Determination of Diazinon Residues in Milk by Gas Chromatography
摘要
Abstract
A gas chromatographic method was developed for the determination of diazinon residues in milk. Samples dissolved in acetone were extracted with n-hexane,cleaned with neutral alumina column, and determined by gas chromatography (flame photometric detector) after volume measurement with acetone. The recoveries of the determination were 73.4% -96. 2%. The values of intra and inter-assay RSD were in the range of 3.5% -9. 1% and 4.9% -7. 5%,respectively. The linear correlation coefficient was 0. 999 9. The detection limit was 2. 0 μg · Kg-1 and the limit of quantitation remained as 5.0 μg · Kg-1.关键词
