Abstract

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.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a dye adsorbent and its preparation method and application. Background technique [0002] Dyes are substances that can color fibers and other materials, and are widely used in the dyeing and printing of textiles, paints, plastics, paper and leather manufacturing. Due to the large amount of wastewater generated during the use of dyes, these wastewaters still contain a certain amount of dye substances, which must be treated before they can be discharged. The treatment of dye wastewater usually includes adsorption method, coagulation method, redox method, biochemical method and membrane treatment method. Although these methods can reduce the dye content in dye wastewater to a certain extent, there are still various defects, for example, due to low adsorption rate, high treatment cost and poor adaptability to changes in the composition of dye wastewater, t...
