摘要：

According to the study of phase equilibria in a neonol AF 9-10-neonol AF 9-12-water system made by the visual polythermal method, the immiscibility area in the system exists at temperatures above 68(degrees)C and its formation is associated with a limited solubility of the surfactant in water at the temperatures studied. The conditions for the quantitative extraction of thallium(iii) in the form of bromide and thiocanate complexes and iron(iii) in the form of thiocyanate complexes in the neonol AF 9-10-water system at 85(degrees)C were established. The use of a mixture of neonols in the absence of a salting agent gives no special advantages over the use of the neonol AF 9-10-water system.
