摘要
研究了含羧基的聚乙烯醇胺肟（ＰＶＡＡＯ－ＡＡｃ）螯合纤维对钯的吸附。讨论了ｐＨ、温度、浓度、吸附时间对吸附率及回收率的影响。确定了最佳吸附条件，吸附钯的纤维用５％硫脲＋０．１０ｍｏｌ／Ｌ硝酸溶液可以解吸。
The effects of pH, vibration time, solution temperature and concentration of solution on adsorption rate and recovery rate have been discussed. The most suitable adsorption condition was determined. The Palladium can be desorbed with mixsolution of 5% thiourea and 0.10 mol/L HNO3
