사차 암모늄 염을 함유하는 농축된 콜로이드 액상 에이프런의 연속상에서의 안정성

Abstract

In this study, the stability of concentrated colloidal liquid aphrons (CLAs) containing Aliquat 336 was measured. CLAs in the continuous phase are stabilized by water-soluble surfactant and oil-soluble surfactant. To compare the stability of CLAs, half-life was introduced. According to the change of state of solution, the rate of break-up of concentrated CLAs changed rigorously at critical coagulation concentration. Critical coagulation concentration was measured with changing pH. The effects of ionic strength and concentration of Sodium Dodecyl Benzene Sulfonate (SDBS) on the stability of concentrated CLAs in the continuous phase were also investigated.
