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.
