摘要：
The possibility of determining of chromium (III) ions was investigated in this paper. It is shown that the electrode on a basis of heazlewoodite shows high selectivity to chromium (III) ions. Also the stability constants of complexes of chromium (III) ions with a carbamide were determined by potentiometric titration. The amount of chromium (VI) ions in model solutions and wastewater JSC "Mittal Steel Temirtau" (Kazakhstan) was determined by amperometric and potentiometric methods. The data were processed by methods of mathematical statistics.
