Embodiment Construction

[0014] In the present invention, the described can provide I - Ions, S 2- Ion or F - Ionic substances preferably contain I - Ions, S 2- Ion or F - The salt of ions, further preferably containing I - Ions, S 2- Ion or F - Inorganic salts of ions, particularly preferably containing I - Inorganic salts of ions, such as KI, NaI, MgI 2 、CuI 2 or FeI 2 Wait.

[0015] In a preferred embodiment, in the kit according to the present invention, the said can provide I - Ions, S 2- Ion or F - Salts of ions can exist in solution or in solid form. When it exists in solid form, it can be directly added to the liquid sample to be tested, or it can be dissolved in water before use.

[0016] In another preferred embodiment, in the kit of the present invention, the said can provide I - Ions, S 2- Ion or F - Ionic substances can also be capable of producing I - Ions, S 2- Ion or F - The chemical raw materials of ions, when used, first mix the raw materials and then react to pr...

Abstract

The invention belongs to the field of analytical chemistry, and relates to a method and a kit for quickly detecting paraquat and / or diquat. The method includes the step of mixing a to-be-tested sample(the to-be-tested sample is a non-pretreated sample or a pretreated sample)with gold nanoparticles and a material capability of providing I<->, S< 2-> or F<->, and a surface enhanced Raman spectroscopy analysis method is used for detection. The method can quickly detect paraquat and / or diquat content in water, soil, vegetable, raw meat or biological samples, and is especially suitable for detection of the paraquat and / or diquat content in different substrates such as whole blood, plasma, urine, body fluids, tissues and the like, and the method has the advantages of simple operation, fast detection speed, high sensitivity and the like.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and relates to a method for rapidly detecting paraquat and / or diquat, in particular to a surface-enhanced Raman spectroscopic analysis method for the content of paraquat and / or diquat in biological samples of different substrates. Background technique [0002] Paraquat (PQ), also known as Gramoxone and Gramoxone, is a widely used quaternary ammonium Salt herbicides are extremely toxic to humans. Since the first use of paraquat in 1962, paraquat suicides and poisoning incidents have occurred frequently. Because there is no specific antidote, clinical treatment is very difficult, and the mortality rate of oral poisoning is over 90%. After paraquat is absorbed, it is distributed in the blood and systemic organs through the blood circulation, and is mostly excreted from the kidneys in its original form without being metabolized. Therefore, plasma and urine are often used as common samples for the...
