Abstract
PURPOSE: To remove impurities in a zinc chloride solution efficiently without employing new impurities by a method wherein H2O2 is added to a zinc chloride solution containing iron impurities, heated and iron is oxidized and let cohere.
CONSTITUTION: The first iron is changed into the second iron, which is insoluble to water, by adding hydrogen peroxide water containing H2O2, which is equivalent mol or slightly excessive to iron, to a zinc chloride solution containing iron impurities, a reaction liquid is heated at 60W95°C as it is or after it is neutralized to approximate pH4W5 by NaOH, and ferric hydroxide is let cohere and separated. The filtering capacity of the condensate is excellent.
