Abstract：Nonionic surfactants mixed with cosurfactants were used to absorption of toluene, and the absorption capacity was predicted according to the apparent Henry’s law constants obtained by solubilization experiments. The results indicated that surfactant solutions could remarkable enhance touene solubility when the concentration of surfactants was above critical micelle concentration (CMC). The apparent toluene solubilities were proportional to Tween-20 concentration. The efficiency of cosurfactants to enhance toluene solubility followed the order: n-butylamine > butanol > butyric acid. The prediction of absorption capacity with apparent Henry’s law constant was practicable with average relative deviations of 7.34% and 8.85%.
