벤젠-노말헵탄 혼합물의 액막분리에 있어서 초음파균질화의 효능
Efficacy of Ultrasonic Homogenization in the Separation of Benzene-n-Heptane Mixture by Liquid Membrane
액체막에 의하여 벤젠-노말헵탄 혼합물을 분리함에 있어서 초음파균질화의 효능에 대하여 연구하였다. 사용한 계면활성제로는 두 종류의 음이온 계면활성제로 트리에탄올아민 로릴 썰페이트와 소디움 폴리옥시 에틸렌(2) 로릴 에테르 썰페이트이다. 초음파균질화에 의하여 얻은 분리계수의 최고치를 같은 조건에서 기계적 교반에 의하여 얻은 분리계수의 최고치와 비교하여 보면 트리에탄올아민 로릴 썰페이트의 경우에는 약 세 배이고 소디움 폴리옥시에틸렌(2)로릴 에테르 썰페이트의 경우에는 약 한 배 반이었다 소디움 폴리옥시에틸렌(2)로릴 썰페이트를 사용하였을 경우 가장 좋은 분리계수를 나타내었을 때 가장 적은 액막 파괴를 관찰하였다.
In the separation of benzene-n-heptane mixture by liquid membrane, the efficacy of ultrasonic homogenization in emulsification was studied with two anionic surfactants. The two anionic surfactants used were triethanolamine lauryl sulfate and sodium polyoxyethylene(2) lauryl ether sulfate. The highest value of the separation factor obtained by ultrasonic homogenization was approximately three times as large as that for triethanolamine lauryl sulfate and one and a half times as large as that for sodium polyoxyethylene(2) lauryl sulfate when the mechanical stirring was used on the same operational conditions. The lowest membrane breakup was observed when the highest value of the separation factor was achieved with sodium polyoxyethylene(2) lauryl sulfate.
