METHOD AND APPARATUS FOR PURIFICATION OF AQUEOUS ZINC SULPHATE SOLUTION IN ELECTROLYTICAL PRODUCTION OF ZINC |
摘要 |
<p>A method and apparatus for determining the purity of a purified zinc sulphate solution used for the electrolytic production of zinc, which are based on the finding that the purity of the purified electrolyte has a fixed relationship with the ratio between the amount of hydrogen gas and the amount of oxygen gas generated by electrolysis of the purified electrolyte. According to the method and apparatus, a mixture of hydrogen gas and oxygen gas generated by the electrolysis of the purified zinc sulphate solution is charged in a combustion chamber of predetermined vellum and ignited by a heater to ignite the hydrogen gas, and the difference between the internal pressures of the combustion chamber before and after the combustion of the hydrogen gas is detected for measuring the hydrogen gas content in the gas mixture.</p> |
