微胶囊法富集Pd(Ⅱ)的研究
Enrichment of Pd(Ⅱ) by means of Microcapsule Containing TOA
【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。
【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.
