Abstract
The article deals with the process of electrochemical dissolution of zinc polarization by alternating current of 50 Hz frequency in a solution of sodium sulfate. The influence of various parameters on the current efficiency of zinc dissolution was considered: the current density on the titanium and zinc electrodes, electrolyte concentration, duration of electrolysis and temperature of electrolyte. It was shown that at change of current density on the titanium electrode from 10 kA/m2 up to 70 kA/m2 current efficiency of zinc dissolution increases (55%), and further down. At change of current density of zinc electrode from 200 A/m2 to 800 A/m2, electrolysis time from 0.25 to 2.0 hours and increase of temperature from 20°C to 80°C the current efficiency of dissolution decreases and with increasing concentrations of sodium sulphate increases to 90%. Based on the results shown it is possible to create a waste-free synthesis of zinc compounds from environmental harmful residues of zinc metal by electrochemical technology.
