The possibilityof determining of chromium III, VI ions was investigated in this paper. It isshown that the electrode on а basis of heаzlewoodite has high selectivity tochromium III ions. Also the stability constants of complexes, forming insystem -Cr3+-Mohr’s salt-CaOH2-PVA ÷ PAA- were determined by potentiometric titration with ion-selectiveelectrode.

KEYWORDS
