Embodiment Construction

[0015] The invention utilizes the reduction characteristic of hydrogen and the working principle of the redox potentiometer to establish the connection between the redox potential value and the hydrogen concentration, thereby using the simple and easy-to-obtain redox potentiometer to calibrate the hydrogen concentration of the hydrogen-rich water. The measurement results of the oxidation-reduction potentiometer reflect the macroscopic oxidation-reduction properties of all substances in the solution. A positive value of the potential indicates that the solution shows a certain degree of oxidation, and a negative value indicates that the solution shows reduction. Larger, the stronger the oxidizing property, and the greater the negative potential value, the stronger the reducing property.

[0016] The specific implementation is as follows:

[0017] 1. Redox potentiometer preparation: Redox potentiometers include desktop redox potentiometers, pen redox potentiometers and industria...

Abstract

The invention relates to a method for calibrating hydrogen concentration of hydrogen-rich water by redox potential and belongs to the technical field of hydrogen water. The method is characterized by comprising the following steps: preparing hydrogen-rich water, controlling hydrogen addition amount and preparation time, discontinuously operating and preparing a series of standard samples from low hydrogen content to high hydrogen content; dividing each standard sample into two parts, and measuring a redox potential value of one standard sample by a redox potentiometer; carrying out titration by a titrant, calculating actual hydrogen concentration, repeating the above process to obtain correspondence between hydrogen concentration of hydrogen-rich water and the redox potential value, and drawing a curve chart of the correspondence between the hydrogen concentration of hydrogen-rich water and the redox potential value. A potential value of hydrogen-rich water with unknown hydrogen concentration can be measured by the use of a redox potentiometer, so as to calibrate concentration of hydrogen in water. The method of the invention is a calibration method which has advantages of simple equipment, convenient operation, reliable data and low cost. The method can be widely applied in calibration of hydrogen concentration of hydrogen-rich water.

Description

technical field [0001] The invention relates to a method for calibrating hydrogen concentration in hydrogen-rich water by oxidation-reduction potential, and belongs to the technical field of hydrogen water. Background technique [0002] Hydrogen-rich water, as the name implies, is water rich in hydrogen. Studies have shown that hydrogen has a selective antioxidant effect, and hydrogen can actively choose to combine with peroxyl radicals that are harmful to organisms. The medical community generally believes that peroxide free radicals are one of the root causes of disease and aging, which completely overturns the traditional concept that hydrogen is a physiologically inert gas, provides a treatment method for diseases caused by oxidative damage, and is more important for the prevention of human diseases. The occurrence and aging of the disease provides a preventive measure. [0003] Because hydrogen is flammable, explosive, difficult to liquefy, and inconvenient to store a...
