Abstract

The present invention relates to a rapid assaying card to detect organic phosphor and carbamate pesticide residues in various agricultural products. Organic phosphor and carbamate pesticide pesticides are commonly used in China as main residual pesticide in vegetables, fruit and other agricultural products. In order to meet demand for rapid circulation of agricultural products, the rapid assaying card as a product to rapidly, easily and economically detect organic phosphor and carbamate pesticide residues emerges. However, rapid assaying cards current sold in the market suffer from serious false positive while detecting white turnip, garlic and so on, thus restricting applicable scope of the rapid assaying card. The rapid assaying card provided by the present invention to detect organic phosphor and carbamate pesticide residue in various agricultural products comprises 1% dilute sulphuric acid pre-processing reagent, 0.2% oxydol detection result confirmation reagent, and rapid assaying card composed of ferment tablets and substrates and 0.1 mol / L pH 7.5 phosphate buffers.

Description

technical field [0001] The invention relates to a rapid detection card capable of detecting organic phosphorus and carbamate pesticide residues in various agricultural products. Background technique [0002] Organophosphorus pesticides and carbamate pesticides are currently the most commonly used pesticides in my country, accounting for about 75% of the total amount of pesticides. These two types of pesticide residues are also the main pesticide residues in agricultural products such as vegetables and fruits in my country at present, which are very harmful to humans and animals. In order to strictly control its harm to humans and animals, extremely strict regulations have been made on the maximum allowable residues in various vegetables and fruits, and they are used as mandatory testing indicators. The current detection method is mainly gas chromatography. This method has disadvantages such as complicated sample pretreatment process, long detection time, high detection cost...
