Preparation of hydrophilic acrylic adsorption resin and application of acrylic adsorption resin in phenolic wastewater treatment

Abstract

The invention relates to preparation of hydrophilic acrylic adsorption resin and an application of the acrylic adsorption resin in phenolic wastewater treatment, and belongs to the technical field of the preparation and the application of high molecular material absorption resin. The preparation method comprises the following steps: dissolving polyvinyl alcohol in the water liquid of sodium chloride so as to form an aqueous phase; and forming an oil phase by a pore-forming agent and an initiating agent, namely benzoyl peroxide, by taking acrylate and benzene sulfonate containing carbon-carbon double bond as monomers and taking ethylene glycol dimethacrylate as a cross-linking agent, adding the oil phase to the aqueous phase and carrying out a thermal insulating reaction so as to obtain resin. The mole ratio of the carbon-carbon double bonds of two monomers, namely the acrylate and the benzene sulfonate, is controlled within the range of (4:1)-(8:1), the volume ratio of the oil to the water is controlled at 1: 5, the sodium chloride accounts for 5% in terms of the mass of distilled water, and the polyvinyl alcohol, the ethylene glycol dimethacrylate, the pore-forming agent and the benzoyl peroxide respectively account for 3-5wt%, 4-6wt%, 40-60wt% and 2wt% of the total mass of the reactant. The preparation disclosed by the invention is simple in process; and the preparation lays a foundation for the treatment of phenolic wastewater by virtue of the adsorption resin, so that the preparation has certain practical significance to popularize.

Description

technical field [0001] The invention relates to the preparation of a hydrophilic acrylate adsorption resin and its application in treating phenol wastewater, and belongs to the technical field of preparation and application of porous adsorption resins of polymer materials. Background technique [0002] Adsorption resin as a polymer adsorbent has been widely used in different fields since it was developed and applied in the 1960s. Because of its good adsorption selectivity, long service life and easy regeneration, it has been widely used in environmental protection. Applications. As an important chemical raw material, phenol is widely used in dyestuffs, agriculture, medicine, military industry and other industries. At the same time, a large amount of phenolic organic pollutants will be produced in the industrial production process. At present, the most effective way to deal with these organic pollutants is to use adsorption resins for adsorption. The commercialized acrylate ...

Problems solved by technology

However, phenol is not only soluble in organic solvents, but also well soluble in water environments. When the phenol content in water reaches 5-10mg / L, it will cause a large number of fish to die; Liver detoxification directly enters the blood circulation, causing damage to human cells

Due to the poor hydrophilicity of the existing acrylate porous adsorption resin, it cannot effectively contact with phenol in the aqueous solution, resulting in unsatisfactory adsorption effect
