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.
