Title:
USE OF TETRAVINYL SILANE-POLYSTYRENE ADSORBENT IN ANILINE ADSORPTION
Document Type and Number:
WIPO Patent Application WO/2023/035282
Kind Code:
A1
Abstract:
The present invention relates to the use of a tetravinyl silane-polystyrene adsorbent in aniline adsorption, and belongs to the technical field of adsorbent adsorption. The adsorbent is prepared from tetravinyl silane and polystyrene by means of a Friedel-Crafts alkylation reaction, and the amount of aniline adsorbed by the adsorbent is greater than 1300 mg/g. When the adsorbent is placed in a water body, aniline in the water body can be selectively adsorbed, and aniline in wastewater can be quickly removed by means of adsorption.
