| titleOfInvention | Preparation method of test paper for detecting organophosphorus pesticide |
| abstract | The invention relates to a test paper for rapidly detecting organophosphorus pesticide, which comprises the following components in part by weight: by utilizing a multilayer composite means, the liquid to be detected containing the organophosphorus passes through the upper, middle and lower layers of filter paper which are fixed with different reagents and have different functions respectively, so that the aim of rapidly detecting the organophosphorus pesticide by utilizing a color development method is fulfilled. Firstly, each layer of filter paper is printed with a water passing area and a water blocking area by a wax spraying printer, then a hydrophobic adsorption material is fixed in the water passing area of the upper layer of filter paper, a buffer salt is fixed in the water passing area of the middle layer of filter paper, an oxidation-reduction color developing agent is fixed in the water passing area of the lower layer of filter paper, and a film is tightly attached to the bottom of the lower layer of filter paper. Organic phosphorus is adsorbed by hydrophobicity in the process of permeating the upper layer, is continuously concentrated and enriched in the upper layer filter paper, then enters the lower layer after the pH value is adjusted by alkaline hydrolysis and buffer salt fixed in the middle layer, is oxidized by the oxidant of the lower layer, generates color change after the oxidant is reduced, and judges whether organic phosphorus pesticide exists or not through the color change. |
