The applicability of the positron annihilation technique is discussed as a simple method for the accurate determination of the critical micelle concentration (cmc). The results of a preliminary study of positron interactions in solutions with various amounts of surfactants present are reported. The six different micellar systems studied were dodecylammonium propionate in benzene, cyclohexane, and n-hexane; sodium di(2-ethylhexyl)sulfosuccinate in benzene; sodium decylsulfate and decyltrimethylammonium bromide in water. The tabulated results indicated that this technique was applicable to the determination of cmc's in both aqueous and nonaqueous solutions. (BLM)
