The equimolar mixed system of decyltriethylammonium bromide and sodium decylsulfonate, which was homogeneous solution even with the total surfactant concentration increasing up to 0.2 mol•L－1, formed aqueous two-phase system(ATPS) when salts, such as NaF, Na2SO4 or Na3PO4, were added. The phase behavior and partitioning of BSA in this saltinduced ATPS were studied. Compared with the usual ATPS of catanionic surfactant mixtures, this salt-induced ATPS exhibited some special advantages, and overcame some shortcomings of the usual ATPS. It was shown that the phase behavior of this salt-induced ATPS could be adjusted by adding salts and the partition coefficient of BSA could be altered and optimized by salt species.
