Abstract

The invention discloses a granular adsorbent for adsorbing aniline and a preparation method of the granular adsorbent. Mixed solution B is prepared from 1,4-butanediol, 4-acetamido-3-nitrobenzoic acid, N,N-dimethylformamide, polyvinyl chloride and N-cyclohexyl-2-benzothiazole sulfonamide. Mixed solution D is prepared from polystyrene, N,N-dimethyl formamide and K2HPO4. Mixed solution F is prepared from benzoyl peroxide, chloroform, N-methylformamide, NaNO3 and calcium chloride. Mixed solution H is prepared from the mixed solution B, the mixed solution D, the mixed solution F, methyl isobutyrate, polyethylene glycol and chloroform and dripped into polyvinyl alcohol solution with the mass fraction of 6.6% to obtain mixed solution I. The polyvinyl alcohol solution with the mass fraction of 0.9% is added into the mixed solution I, stirred for 7-8 hours, washed and freeze-dried, and the granular adsorbent for adsorbing the aniline can be obtained.

Description

technical field [0001] The invention belongs to the technical field of organic industrial wastewater treatment, in particular to a particle adsorbent for adsorbing aniline 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 adsorbing org...
