SYNTHESIS OF THALLIUM SULPHATE IN A SULFURIC ACID SOLUTION AT POLARIZATION BY CURRENT

Аннотация

Nowadays, the one of the actual problems is the recycling of metal waste and its provision to
consumers. However, it is known that there are a number of difficulties with the recycling of thallium waste. By
using new recycling methods, it's possible to increase thallium resources and lower prices for thallium-derived
products. Therefore, some work was carried out to extract its compounds from thallium waste by studying the
electrochemical properties of thallium in our research work. The experimental results showed that thallium
electrodes dissolve in an aqueous solution of sulfuric acid under alternating current polarization with the formation of
thallium (I) sulfate.
In this work, the kinetics of electrochemical oxidation-reduction of thallium in aqueous solutions of sulfuric
acid is studied by potentiometry. To characterize the mechanism of thallium electrooxidation, the following
parameters were calculated: the order of the reaction and the effective activation energy of the process. The impact of
electrolysis modes: current density, concentration and temperature of the electrolyte on the dimensional characteristics of the obtained thallium (I) sulfate was investigated
