Abstract

The invention relates to the technical field of antibacterial adsorption materials, and discloses an antibacterial Zn complex-porous resin composite adsorption material and a preparation method thereof. The composite adsorption material comprises the following formula raw materials: an inorganic porous adsorbent, an antibacterial Zn complex, styrene, divinylbenzene, benzoyl peroxide, gelatin and aconcentrated sulfuric acid solution. According to the antibacterial Zn complex-porous resin composite adsorption material and the preparation method thereof, in crystal structure defects of calcium carbonate modified diopside and calcium compound doped diopside, diopside crystals form numerous complicated pore structures and regular stripe lines; the inorganic porous material formed by calciningcan well adsorb pollutants; sulfonated poly(styrene-divinylbenzene) enables Ca<2+>, Mg<2+> and other cations to be subjected to exchange reaction; Zn complexes, namely, Zn-aminated biphenyl salicylaldehyde are uniformly loaded in the pore structures of the sulfonated poly(styrene-divinylbenzene); and central metal Zn<2+> ions and active substituent groups on benzene rings have an obvious inhibiting effect on escherichia coli and pathogens in tap water.

Description

technical field [0001] The invention relates to the technical field of antibacterial adsorption materials, in particular to an antibacterial Zn complex-porous resin composite adsorption material and a preparation method thereof. Background technique [0002] Tap water pollution refers to that in daily life, the tap water treated by the water plant needs to go through a long water delivery network, water towers, water tanks and other facilities. During these transmission processes, many pollutants are added to the tap water, such as residual chlorine and rust. Pollutants such as pollutants, dirt, bacteria and microorganisms directly affect the water quality of tap water, and these pollutants interact to produce more toxic chemicals. [0003] At present, the common tap water purification materials on the market mainly include polypropylene fiber materials, activated carbon adsorption materials, softening resin materials, copper-zinc alloy materials, etc., but polypropylene fib...
