초록
In, Ga, Fe, Al이 함유되어 있는 혼합용액으로부터 In을 분리하기 위해 D2EHPA를 이용한 용매추출 연구를 수행하였으며, In의추출에 대한 수상의 HCl 및 추출제 농도 효과를 확인하였다. In과 Ga의 추출률은 HCl 농도의 감소에 따라 증가하였지만, Fe와 Al 의 추출률에는 큰 영향을 미치지 않았다. In과 Ga의 분리인자(DIn/DGa)는 1.0 M D2EHPA, 0.5 M HCl조건에서 115로 나타났다. 즉, D2EHPA는 혼합용액으로부터 In을 분리하는 추출제로 적합하며, 추출률 및 분리인자는 HCl 및 추출제의 농도 조절을 이용하여 조절할 수 있다.
Abstract
The separation of In from the synthesis solution with Ga, Fe, and Al has been studied by the solvent extraction using D2EHPA as an extractant. The effects as a function of the concentration of extractant and HCl on the extraction of In were investigated. The extraction of In and Ga increased with decreasing HCl concentration, but that of Fe and Al was independent. Separation factor between In and Ga of 115 was obtained at 1.0 M D2EHPA in the presence of 0.5 M HCl of feed solution. Consequently, this study shows that D2EHPA is suitable extractant for In extraction from the synthesis solution. Extraction efficiency and separation factor could be increased by controlling HCl and extractant concentration.
