Description
Technical Field
The invention belongs to the field of pendimethalin detection, and particularly relates to a test strip for detecting pendimethalin.
Background
Pendimethalin belongs to dinitroaniline herbicides, is a pure orange crystalline solid, has a relative density of 1.19 (25 ℃), has a solubility in water of 0.33mg/L (pH 7, 20 ℃), is easily soluble in benzene, toluene, chloroform, is slightly soluble in petroleum ether and the like. The volatility is small, the photolysis is not easy, and the product is stable to acid and alkali. As a systemic conduction type selective pre-emergence herbicide, the herbicide is widely applied to prevention and removal of annual weeds in cotton, corn, rice, potatoes, soybeans, peanuts, tobacco and vegetable fields. Pendimethalin can trigger mice to suffer from thyroid follicular adenoma, is highly toxic to fish and invertebrate organisms in water, is also a potential carcinogen for humans, and has been listed by the U.S. Environmental Protection Agency (EPA) as a persistent bioaccumulative toxic substance (PBT).
The nonstandard use of pendimethalin can cause pesticide residue in agricultural products to exceed standard, and the personal safety of consumers is affected. In addition, with the increasing emphasis of pesticide residue problems in various countries in the world, strict limit standards are formulated for pendimethalin residues in various agricultural and sideline products. The residue of pendimethalin exceeds the standard, which is liable to influence the national trade of agricultural products and foods in China. Conventional pendimethalin is typically measured by chromatography, such as gas chromatography. Although the chromatographic method is accurate in detection, the pretreatment is complex, the time is long, the detection cost is high, and the requirements of on-site rapid detection and emergency treatment of agricultural and sideline products cannot be met.
In view of the shortcomings of the prior art, a test strip for detecting pendimethalin is needed, the detection is sensitive, and the detection efficiency can be improved.
