Investigation of the extraction equilibrium of ternary ion-association complexes of thallium(III) with monotetrazolium salts triphenyltetrazolium chloride and thizolyl blue

The extraction equilibrium of ternary ion-association complexes obtained during the reaction of tetrachloride complex of thallium(III) and monotetrazolium salts triphenyltetrazolium chloride (TTC) or thiazolyl blue (MTT) has been studied. The optimum conditions that are required to carry out the investigations have been found. As a result of using a developed chemical model, the constants of extraction, distribution and association, the distribution coefficients and the recovery factor of investigated ionassociates have been determined radiochemically.
