Problems solved by technology

However, due to the low chlorine evolution overpotential and high oxygen evolution overpotential of this electrode, the residual chlorine ions in the water are easily electrolyzed into chlorine gas in the process of electrolyzing water, which remains in drinking water in the form of residual chlorine. This kind of electrolyzed water rich in residual chlorine is not suitable for direct drinking

Abstract

The invention provides a device with a titanium-based gold-plated electrode for generating hydrogen-rich water through electrolysis, and belongs to technical field of electrochemistry. The device comprises an electrolytic tank, a negative electrode, a positive electrode and a controllable electrolytic power supply, wherein the negative electrode, the positive electrode and the controllable electrolytic power supply are put in the electrolytic tank. The negative pole and the positive pole of the controllable electrolytic power supply are connected with the negative electrode and the positive electrode through wires respectively; a stainless steel electrode is adopted as the negative electrode, and the titanium-based gold electrode is adopted as the positive electrode. Compared with an existing DSA positive electrode composed of Ir, Ru, Ti and oxides thereof, by means of the titanium-based gold-plated positive electrode, the quantity of residual chlorine generated in the electrolytic process is significantly decreased.

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to an electrolytic water container. Background technique [0002] Electrolysis of hydrogen-rich water refers to the electrolysis of water into hydrogen and oxygen through electrolysis, and the hydrogen and oxygen produced are dissolved in water to a certain extent, while ordinary drinking water does not contain hydrogen. The hydrogen-rich drinking water obtained in this way is generally called hydrogen-rich water. The unique selective antioxidant function of hydrogen-rich water has attracted more and more attention in terms of health care. In the field of electrolyzed water, especially in the field of drinking electrolyzed water, the water quality requirements after electrolysis are different from those in the general industrial electrolyzed water field. One of the important points is the residual chlorine content of water after electrolysis. Residual chlorine can be divi...
