摘要: ABSTRACT The critical micelle concentration of mixtures anionic and nonionic surfactants was measured. were alkylbenzene sulfonates the polyoxyethylene nonylphenols a polyoxy-ethylene alcohol. effect added electrolyte, number ethylene oxide units in polyethoxylate, alkyl chain length studied. All systems showed substantial negative deviations (lower CMC) from ideal solution theory. results can be represented by regular Charge separation appears to source nonideality. This considers reduction electrostatic repulsion between ionic surfactant head groups mixed micelle, due insertion hydrophilic these charged groups, cause enhanced formation. physical basis theory shown consistent with charge effect.
