Abstract
The possibility of determining of chromium (III, VI) ions was investigated in this paper. It is shown that the electrode on а basis of heаzlewoodite has high selectivity to chromium (III) ions. Also the stability constants of complexes, forming in system “Cr 3+ -Mohr’s salt-Ca(OH) 2 -PVA ÷ PAA” were determined by potentiometric titration with ion-selective electrode.
