Abstract

The invention discloses a function board for adsorbing parathion-methyl, and a preparation method of function board. The preparation method comprises the following steps: preparing mixed liquid B from tetrahydrothiophene, 4-acetamido-3-nitrobenzoic acid, N,N-dimethyl formamide, polyhexamethylene adipamide and hexamethylenetetramine; preparing mixed liquid D from polyvinyl chloride, N,N-dimethyl formamide, 1-(3-pyridyl)-3-(dimethylamino)-2-propylene-1-ketone; preparing mixed liquid F from tert-butyl peracetate, chloroform and N,N-dimethyl glycinamide; preparing mixed liquid H from the mixed liquid B, the mixed liquid D, the mixed liquid F, methyl isobutyrate, polyethylene glycol and chloroform; ejecting distilled water into a container with liquid nitrogen to prepare ice ball particles, and putting the ice ball particles with the particle size being 50 to 100 microns into a mold cavity of a mold, and performing compaction; and pouring the mixed liquid H into the mold, freezing and shaping the mold in the liquid nitrogen for 6 hours, and removing the chloroform and the ice ball particles through vacuum freeze drying to obtain the function board for adsorbing the parathion-methyl.

Description

technical field [0001] The invention belongs to the technical field of organic industrial wastewater treatment, and in particular relates to a functional plate for adsorbing methyl parathion 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 material...
