Abstract
담체로 아민을 함유한 격막형 액막을 사용하여 침출모액의 산도, 담체의 농도, 우라늄이온의 농도의 우라늄 전달속도에 미치는 영향을 고찰하였다. 이온의 전달은 주로 액막내의 확산속도에 영향을 받는다고 가정하여 이론식을 전개하였다. 우라늄이온의 아민에 대한 추출계수를 이용하여 구한 이론식은 실험치와 잘 일치하였으며, 우라늄이온의 최대 전달속도는 pH1.3, 담체농도 30%에서 나타났다.
The effects of acidity, solute and carrier concentration on the mass transfer rate were investigated in a supported liquid membrane system where uranium and amine were used as the solute and carrier, respectively. The theoretical uranium permeation rate was developed assuming that the rate determining step was to depend dominently upon the diffusivity of uranium complexes within the membrane. The maximum value of the uranium flux was ob-tained at pH1.3 and 30volume percent of amine.
