Investigation of rhenium (5) complexing with 3-methyl-4-phenyl-1,2,4-triazolethiol-5 in 6 M HCl medium

3-methyl-4-phenyl-1,2,4-triazolthiol-5 (3-Met-4-PTT) base and R-S-S-R/RS base where RS=3-Met-4PTT (ligand electrode) new reduction-oxidation system was elaborated. Values of the real potential of this system in 6 M HCl medium within 273-338 K temperature range are determined. Complex formation of rhenium (5) with 3-Met-4-PTT in 6 M HCl medium under different temperatures is studied potentiometrically by means of the developed ligand electrode. The values of thermodynamic functions of complex formation of rhenium (5) with 3-Met-4-PTT are estimated. 9 refs., 5 figs., 6 tabs
