Embodiment Construction
[0010] A dogwood fruit stone modified activated carbon water purifier, made of the following raw materials in parts by weight (kg): dogwood fruit stone 55, calcined gypsum 11, dry alum 5, lignocellulose 13, calcium-based montmorillonite 7, milk Protein 4, acrylonitrile 9, ammonium persulfate 1.4, activated carbon 104, gelatin 8, chitosan 11, modified diatomite 4, water in proper amount;
[0011] The modified diatomite is made of the following raw materials in parts by weight (kg): 145 diatomite, 11 alum, 1.5 nano-carbon, 1.5 barley oil, 2.5 ascorbic acid, 1.6 citric acid, 2.4 sodium tripolyphosphate, ginseng powder 2.4; the preparation method is to put the diatomite in a calciner and calcinate at 550°C for 3.6 hours, take it out, soak it in 13% hydrochloric acid solution for 4.5 hours, filter it out, wash it repeatedly with clean water, dry it, add it to water, At the same time, add nano-carbon, ascorbic acid, citric acid and alum, grind to obtain a slurry, spray dry, mix othe...

Abstract
The invention relates to a dogwood kernel modified active carbon water purifier, which is prepared from the following raw materials in parts by weight: 50 to 60 parts of dogwood kernel, 9 to 12 parts of calcined gypsum, 5 to 6 parts of dried alum, 10 to 15 parts of lignocellulose, 6 to 9 parts of calcium-based montmorillonite, 3 to 5 parts of milk protein, 8 to 10 parts of acrylonitrile, 1 to 2 parts of ammonium persulfate, 100 to 110 parts of active carbon, 7 to 9 parts of gelatin, 10 to 13 parts of chitosan, 4 to 5 parts of modified diatomite and an appropriate amount of water. After the dogwood kernel is carbonized at a high temperature, a structure with multiple pores and strong adsorption capacity is formed, so that the cost is saved and the environmental pollution is reduced; due to use of the macromolecular compounds such as acrylonitrile, gelatin, lignocellulose and chitosan and the like, the adhesive force can be increased, the disintegration is unlikely to happen, an effect of chelating metal ions can be realized, and safe and non-toxic effects are achieved; due to use of calclium-based montmorillonite, an antibacterial function, a deodorizing function and an ion exchanging function can be achieved; due to use of the calcined gypsum and the dried alum, a sterilizing function can be achieved; the dogwood kernel modified active carbon water purifier is safe, healthy, low in cost and particularly suitable for water purification.
Description
technical field [0001] The invention relates to the field of modified functional materials, in particular to a dogwood fruit stone modified activated carbon water purifier and a preparation method thereof. Background technique [0002] At present, air pollution has seriously affected people's production and life, so air purification has to be taken seriously. Adsorbents are often used in air purification, mainly activated alumina, activated carbon, and adsorption materials developed for selective adsorption of certain components. However, most of these adsorbents have limited adsorption capacity, and different adsorbents need to be studied according to different requirements to play the best role. At the same time, look for new raw materials to enhance the adsorption effect and save costs. With the continuous improvement of people's requirements for quality of life, it is also necessary to provide adsorbents that are beneficial to the human body. Contents of the inventio...
