【摘要】 将芯材为ＴＯＡ（三正辛胺）的微胶囊填充于玻璃柱中，作为离子的富集装置。使含Ｐｄ（Ⅱ）４ｍｇ／Ｌ的原料液流过填充柱，可以定量地萃取和洗脱。在适当条件下，萃取率可以达到９９％以上，再用氨水进行洗脱，最大洗脱率为９８％。回收液中Ｐｄ（Ⅱ）相对原料液的富集倍数约１４倍。更多还原

【Abstract】 The microcapsule containing TOA (Trioctyl Amine) was stuffed into a column, which can act as an extractor for enrichment of Pd(Ⅱ). It can extract and strip Pd (Ⅱ) to 4mg/L Pd (Ⅱ) original solution quantitatively. Under proper conditions, the extraction ratio is over 99%. And its stripping ratio is about 98% with NH4OH stripping agent ,the enrichment times is about 14 to the original solution.更多还原
