCI-GEL resin and the separa- were investigated. The results showed that in the presence of 2 × 10^-2 mol/L 4,4＇-diamino dip-henylether, the complex formed by palladium and 4,4＇- diamino dip-henylether could be absorbed by MCI GEL resin （palladium extraction rate reaching 99%） in 0.1 mol/L hydrochloric acid medium, and the palladium adsorbed on the resin could be eluted by the mixed eluant of acidic thiourea and absolute of Pd （Ⅱ） from Fe （[Ⅲ）, Ni（Ⅱ）, Cu （Ⅱ） and Zn（Ⅱ） ions ethanol. Consequently, the quantitative separation could be realized. The method was applied to the separation of palladium in the synthetic sample, and the result was satisfactory.
