摘要
研究了在ｌｍｏｌ／ｌＨＮＯ＿３介质中用蜜胺树脂柱色谱法从模拟高放废液中回收钯。结果表明，蜜胺树脂柱色谱法能有效地分离钯，吸附容量可达５０—７０ｍｇ／ｇ吸附的钯可用３％硫脲溶液解吸；蜜胺树脂有抗辐照性能。本方法在高放废液及贵金属提取工艺中分离回收钯等方面有应用前景。
The recovery of pa11adium from high-leve1 1iqud wastes by chromatographic absorbing onthe melamine resin column is studied.The results show that palladium can effectively be absorbedwith an absorption capacity of 50 70mg/g. The palladium absorped on the resin phase can beeluated with 3%thiourea solution quantitatively. Irradiation hardly has any effect on the propertyof melamine resin for absorption of palladium.
