Abstract

The invention discloses an application of citric acid in preparation of weak-acid electrolyzed water and a preparation method of the weak-acid electrolyzed water. The preparation method comprises the steps that a citric acid solution and a sodium chloride solution are mixed, so that a mixed solution is obtained; and the mixed solution is subjected to electrolysis, so that the weak-acid electrolyzed water is obtained. By means of the application and the preparation method, the problems that caustic diluted hydrochloric acid exists in an electrolyte solution due to incomplete electrolysis of the diluted hydrochloric acid, and the weak-acid electrolyzed water with the diluted hydrochloric acid serving as an additive is not easy to control due to the fact that the pH changes excessively fast during preparation are solved.

Description

Technical field [0001] The invention belongs to the field of electric potential water sterilization, and specifically relates to an application of citric acid in preparing weakly acidic electric potential water and a preparation method of weakly acidic electric potential water. Background technique [0002] Through a lot of research and practice, it has been found that electrolyzed water is widely used in medical, food and other fields because of its high-efficiency sterilization ability, safe and simple production and use methods, low residue and non-toxic side effects. Among them, the potential water is strong acid potential water, weak acid potential water and alkaline potential water. [0003] For example, the Chinese invention patent application document with publication number CN102616895A discloses an acidic oxidizing potential water, which includes unit A and unit B separately packed before use, the unit A is an acid solution; the unit B is an available chlorine reagent.
