Abstract

The extraction and stripping of HCl from aqueous solutions by commercial extractants like LIX 63 and its mixture with TEHA/ Cyanex 923/ Aliquat 336 and ionic liquids like ALi-SCN, ALi-PC in kerosene was investigated. Among these extractants, ALi-PC showed the best extraction effectivity (above 80%), but it was difficult to strip HCl from the loaded phase. Although the extraction percentage of HCl by LIX 63 was not high, the stripping performance was above 81%. The addition of octanol to the organic phase led to negative effect on the extraction performance of HCl. The addition of C₂H₅OH into aqueous solutions significantly increased the extraction and stripping percentage of HCl by LIX 63, ALi-PC and ALi-SCN.

염산의 용매추출 및 탈거 거동을 조사하기 위해 상용화추출제인 LIX 63 단독 및 TEHA/ Cyanex 923/ Aliquat 336의 혼합추출제와 ALi-SCN과 ALi-PC 이온성액체를 사용하였다. 상기 추출제중에서 ALi-PC가 가장 높은 추출률(80%)을 보였으나 탈거가 어려웠다. 반면 LIX 63의 경우 추출률은 낮았으나, 탈거율은 81%로 가장 높았다. 옥탄올을 유기상에 첨가하면 염산 추출이 오히려 감소했다. 에탄올을 염산용액에 첨가하면 LIX 63, ALi-PC, ALi-SCN에 의한 염산의 추출과 탈거 거동이 크게 개선되었다.
