  Abstract

25 oC의 순수 물에서 음이온성 계면활성제인 DBS(sodium dodecyl benzenesulfonate)와 SDS(sodium dodecylsulfate) 그리고 비이온성 계면활성제인 Brij 30(polyoxyethylene(4) lauryl ether) 사이의 혼합미셀화에 대한 임계미셀농도(CMC)와 반 대이온의 결합상수값(B)을 전도도법과 표면장력계법으로 측정하였다. 이와 같이 측정한 CMC값에 비이상적 혼합미셀화 모 델을 적용함으로써 여러 가지 열역학적 함수값(Xi, γi, Ci, ai M, β 및 ΔHmix)들을 계산하여 상호 비교분석하였다. 그 결과, SDS는 DBS보다 Brij 30과 더욱 강한 상호작용을 이루었으며, SDS/Brij 30 혼합계면활성제가 이상적 혼합미셀화로부터 가 장 큰 음의 벗어남을 보였다. 그리고 SDS/DBS 혼합계면활성제는 거의 이상적 혼합미셀화를 이루는 것으로 나타났다. The critical micelle concentration (CMC) and the counter ion binding constant (B) for the mixed micellizations of DBS (sodium dodecylbenzenesulfonate), SDS (sodium dodecylsulfate), and Brij 30 (polyoxyethylene(4) lauryl ether) at 25 oC in pure water were determined by the use of electric conductivity and surface tension measuring methods. Various thermodynamic parameters (Xi, γi, Ci, ai M, β, and ΔHmix) were calculated and compared with each other mixed surfactant system by means of the equations derived from the nonideal mixed micellar model. The results show that the SDS molecule interacts more strongly with Brij 30 molecule than DBS molecule and that the SDS/Brij 30 mixed surfactant system has the greatest negative deviation from the ideal mixed micellar model and the SDS/DBS mixed system has followed almost the ideal mixed micellar model.
