Abstract

The invention relates to a preparation method of a triazine phytocide molecular imprinting solid phase extracting material. The method comprises the following steps of: 1. dissolving butyltripolycyanamide, alpha-methacrylic acid, glycol di(methacrylic acid)ester and azodiisobutyronitrile into trichloromethane and uniformly mixing to obtain a suspending phase I; 2. dissolving polyvinyl alcohol 1788 into water to obtain a suspending phase II; and 3. stirring and reacting the suspending phase I with the suspending phase II and drying in vacuum to obtain the triazine phytocide molecular imprinting solid phase extracting material. In the invention, by adopting a substituted molecular template, the imprinting effect is ensured and the problem of template seepage is solved; the optimized use condition is more convenient for solid phase extraction and ensures favorable impurity removing function and favorable repeatability; the matrix effect is remarkably weakened; and the triazine phytocide molecular imprinting solid phase extracting material is better than the traditional main stream solid phase extracting product, not only can ensure the detecting accuracy but also can improve the detecting sensitivity and effectively protect a chromatographic column.

Description

technical field

[0001] The invention belongs to the technical field of analysis and determination of triazine herbicide residues, and in particular relates to the preparation and application of pretreatment materials in the analysis and determination of triazine herbicide residues. technical background

[0002] At present, with the development of my country's agricultural modernization and the gradual transfer of agricultural labor to cities, cultivation and farming methods tend to be large-scale and intensive, and the demand for agricultural production has increased significantly. Among them, the growth rate of herbicides in recent years is much higher than the development level of insecticides and fungicides. The wide use of herbicides in my country has brought positive benefits such as agricultural modernization and crop yield growth, but it has also caused weed resistance in the field. It is becoming more and more serious, and in turn induces a further increase in the app...
