Embodiment Construction

[0011] A citric acid modified activated carbon material, made of the following raw materials in parts by weight (kg): activated carbon 95, citric acid 32, white vinegar 11, calcium chloride 10, silica gel 13, modified attapulgite 9, and an appropriate amount of water;

[0012] The modified attapulgite is made of the following raw materials in parts by weight (kg): attapulgite 110, jade powder 3, kaolin 9, crosslinking agent TAC 1.5, aluminum hydroxide 9, zinc stearate 2, borax 1 , titanium sulfate 16, urotropine 2, lanthanum oxide 1, chromium oxide 3, morpholine 1, and an appropriate amount of water; the preparation method is to send attapulgite, jade powder, and kaolin into a calciner, and calcined at 880°C for 2 hour, take it out, sprinkle with cross-linking agent TAC, then put it into appropriate amount of water for grinding, adjust the pH value of the grinding liquid to 4, grind for 1.5 hours to obtain a 120-mesh slurry, then adjust the pH value of the grinding liquid to be...

Abstract

A citric acid modified activated carbon material is prepared from the following raw materials: by weight, 90-100 parts of activated carbon, 30-34 parts of citric acid, 10-12 parts of white vinegar, 8-12 parts of calcium chloride, 12-14 parts of silica gel, 8-10 parts of modified attapulgite and a moderate amount of water. The citric acid, acetic acid and other acidic raw materials are added to the modified activated carbon, so that on the one hand, tap water becomes weak acidic, and the modified activated carbon has the effects of sterilization, disinfection, face beautifying and skin care, and on the other hand, the adsorption capacity of the activated carbon is maintained for tap water purification; the spray-dried modified attapulgite is added into the modified activated carbon, so that the adsorption effect of the modified activated carbon is stronger; the preparation method of the modified activated carbon is novel in process, is simple and easy, is low in cost, and has important environmental protection properties and excellent market prospects.

Description

technical field [0001] The invention relates to a method for modifying non-metallic minerals, in particular to a citric acid modified activated carbon material and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen of air c...
