Reduction of the Corrosiveness of Liquid Wastes of the Production of Chlorine and Caustic Soda

  • Published:
Materials Science Aims and scope

On the example of model solutions (simulators), we study the corrosiveness of hypochlorite-containing waste waters prior to and after their interaction with organic waste waters. It is established that, for low concentrations of hypochlorite, it has a higher corrosiveness than tap water. As a result of the addition of simulators of organic waste waters to hypochlorite-containing waters, their corrosiveness decreases to the level of tap water, most likely due to the neutralization of hypochlorite and the formation of the products of oxidation of organic substances with adsorption properties. For strengthening the interaction of hypochlorite with organic compounds and rapid reduction of the corrosiveness of hypochlorite wastes, it is reasonable to intensify the reactions of oxidation by using catalysts and ultrasonic treatment.
