Mathematical modeling of the sulfuric acid concentration process’ kinetics in electrochemical treatment of sulphate-containing eluates

The research exposes results obtained in sulphate-containing eluates electrochemical treatment using two-chamber anion exchange membrane MA-41electrolyzer. It is shown that the concentration of sulfuric acid can be increased by electrolysis up to 40%. The research included study of current voltage influencing the process’ effectiveness. The heterogeneous processes mathematical models at Delphi 7 environment are used to calculate the kinetic parameters of sulfuric acid solutions electrochemical processing using two-chamber electrolyzer divided with anionic membrane MA-41 into two sections. Based on the calculated rate constants, pre-exponential factor and activation energy authors obtained the Arrhenius equation
