Abstract: The disclosure discloses a nicotinamide dummy template surface molecularly imprinted polymer, a preparation method and application thereof, and belongs to the technical field of chemical materials. The preparation method of the disclosure includes the steps of preparing a modified silica gel carrier, preparing a dummy template surface molecularly imprinted polymer and the like. The disclosure uses nicotinamide, a structural analogue of imidacloprid and acetamiprid, as a dummy template to prepare a silica gel surface molecularly imprinted polymer. The polymer not only can effectively avoid pollution caused by the leakage of template molecules, but also can specifically remove imidacloprid and acetamiprid from water-soluble tea extracts. The removal rate of imidacloprid and acetamiprid is greater than 96% and 93%, respectively, and the loss of tea polyphenols in the extracts is less than 10%. In addition, the molecularly imprinted adsorption column prepared by the disclosure can be eluted with ethanol solution, and the eluted adsorption column can be recycled, so the disclosure can be well applied to the preparation technology of tea extracts and has good application prospects.

Abstract: A process for producing functionalized activated carbon product includes creating grafting sites on a surface of an activated carbon product, to yield a precursor activated carbon product; exposing the precursor activated carbon product to at least a first vinyl monomer; and initiating a polymerization reaction to graft at least the first vinyl monomer to the grafting sites and polymerize the first vinyl monomer to yield the functionalized activated carbon product. A functionalized activated carbon product includes an activated carbon product having a surface and at least a first polymer grafted to the surface. A process for removing contaminants from water includes adding a functionalized activated carbon product to contaminated water, wherein the functionalized activated carbon product includes an activated carbon product having a surface and at least a first polymer grafted to the surface; and allowing the functionalized activated carbon product to adsorb contaminants from the contaminated water.

Abstract: A method of synthesizing a clay-polyacrylate composite. An aqueous solution including clay is mixed with at least one organosilane coupling agent including an acrylate moiety to form a silanized-clay suspension. The silanized-clay suspension is contacted with a first acrylate monomer and a second acrylate monomer in an inert environment, where the first acrylate monomer and the second acrylate monomer have different solubility. A polymerization initiator is added to the silanized-clay suspension before or during the contacting of the silanized-clay suspension with the first acrylate monomer and the second acrylate monomer in the inert environment to form the clay-polyacrylate composite including the first and second acrylate monomer, where the first acrylate monomer is a hydrophilic acrylate monomer including a hydroxyl (—OH) group and the second acrylate monomer is a hydrophobic acrylate monomer which repels water.
