Abstract

The invention discloses a granular adsorbent for adsorbing carbazole and its preparation method. The granular adsorbent for absorbing carbazole is prepared by preparing 2-piperidone, 4-(1H-Imidazol-1-yl)benzoic acid, milliliter N,N-dimethylformamide, polyvinyl acetate, and 2-mercaptobenzothiazole to be mixed liquor B; preparing polyisoprene nitrile, N,N-dimethylformamide, 2,4-dimethyl quinolone-3-carboxylic acid ethyl ester to be mixed liquor D; preparing dibenzoyl peroxide, chloroform, N-hydroxy-isobutyramide, KNO3, and calcium chloride to be mixed liquor F; preparing the mixed liquor B, the mixed liquor D, the mixed liquor F, methyl isobutyrate, polyethylene glycol, and chloroform to be mixed liquor H; dropwise adding the mixed liquor H to a polyvinyl alcohol solution with the concentration of 6.1wt%, and obtaining mixed liquor I; adding a polyvinyl alcohol solution with the concentration of 1.2wt% to the mixed liquor I, and separating, washing, freezing and drying it after stirring for 7-8 hours.

Description

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