Abstract
In this paper we investigated the graphite anodes in the electrolysis of aqueous solutions.
We examined the effects of current density, of temperature, and of concentration of electrolyte on the consumption of carbon electrodes in the forms of gas and of sludge.
In the electrolysis of solutions of sulphuric acid, or sulphates over wide range of H+ ion concentrations, we found that the consumption of carbon both as CO2 or CO and as sludge was far greater in the presence of sulphate ionthan in the absence of it, and that remarkable amount of CO, the ratio of which to CO2 was 0.12-0.15, evolved. But in the electrolysis of brine, even the presence of 6/10 N SO4 did not seem to have such effects.
