摘要
论述了将ＰＭＢＰ和ＴＴＡ协萃剂负载于聚醚型聚氨酯泡沫塑料上，萃取微量稀土元素钪、钇、钕、铒的最佳实验条件（萃取剂浓度、温度、酸度）。研究了它们的萃取性能（萃取百分率、分配比、萃取容量）。说明这是可行的萃取方法。
The best experiment conditions (such as the concentration of extraction agent, temperature, acidity) were studied, when microamounts of rare earth Sc 3+ , Y 3+ , Nd 3+ and Er 3+ were extracted by loaded foamed polyurethane (polyether type) with synergistic reagent PMBP and TTA. The performance of extraction (percentage extraction, ratio of separation, extraction capacity) was investigated. It was proved that this is a practical method of extraction.
