Abstract

A preparation method of a magnetic polystyrene-based bentonite composite adsorbent comprises the following steps: step (1), hydroxyl calcium phosphate and sodium dodecylbenzenesulphonate are added towater, an initiator is added, the substances are stirred, and a styrene monomer is added; an aqueous persulfate solution is added, the mixed solution is heated to 80 DEG C and stirred for a reaction for 30 h, then centrifugal separation is performed, solid substances are reserved, washed with water, processed by ultrasound and dried, and white solids are obtained and are polystyrene microspheres;(2) the polystyrene microspheres prepared in step (1) are dispersed in deionized water, Fe(NO3)3 and Fe(NO3)2 are added under N2 protection, stirring is performed, ammonium hydroxide is added, stirring is continued, and magnetic polystyrene microspheres are obtained; (3) bentonite is added to deionized water, the magnetic polystyrene microspheres prepared in step (2) are added dropwise to the aqueous bentonite solution and stirred, glutaraldehyde is added for crosslinking reaction, then separation and washing are performed, and bentonite composited with magnetic polystyrene is obtained.

Description

technical field [0001] The present application relates to a method for preparing an adsorbent, in particular to a method for preparing a magnetic polystyrene-based bentonite composite adsorbent. Background technique [0002] With the improvement of industrialization and urbanization, the discharge of a large amount of industrial sewage and domestic sewage has polluted the water body and destroyed the ecology. If it is discharged into the ground water without treatment, it will pollute the rivers and lakes, which will seriously harm Industrial and agricultural production and human health. However, the existing sewage treatment agents cannot effectively purify the impurities and chemical components in the sewage, and the purified water quality cannot be effectively guaranteed. [0003] The invention prepares a magnetic polystyrene-based bentonite composite adsorbent, which can be used in a relatively large pH range and can effectively remove copper ions in water.
