Abstract

본 연구는 염화네오디뮴 수용액으로부터 Fe 성분 제거를 위하여 Alamine 336을 이용한 Fe의 용매추출을 수행함에 있어서, Alamine 336의 농도, 염산 및 염소이온 농도에 따른 Fe 추출 특성 및 유기상으로 추출된 Fe의 탈거공정에 있어 상비와 탈거 용액의 염산 농도의 영향들을 고찰하였다. Alamine 336을 사용하여 Nd, Fe 혼합 용액으로부터 Fe 만을 선택적으로 추출할 수 있다는 것을 확인하였으며, 수상의 염산 및 염소이온 농도 증가에 의해 Fe의 추출율이 증가하였다. Fe가 추출된 Alamine 336을 증류수로 탈거할 경우 A/O비 4인 조건에서 99%의 Fe를 탈거할 수 있었으며, 탈거 용액의 염산 농도가 증가할수록 Fe 탈거율이 감소하였다.

The removal of iron from neodymium chloride solution was carried out by solvent extraction using Alamine 336 in kerosine. The effect of Alamine 336, hydrochloric acid and chloride ion concentrations on the extraction of Fe were studied. The results showed that Alamine 336 as an extractant for removal of iron was effective and the extraction percentage of iron was increased with increasing hydrochloric acid and chloride ion concentration in aqueous solution. The extraction of 99% of iron is attained at a ratio of A/O = 4 by distilled water. The stripping yield of iron from loaded Alamine 336 decreased with decreasing hydrochloric acid concentration in stripping solution.
