Abstract: The invention discloses a preparation method of a carbon quantum dot-molecularly imprinted composite material and a method using carbon quantum dot-molecularly imprinted composite material to analyzeresidues of mesotrione pesticide, and relates to a preparation method of a carbon quantum dot-molecularly imprinted composite material and a method for analyzing mesotrione pesticide. The preparationmethod and the analyzing method aim at solving the problems of long mesotrione analyzing time and low selectivity in the prior art and high cost and large pollution to environment in the synthezing method of the quantum dot molecularly imprinted composite material. The preparation method comprises the following steps of 1, preparing carbon quantum dots; 2, modifying the carbon quantum dots; 3, imprinting molecules, so as to obtain the carbon quantum dot-molecularly imprinted composite material. The analyzing method comprises the following steps of 1, preparing a dispersion liquid; 2, detectingfluorescent intensity of a contrast group; 3, determining quenching constant Ksv; 4, detecting a to-be-detected sample, and calculating the content Qu of the mesotrione in the to-be-detected sample.The analyzing method is mainly used for analyzing the residues of the mesotrione pesticide in an environment water sample.
