Abstract

The invention discloses a method for preparing a parathion molecular imprinting polymer for water quality detection. According to the method, parathion is used as a template molecule to polymerize the parathion molecularly imprinted polymer for organic phosphorus detection in a water environment under the initiation action of ultraviolet light. The parathion molecularly imprinted polymer prepared by the method has the advantages of short polymerization time and favorable adsorbability; and when the prepared parathion molecularly imprinted polymer is used as a solid phase extraction column filler, solid phase extraction-gas phase chromatography can be utilized to quickly and effectively analyze organic phosphorus pesticide in water, and the parathion molecularly imprinted polymer has the advantages of favorable separating effect, less impurity interference, low detection limit, high sensitivity, high precision and favorable recovery effect, and can satisfy the requirements for detecting trace amounts of organic phosphorus in water.

Description

technical field

[0001] The invention relates to a method for preparing a parathion molecularly imprinted polymer, in particular to a method for preparing a parathion molecularly imprinted polymer for water quality detection through photoinitiated polymerization. Background technique

[0002] Organophosphorus is one of the widely used pesticides at present. Organophosphorus is a nerve agent, which can cause poisoning of humans and animals to varying degrees and cause environmental pollution. Long-term drinking of water containing organophosphate can cause human cancer, arteriosclerosis, cardiovascular disease, and fetal malformation. , stillbirth, premature death, premature aging and other diseases. Therefore, it is of great significance to establish a more effective method for the detection of organic phosphorus residues in water. At present, there are many reports on the detection methods of organophosphorus in fruits, vegetables and soil by using organophosphorus molecula...
