Abstract

Solvent extraction experiments have been performed to separate Gd and Nd from chloride solution with PC88A and saponified PC88A. In the experimental ranges conducted in this study, the extraction percentage of Gd was higher than that of Nd. Use of 40% saponified PC88A increased the distribution coefficients of Gd and Nd. A chemical model was developed to predict the distribution coefficients of the two metals from the initial extraction conditions. The measured distribution coefficients of Gd and Nd with PC88A and saponified PC88A agreed well with those calculated in this study.

Gd와 Nd이 혼합된 염산용액에서 PC88A와 비누화 PC88A에 의한 용매추출실험을 하였다. 본 연구에서 수행한 실험조건에서 H88A에 의해 Gd이 Nd보다 추출이 잘 되었으며, 40% 비누화된 H88A를 사용하여 Gd와 Nd의 분배계수가 증가하였다. PC88A와 비누화 PC88A에 의한 추출시 초기추출조건으로부터 Gd와 Nd의 분배계수를 예측할 수 있는 모델을 개발하였다. 본 연구에서 개발된 모델을 초기추출조건에 적용하여 예측한 Gd와 Nd의 분배계수는 실험으로 측정한 값과 서로 잘 일치하였다
