Abstract

The invention discloses a particle adsorption agent for indole adsorption and a preparation method thereof. Dihydroxy ketone aldolactol, 5-formylindole, N, N-dimethylformamide, polyvinyl alcohol and melaniline are prepared into a mixed solution B; polyvinyl acetate, N, N-dimethylformamide and 4,6-dichloro-5-pyrimidinecarboxaldehyde are prepared into a mixed solution D; peracetic acid tert-butyl ester, chloroform and isobutyramide are prepared into a mixed solution F; the mixed solution B, the mixed solution D, the mixed solution F, methyl isobutyrate, polyethylene glycol and chloroform are made into a mixed solution H; the mixed solution H is dripped into a polyvinyl alcohol solution with the mass percentage of 6.8 percent to obtain a mixed solution I; the polyvinyl alcohol solution with the mass percentage of 0.9 percent is added into the mixed solution I; stirring is performed for 7 to 8h; then, separation, washing and freeze drying are performed; the particle adsorption agent for indole adsorption can be obtained.

Description

technical field [0001] The invention belongs to the technical field of organic industrial wastewater treatment, and in particular relates to a particle adsorbent for adsorbing indole and a preparation method thereof. Background technique [0002] The adsorption method is to mix the adsorbent with the wastewater to be treated, one or several pollutants in the wastewater are adsorbed, and some pollutants can be recovered or removed, so that the wastewater can be purified. This method is suitable for high-concentration organic wastewater. It has a good treatment effect and plays an important role in the organic industrial wastewater treatment technology. The general characteristics of the adsorbent with excellent performance in the adsorption method: good pore structure, excellent surface chemical properties; strong adsorption capacity for adsorbate; easy analysis, strong reusability; good mechanical strength, etc. At present, the most commonly used adsorption materials for ad...
