Abstract

The invention discloses a preparation method of hydrogen storage coral calcium with synergistic oxidation resistance. The preparation method specifically comprises the following steps: mixing CaH2 andzinc particles, dropwise adding dilute sulfuric acid into the mixture, adjusting a dropwise adding speed of the dilute sulfuric acid after the CaH2 is completely reacted, carrying out heating, stirring the materials at constant temperature so that hydrogen is generated in the reaction process, drying the hydrogen, introducing the dried hydrogen into coral calcium, carrying out heating, and continuously reacting to obtain the hydrogen storage coral calcium. The hydrogen storage coral calcium is obtained through hydrogen storage of natural coral calcium, the hydrogen storage coral calcium serves as a hydrogen slow-release material, effective application time can be guaranteed through long-acting action, the use interval can be prolonged, and it can also be guaranteed that trace hydrogen given out through a slow-release path is fully utilized.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and relates to a method for preparing hydrogen-storage coral calcium with synergistic anti-oxidation properties. Background technique [0002] A certain amount of free radicals are produced during the normal metabolic process of the human body. As intermediates of various biochemical reactions, free radicals have high chemical activity due to the presence of unpaired electrons. Under normal conditions, free radicals are essential for maintaining the normal physiological state of the body. However, when the various strong active free radicals produced by various internal or external stimuli are excessive, the oxidation and anti-oxidation effects in the body will be out of balance, which will affect the body. It shows a certain degree of danger, damages the structure and function of biological macromolecules such as proteins and nucleic acids, and then harms human organs. In order to mai...
