Embodiment Construction

[0010] An iron oxyhydroxide modified activated carbon desulfurizer is characterized in that it is made of the following raw materials in parts by weight: activated carbon 120, iron oxyhydroxide 13, sulfate lignin 5, polyvinyl alcohol 5, modified attapulgite 9, water Appropriate amount;

[0011] 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 gr...

Abstract

The invention relates to an iron oxyhydroxide modified active carbon desulfurizer which is prepared from the following raw materials in parts by weight: 120-130 parts of active carbon, 12-14 parts of iron oxyhydroxide, 4-5 parts of lignin sulfate, 4-5 parts of polyvinyl alcohol, 8-10 parts of modified attapulgite and an appropriate amount of water. According to the iron oxyhydroxide modified active carbon desulfurizer disclosed by the invention, the iron oxyhydroxide is used to efficiently desulfurate and dechlorinate, and the desulfuration effect is long in lasting time. The lignin sulfate is further used, so that raw materials such as active carbon can be uniformly dispersed in water. Therefore, the desulfurizer has a better water treatment effect, free from toxic substances and low in production cost, and can be repeatedly and recycled, thereby not only saving the industrial cost, but also laying a foundation for industrial application.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to an iron oxyhydroxide modified activated carbon desulfurizer 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 ...
