Abstract

The invention discloses a function board for adsorbing nitrobenzene and a preparation method thereof. The method comprises the steps that 4-hydroxybutyraldehyde, 4-acetamido-3-nitrobenzoic acid, N,N-dimethylformamide, polypropylene and dibenzothiazyl disulfide are adopted for preparing a mixed solution B; polyacrylonitrile, N,N-dimethylformamide, Na2HPO4 and Mg(NO3)2 are adopted for preparing a mixed solution D; acetonyl acetate, chloroform and ferric chloride are adopted for preparing a mixed solution F; the mixed solution, B, the mixed solution D, the mixed solution F, methyl isobutyrate, polyethylene glycol and chloroform are adopted for preparing a mixed solution H; distilled water is sprayed into a container containing liquid nitrogen to prepare ice-ball particles, and the ice-ball particles with the particle size being 50-100 micrometers are placed into a cavity of a mold to be compacted; then, the mixed solution H is poured into the mold and subjected to freezing and sizing in liquid nitrogen for 6 h, and the function board for adsorbing nitrobenzene is obtained after chloroform and ice-ball particles are removed through vacuum freeze drying.

Description

technical field [0001] The invention belongs to the technical field of organic industrial waste water treatment, in particular to a functional plate for absorbing nitrobenzene 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...
