Big residual quantity is 1mg/kg.
Method is analyzed in Pesticides Testing at present mainly to be had: chromatography, inhibiting AChE, immunological method, chemoluminescence method etc..Color
Spectrometry is the method for the most commonly used detection pesticide, owing in general institute test sample product, impurity is more, is easily subject to interference, generally exists
Need before analysis sample is carried out pre-treatment, improve accuracy and the sensitivity of method.The sensitivity of inhibiting AChE is general
Poor, repetitive rate, the response rate are relatively low, and the sensitivity to different pesticide is different, so applying in general to the quick detection at scene
And the selective mechanisms of gross sample.The selectivity of reagent is required higher by immunological method, needs synthesis in advance relatively during detection
The artificial antigen answered.The most single workload of haptenic synthesis is big, the cycle is long, and pesticide that may be similar with pesticide structure to be measured
Or there is cross reaction in various degree in pesticide metabolism thing to be measured.The selectivity of chemoluminescence method detection is poor, and most
Analysis sample composition is complicated, so being generally combined with isolation technics by chemiluminescence, to reach ideal effect.Therefore, build
Vertical a kind of high sensitivity and the method for specific Rapid Screening pesticide residue, become and need solution badly for this research field current
One of problem.
Metal-organic framework material, is that a class has high porosity, high-specific surface area, the adjustable compound of structure, utilizes
Its character advantage binding molecule blotting membrane material can improve adsorbance.Molecular engram sensitive material and biological sensitive materials are as raw
Thing enzyme, antigen-antibody etc. are compared, and not only have high temperature resistant, high pressure, organic solvent, acid, alkali etc., and can be repeated several times and make
With;Molecularly imprinted polymer material has high selectivity, a high adsorption to target molecule simultaneously, and therefore it compares and is suitable as electricity
The sensitive material of chemical sensor, is assembled into the electrochemical sensor of molecular engram.Additionally, with conventional and traditional sensory device
Material is compared, and it has preferable selectivity, good stability to target compound, is passed as electrochemistry by molecular engram material
The sensing unit of sensor, is then converted into by electrochemical means and can measure the signal of telecommunication, can be used for high selection quantitative analysis acetyl
Bayer 71628 material.
