Embodiment Construction

[0018] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0019] A method for detecting residues of isoprocarb, characterized in that it comprises the following steps:

[0020] (a) Sampling process: remove a certain amount of rice, wheat or other crops, and use 20g as the basis, carry out crushing treatment to make a treatment liquid, and combine it with a nanomaterial enhancer to make a sample to be tested;

[0021] (b) irradiating the sample to be tested with excitation light and collecting Raman light from the sample to be tested;

[0022] (c) Obtain the Raman spectrum curve of the sample to be tested from the collected Raman light; and compare the Raman spectrum curve with the reference Raman spectrum library of known isoprocarb to determine the isoprocarb in the sample to be tested The concentration of Procarbil residues.

[0023] The Library of Reference Raman Spectra for Known Isoprocarb includes...

Abstract

The invention discloses a detecting method of isoprocarb residue. The detecting method is characterized by comprising the steps of (a) sampling process, to be specific, taking 20 g of rice, wheat or other crops as base, and preparing a processing fluid after crushing; combining with a nanometer material enhancing agent to prepare a sample to be detected; (b) irradiating the sample to be detected with exciting light and collecting Raman light of the sample to be detected. Through the Raman spectrum, the detecting method of isoprocarb residue can detect the composition and concentration of the isoprocarb residue in the sample to be detected. The scheme can efficiently, simply and exactly detect the isoprocarb residue in food (such as fruits and vegetables), and is particularly applicable to the quick detection on site.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method for the residual amount of isoprocarb. Background technique [0002] my country is a large agricultural country, and agriculture plays a decisive role in the national economy and people's lives. Crop diseases, insect pests, weed damage, rodent damage, etc. are the main disasters affecting agricultural production, and the chemical isoprocarb is widely used in the prevention and treatment of crop diseases, insect pests and weeds due to its advantages of quick effect, wide control range, stable properties, convenient storage and transportation, and low price. Rat infestation and eradication of sanitation pests and diseases play a huge role. It is an indispensable and important means of production in modern agricultural production and promotes the development of modern agriculture. [0003] Pesticide residue is a general term for the trace pesticide precursors, toxic metaboli...
