摘要：

The solubility in the system formed by the oxyethylated anionic surfactant potassium bis(alkylpolyoxyethylene)phosphate (oxyphos B), the cationic surfactant alkyldimethylbenz-ylammonium chloride (cathamine AB), and water was studied. The optimal parameters of the extraction process in the systems based on the mixture of surfactants, whose aqueous solutions have the lowest phase-separation temperatures, without a salting-out agent and in the presence of (NH4)(2)SO4 were established. A possibility of the extraction of metal cations in the oxyphos B-cathamine AB-water system at 50 degrees C, and the (NH4)(2)SO4-oxy-phos B-cathamine AB-water system at 25 degrees C was demonstrated. The advantages of application of a mixture of ionic surfactants as compared to the systems based on individual surfactants were revealed.
