specific Embodiment 1

[0025] Specific embodiment one: the preparation method of this embodiment modified negative oxygen ion powder is implemented according to the following steps:

[0026] 1. Prepare 50-60 mL each of 0.5 mol / L ammonium sulfate solution, barium chloride solution and EDTA solution;

[0027] 2. Under the condition of stirring at room temperature, pour 50-60mL EDTA solution into 50-60mL barium chloride solution, adjust the pH of the system with ammonia water to 6-8, and stir for 20-30min;

[0028] 3. Take another 500mL three-necked bottle, add 5.8-11.6g of negative oxygen ion powder, add the above mixed solution under stirring conditions, and stir for 5-8 minutes to make it evenly mixed;

[0029] 4. Add 50-60mL ammonium sulfate solution dropwise, speed up the stirring, and stir for 30-40min;

[0030] 5. After standing still, wash with deionized water and ethanol for 3 to 5 times, and then dry in an oven at 55 to 65°C to obtain negative oxygen ion powder loaded with nano barium sulfat...

Abstract

The invention discloses a preparation method of modified negative oxygen ion power, belongs to the technical field of chemical engineering and solves the problems that, for instance, existing negativeoxygen ion powder having high polarity and particulate fineness have difficulty of dispersing in non-polar substances, poor apparent properties and high lateral irradiation. The preparation method comprises: I, preparing ammonium sulfate solution, barium chloride solution and EDTA (ethylenediaminetetraacetic acid) solution; II, pouring the EDTA solution into the barium chloride solution under stirring; III, adding the negative oxygen ion powder into the mixed solution above, and mixing well; IV, dropwise adding the ammonium sulfate solution, stirring at higher speed for a period of time; V, allowing standing, centrifugally washing with deionized water and ethanol, and drying to obtain nano barium sulfate particle-supported negative oxygen ion powder. The preparation method is simple, novel and unique and is environmentally friendly, the modified negative ion powder has the original properties as well as those of nano barium sulfate particles, and therefore, the negative oxygen ion powder has better utilization value and a wider range of application.

Description

technical field [0001] The invention relates to a preparation method of modified negative oxygen ion powder, which belongs to the technical field of chemical industry. Background technique [0002] Negative ions are a class of negatively charged ions or ion clusters that exist in the human living environment—the atmosphere. It relies on many methods such as air collision, lightning, radiation, water impact, plant photosynthesis, material tip discharge, etc., which is of great benefit to human health and the quality of the living environment. Therefore, negative air ions enjoy the reputation of "Vitamin Oxygen", "Air Vitamin", "Longevity Supplement" and "Air Vitamin" in the medical field, and they are also one of the important indicators to measure the cleanliness of the air. The research on negative ions is of great significance to human health and the living environment. The effects on human health are mainly reflected in respiratory health care, promoting blood circulatio...
