Abstract

액막을 이용한 페놀제거시의 실험조건을 사용하여 에멀젼형 액막에 대한 수식모델을 비교, 분석하였다. 의정상상태를 가정하여 하나의 Water-in-Oil（W/O） 에멀전액적에 대한 총괄추출속도식을 유도하였다. 율속단계개념을 이용하여 제안된 각 모델이 적어도 각 연구자의 W/O 에멀젼 제조조건하에서는 각기 타당함을 밝혔다. 추출속도 증대를 위한 W/O에멀젼 제조방안을 제시하였다.

Mathematical models for emulsion-type liquid membrane were compared and analyzed using the experimental conditions of phenol removal from waste water. Overall extraction rate equation for a single water-in-oil （w/o） emulsion globule was derived under the pseudo-steady state approximation.
By means of the concept of rate controlling step, each proposed model was proved good under each investigator's w/o emulsion preparation conditions, at least.
Some helpful w/o emulsion preparation schemes were proposed for the increase of extraction rate.
