Abstract: Extraction process based on reversible chemical complexation has high capacity and high selectivity for dilute polar orgnic solution. In this paper, extraction of p-toluene-sulphonic acid, sulphosalicylic acid with a tertiary amine (7301) in octanol, CHCl3, CCl4 or kerosene has been studied. The effects of diluents, pH and concentration of a tertiary amine(7301) on the distribution ratio D have been investigated. The composition of complex has been determined. -
