Abstract

Solvent extraction experiments for the separation and recovery of Re from hydrochloric acid leaching solution of spent super alloy by Alamine 304-1 were carried out. The effects of some variables, such as the nature and concentration of the extractants, HCl concentration, and the presence of impurities were investigated. The synthetic solutions of Re were prepared by dissolving ammonium perrhenate (APR), Alamine304-1, Cyanex272 and $D_2EHPA$ were used solvent extractants distilled in kerosene. The extraction percentage of Re by Alamine304-1 was higher than the other extractants as Cyanex272 and $D_2EHPA$ and the percentage is about 99%. Only 99% of Re was extracted in the presence of Al, Co and V in HCl solution.

폐 초내열합금으로부터 침출된 염산용액에서 레늄을 회수하기 위하여 용매추출법을 이용한 레늄의 분리연구를 수행하였다. 용매추출공정을 통해 수상은 레늄이 용해된 합성용액을 사용하고 추출제의 종류 및 농도, 수상의 pH, HCl의 농도, 불순물의 영향을 조사하는 연구를 진행하였다. 레늄의 원료로 Ammonium perrhenate ((APR), Aldrich, $NH_4ReO_4$)을 사용하였고, 수상에 존재하는 레늄을 유기상으로 추출하기 위해 추출제는 음이온추출제인 Alamine304-1, 양이온추출제인 Cyanex272과 $D_2EHPA$를 사용하였다. 음이온추출제인 Alamine304-1 사용시 레늄의 추출율이 99% 이상 나타났으며 수상의 pH 는 0-2 사이에서 99% 추출되었다. Alamine304-1의 농도를 0.1, 0.5, 1 및 2%으로 조절하여 추출실험한 결과, 농도가 증가함에 따라 추출율이 증가한다. 레늄용액에 알루미늄, 코발트, 바나듐을 첨가하여 용매추출법에 의해 분리 실험한 결과 레늄은 99.8 %으로 추출되었으나 기타 금속들은 거의 추출되지 않았다.
