摘　　要：The extraction of Zr(Ⅳ) from nitric acid solution with amido polands PAⅡ、PAⅤ [1] was studied.The effects of the concentration of Zr(Ⅳ) and HNO 3,salting out agent(NaNO 3) and extractant on the distribution ratios were observed,the results show that the extractant PAⅡ is satisfactory for the extraction of Zr(Ⅳ) but there appears a serious emergence of third phase when the concentration of salting out agent and the rate of the concentration of the extractant/Zr(Ⅳ) is over some range and PAⅤ is of disadvantage on the extraction of Zr(Ⅳ).The extraction of Zr(Ⅳ) from nitric acid solution with amido polands PAⅡ、PAⅤ [1] was studied.The effects of the concentration of Zr(Ⅳ) and HNO 3,salting out agent(NaNO 3) and extractant on the distribution ratios were observed,the results show that the extractant PAⅡ is satisfactory for the extraction of Zr(Ⅳ) but there appears a serious emergence of third phase when the concentration of salting out agent and the rate of the concentration of the extractant/Zr(Ⅳ) is over some range and PAⅤ is of disadvantage on the extraction of Zr(Ⅳ).
