Study of Interaction and Distribution of Mixed System of Anionic and Nonionic Surfactants Between Toluene and Water

ABSTRACT

We determined the concentrations of petroleum sultanate and labelled AP type surfactants under the distributions of petroleum sultanate and labelled AP type surfactants alone and their mixed system to using HPLC and radiosoptic tracer. The interaction between the above two kinds of surfactants in the partitioning process was described quantitively under CMC using the formula related to partition coefficient and Thermodynamic functions. It was found that the interaction between petroleum sultanate and labelled Ap211 was the strongest interaction among the petroleum sultanates and hi helled A P type surfactants or various HLB.
