Abstract

The invention discloses a chrysanthemum ester molecularly imprinted polymer preparing method and relates to a molecularly imprinted polymer preparing method. The chrysanthemum ester molecularly imprinted polymer preparing method includes the following steps that firstly, chrysanthemum ester type template molecules, styrene, halomethane, a cross-linking agent, a stabilizing agent and an initiating agent are evenly mixed and are stirred at the temperature of 50-80 DEG C after nitrogen leading and aerating; secondly, after a reaction is over, standing and layering are conducted, supernatant is removed, a lower-layer solid is eluted through a carboxylic acid and alcohol mixing solution, and chrysanthemum ester molecularly imprinted polymer powder is obtained. The preparing chrysanthemum ester molecularly imprinted polymer is in a powder form, powder-form polymers are in a microsphere shape, surface hole forming is obvious, the powder-form polymers can be directly used for extracting chrysanthemum ester pesticide residues from food media without being ground, and the recovery rate can reach more than 90 percent. According to the chrysanthemum ester molecularly imprinted polymer preparing method, processing does not need to be conducted again, the preparing process is simple, the technology is stable, and the preparing cost is low.

Description

technical field

[0001] The invention relates to a method for preparing molecularly imprinted polymers, in particular to a method for preparing pyrethroid molecularly imprinted polymers. Background technique

[0002] Pyrethroid pesticides are broad-spectrum insecticides with quick-acting, high-efficiency, low toxicity, low residue, and safety to crops. In addition to having special effects on more than 140 kinds of pests, some pyrethroid pesticides are also effective on underground pests and Acarid pests have a good control effect, therefore, pyrethroid pesticides are widely used in the agricultural field, and pyrethroid pesticide residues are a major problem in today's food health.

[0003] Molecular Imprinting Technology (MIT) is a new technology for the preparation of polymer materials with recognition function that has emerged in recent years. It can obtain molecularly imprinted polymers (molecularly imprinted polymers, MIPs), this technology has been applied to the prep...
