Embodiment 1

[0050] Preparation of hydrogel:

[0051] 1) Aluminum isopropoxide and water are mixed in a molar ratio of 1:100 to make an aluminum isopropoxide solution;

[0052] 2) Put the aluminum isopropoxide solution into a three-necked flask and stir at 80°C for 1 hour to allow the aluminum isopropoxide to be hydrolyzed;

[0053] 3) adding nitric acid of 0.1 times the molar weight of aluminum isopropoxide to the solution after the hydrolysis of aluminum isopropoxide;

[0054] 4) Put the above solution into a three-necked flask and reflux and stir at 80° C. for 7 to 8 hours. The solution gradually transitions to a sol and finally to a hydrogel. figure 1 This is a photograph of the resulting hydrogel irradiated with a laser pointer, where the Tyndall effect can be seen.

[0055]Preparation of support body:

[0056] 1) Mix bauxite, 1-methyl-2-pyrrolidone (NMP), polyphenylene ether sulfone (PESF), and polyvinylpyrrolidone (PVP) in a mass ratio of 35:24:4:1 to make bauxite soil layer;

Abstract

The invention relates to a hydrate gel type filter element and a preparation method thereof. The hydrate gel type filter element comprises hydrogel for barrier filtration and a support for supportingthe hydrogel. The hydrogel is metal hydroxide gel, and the support is prepared from metal oxide and nonoxide ceramic materials. The hydrate gel type filter element prepared according to the method isextensively applicable to the field of water purification and capable of effectively removing bacteria and viruses in water and has excellent improving effects on water turbidity and color and excellent removal effects on total organic carbon and the like.

Description

technical field [0001] The invention discloses a preparation method of a hydrate gel type filter element, which belongs to the field of material technology engineering. Background technique [0002] According to the report of the World Health Organization: 1 billion people in the world are drinking polluted water, and 1.8 billion people are sick because of drinking polluted water; 80-90% of the diseases and 33% of the deaths in the world are related to drinking polluted water. water related. Bacteria and microorganisms in water are key factors affecting human health. It can be seen that clean water is very necessary for people's normal and safe life. [0003] At present, most of the water purifiers of mainstream brands on the market, such as Midea, Dalton, 3M, etc., have filter elements made of activated carbon and ceramics. This type of water purifier can effectively remove suspended solid impurities and high-molecular organic matter in water, but it is difficult to effe...
