Abstract

The invention discloses high-concentration negative oxygen ion powder and a preparation method thereof, belonging to the technical field of environment-friendly material processing. The preparation method of the high-concentration negative oxygen ion powder comprises the following steps: 1) adding raw stone powder into a calcium suspension, carrying out uniform mixing, and then introducing carbondioxide gas for a reaction for 30-50 seconds to obtain an acidification system, wherein the calcium suspension is a calcium hydroxide suspension; 2) adding a crystal form regulator and a catalytic substance into the acidification system obtained in the step 1), carrying out uniform mixing, and introducing carbon dioxide for 10-15 minutes to obtain a regulation system, wherein the catalytic substance is an Au / TiO2 composite catalyst or is composed of a gold source and a titanium source; and 3) adding a dispersing agent into the regulation system obtained in the step 2), carrying out uniform mixing to obtain a homodisperse system, carrying out solid-liquid separation, and conducting drying to obtain the high-concentration negative oxygen ion powder. The prepared high-concentration negative oxygen ion powder is capable of releasing negative oxygen ions with higher concentration.

Description

technical field [0001] The invention relates to the technical field of environmental protection material processing, in particular to a high-concentration negative oxygen ion powder and a preparation method thereof. Background technique [0002] Some natural ores can produce negative ions under certain conditions and are widely used by people. Negative ions are also called negative oxygen ions, which refer to negatively charged oxygen ions that obtain excess electrons. Negative oxygen ions are divided into three types according to their migration distance and particle size: large, medium and small. Among them, the most beneficial to the human body is the small ion, also known as light ion, which has good biological activity. When the standard concentration of light ions in a unit space is higher, people will feel that the air here is fresher. Studies have shown that negative oxygen ions can affect the physiological activities of the human body through the human nervous syst...
