| titleOfInvention | Fast analysis method for detecting lufenuron residues in apples and soil |
| abstract | The invention provides a fast analysis method for detecting lufenuron residues in apples and soil and belongs to the technical field of analysis and detection. The method comprises the following steps: extracting a sample by using acetonitrile to obtain an extracting solution, salting out the extracting solution without purification to obtain supernate, concentrating the supernate, re-dissolving to obtain a solution I, enabling the solution I to passing through a film to obtain a solution II, and feeding the solution II into a machine for testing directly, wherein the sample is separated by adopting a Hypersil C18 (100mm*2.1mm,1.9 microns) chromatographic column, methyl alcohol-water (60 to 40) is used as a flowing phase, the detection is performed by an ultraviolet detection device after isocratic elution, and the detection wave length is 255nm. Results show that a linear relation of the lufenuron is good within a concentration range of 0.025-2.5mg/L, related factors are not less than 0.9997, the average recovery rate is 83.6-105.2% within a marking concentration range being 0.05-2.0mg/kg, the relative standard deviation is 0.7-6.1%, and the detection limit in the method is 0.01mg/kg. |
