초록
황산용액중에서 바나듐 및 티타늄의 추출거동을 고찰하기 위하여 추출제로 Cyanex272, PC88A 그리고 Alamine336를 추출제로 사용하였다. 용액의 pH 및 추출제의 농도 그리고 추출등온곡선에 대한 연구와 바나듐 및 티타늄의 혼합용액에서 두성분의 분리성에 대한 연구를 실시하여 바나듐 회수를 하기 위해 효과적인 추출제를 선정하고자 하였다. 실험 결과로부터 Alamin336이 바나듐의 추출효과가 가장 좋았고, 티타늄과의 분리성도 가장 우수하였다.
Abstract
A comparative study of the extraction behavior of vanadium and titanium in sulphate solutions using Cyanex272, PC88A and Alamine336 has been carried out. Effect of pH in sulphate solutions, concentration of extractant and extraction isotherms has been studied. Solvent eatraction separation studies of vanadium and titanium from the mixed solutions were also carried out in order to obtain a criterion for choosing the more effective extraction regent. From the experimental results, it was conformed that Alamine336 was good extractant to extaction of vanadium and separation from titanium from the mixed solutions.
