Abstract:

Solid-contact chromium-selective film electrodes were prepared on the basis of titanium diselenide and titanium ditelluride intercalated with chromium. It was found that the titanium diselenide-based electrode with the lowest concentration of the intercalant (Cr0.1TiSe2) exhibits the best properties and provides the determination of 5 X 10(-5)-1 X 10(0) M chromium(HI) in the pH range 2.75-4.7. The slope of the electrode function for all chromium-selective electrodes depends on the pH of the solution and is close to the theoretical slope for the singly charged Cr(OH)(2)(+) ion. It was demonstrated that chromium-selective electrodes can be used as indicator electrodes in determining chromium(III) by direct titration with the potentiometric detection of the titration end-point using EDTA and KMnO4 as titrants.
