Analytical method for detecting 1ambda-cyhalothrin residues in citrus fruits and soil
摘要
Abstract
[Objective]The goal of this experiment was to develop a rapid method for detecting lambda- cyhalothrin residues in citrus fruits and soil. [Method]The samples were extracted with methanol, cleaned up and concentrated on a florisil column, and analyzed by GC using μ-ECD. [Result]The linear relationship of lambda-cyhalothrin was found better in the concentration range from 0.005 to 1.000 μg/mL with the linear correlation coefficient of 0.9996. Minimum limit of detection in standard samples was recorded as 1.0×10-12 g in the present method, the lowest detectable concentration in citrus peel, pulp, and soil samples was 0.001 mg/kg. The average recovery varied from 91.24 to 104.61%, and the relative standard deviation ranged from 2.73 to 10.45%. [Conclusion]Owing to its good isolation effect, high recovery rate, rapidness, accuracy and high sensitivity, the GC method using μECD is immensely applicable to detect the lambda-cyhalothrin residues in citrus fruits and soil.关键词
