Abstract

Solvent extraction experiments of Mn(II) by Cyanex 301 has been done from chloride solutions. The effect of variables, such as the initial pH and the concentration of Mn and extractant, on the extraction of Mn was investigated. The solvent extraction reaction was identified by applying a slope analysis method to the extraction data. In order to estimate the equilibrium constant for this solvent extraction reaction, the activity coefficients of aqueous species as well as the complex formation reactions between Mn and chloride ion were considered. Bromley equation was employed to calculate the activity coefficients. It was possible to predict the distribution coefficients of Mn from initial extraction data by employing the equilibrium constant. There was a good agreement between the experimentally measured distribution coefficients of Mn(II) and those predicted in this study.

염산용액에서 Cyanex 301에 의한 망간의 용매추출실험을 수행했다. 수상의 초기 pH와 망간 및 추출제의 농도가 망간의 추출에 미치는 영향을 조사했다. 추출실험자료에 기울기법을 적용하여 추출반응을 규명하였다. 추출반응의 평형상수를 추산하기 위해 수상에서 망간과 염소이온간의 착물형성반응과 활동도계수를 고려하였다. 이와 같이 평형상수를 이용하여 초기 추출조건으로부터 망간의 분배계수를 예측하는 것이 가능하였다. 실험에서 얻은 망간의 분배계수값과 계산값은 서로 잘 일치하였다.
