The invention discloses a 
dye absorption agent and preparation method and application thereof. The 
dye absorption agent is prepared from, by weight, 22-30 parts of 
illite, 3-7 parts of oxidized 
polyethylene, 2-6 parts of 
acetylacetone, 1-5 parts of 
cobalt nitrate, and 9-17 parts of 3-
hydracrylic acid. In the preparation method, the 
illite and oxidized 
polyethylene are blended and grinded, 3- 
hydracrylic acid, 
acetylacetone and 
cobalt nitrate are used in the treatment, 
dye absorption agent is prepared through 
ultrasound irradiation; the dye absorption agent absorbs heavy 
metal, different types of dyes as well as other organic 
pollutant, has strong adsorption ability for dye material, is non-toxic for human, is non-corrosive, has stable performance, cleans easily, causes no second time 
pollution to water. The dye absorption agent prepares and operates easily, the cost of the dye absorption agent is low, the efficiency of absorption is high; the dye absorption agent is 
environmentally friendly, facilitates industrialization production, suits for treating all the 
wastewater polluted by organic dyes, including direct scarlet, cationic 
brilliant red, acid brilliant scarlet, 
methylthionine chloride, 
neutral red, viola crystallina, helianthin B and other organic dyes.
