Abstract

A zirconium oxide modified activated carbon adsorbent for removing phosphates is prepared from the following raw materials: by weight, 100-120 parts of activated carbon, 3-4 parts of zirconium n-propoxide, 5-6 parts of sodium tripolyphosphate, 3-4 parts of sodium alginate, 1-2 parts of polyethylene terephthalate, 3-4 parts of octadecyl trimethyl ammonium chloride, 8-10 parts of modified attapulgite and a proper amount of water. The zirconium oxide modified activated carbon adsorbent using the zirconium n-propoxide for modification of the activated carbon can be applied to adsorption removal of the phosphates in water bodies, and has a strong adsorption property; the polyethylene terephthalate and other additives are also added to make the activated carbon be uniformly and stably dispersed in the water, thereby the adsorption effect is better; the zirconium oxide modified activated carbon adsorbent has the advantages of simple preparation, easily obtained materials, simple operation, obvious treatment effect, and good economic and environmental benefits.

Description

technical field [0001] The invention relates to a method for modifying non-metallic minerals, in particular to a zirconia modified activated carbon dephosphate adsorbent 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 scree...
