초록

저준위 방사성 액체폐기물의 새로운 감용방법으로써 cellulose acetate막을 사용한 투과증발법의 연구가 수행되었다. 실험결과에 의하면 일반적으로 유기물의 분리에 사용되는 투과증발법은 액체폐기물의 감용을 위한 제염효과가 우수하였고, 수분의 증발속도도 저준위 방사성 액체폐기물의 감용을 위해 널리 사용되는 자연증발에 비해 현저히 빨랐다. 또한 주입용액의 조건에 따른 실험결과를 토대로 투과증발특성을 평가하였으며, 투과증발량을 증가시키기 위해 cellulose acetate막의 최적제막조건을 설정하였다.

As a promising method for the volume reduction of the low-level liquid waste, the pervaporation process was studied using a cellulose acetate membrane. Experimental results showed that the pervaporation method, usually applied to separation of organic materials, has a good decontamination effect for the volume reduction of liquid waste and the evaporation rate of water in this process was markedly faster than that of natural evaporation method, a wide-used process for the volume reduction of liquid waste. Depending on the feed solution conditions, the pervaporation characteristics were evaluated by the experimental results and the optimum conditions for preparation of the cellulose acetate membrane were established to increase the pervaporation flux through the membrane.
