Abstract

Stripping experiments of iron from the loaded Alamine336 by sulfurous, chloric and sulfuric acid solutions have been performed by varying the concentration of acid and stripping conditions. The stripping percentage of iron decreased with the increase of HCl and $H_{2}SO_4$ concentration, while that increased with the increase of $H_{2}SO_3$ concentration up to 3 M. Stripping temperature had adverse effect on the stripping percentage of iron in the stripping by $H_{2}SO_3$ solution, while the stripping percentage of iron by HCl solution increased with the increase of temperature. Stripping isotherm of iron by 0.1 M HCl and 0.1 M $H_{2}SO_4$ solution indicated that three and four stripping stages could result in a solution containing 0.05 M iron at an O/A ratio of 1/10 from the loaded Alamine336 phase where iron concentration was 0.5 M.

Alamine336에 추출된 염화 제 2철의 탈거실험을 위해 아황산과 염산 및 황산용액의 농도와 탈거조건을 변화시키며 탈거실험을 수행했다. 염산과 황산용액의 농도가 증가함에 따라 철의 탈거율은 감소했으나, 아황산용액의 경우에는 3M의 농도범위에서 산의 농도에 따라 탈거율이 증가하였다. 탈거온도가 증가하면 아황산용액에 의한 철의 탈거율은 감소하나, 염산용액의 경우에는 탈거율이 증가하였다. 0.5M의 철이 함유된 유기상으로부터 O/A=1/10의 조건에서 0.1 M의 염산의 경우에는 3단에 의해, 0.1M의 황산용액으로는 4단에 의해 0.05M농도의 철이 탈거된 용액을 얻을 수 있는 것을 등온탈거곡선으로부터 알 수 있었다.
