DETERMINATION OF HEAVY AND TOXIC METAL IONS FROM INDUSTRIAL WASTEWATER COMPOSITION BY INVERSION VOLTAMPEROMETRIC METHOD

Abstract

One of the modern electrochemical methods of analysis, the inversion voltammetric analysis method provides the possibility to determine the concentration of substances in a wide range (from 1 to 1·10-9 mol/l), is easily automated, and is widely used in food quality control. is used. Inversion-voltammetric methods of analysis are used in industry for analytical control of the concentration of saline solutions, salt content of ground and underground waters, control of water quality and treatment, assessment of wastewater pollution. In our research work, the presence of copper(II) and zinc(II) ions in the composition of the industrial wastewater leaking from the gold mining “Kuchbulok mine” belonging to the Angren mining department of the Almalyk mining and metallurgical combine was studied through qualitative reactions of the corresponding ions. The pH environment of the water was determined. Based on qualitative reactions, inversion-voltammetric and X-ray-fluorescence quantitative analyzes were carried out.
