摘要
Abstract
Sodium hydrate was used as extracting agent,the ultrasonicwave method was used to extract 2,4-D in bean sprouts.The samples were purified by SPE and detected by UV detector.RT was used in qualitative analysis,and external standard method was used in quantitative calculation. The results showed that the standard curve was Y=4 024.187 3x-113.999 9,the correlation coefficient was 0.999 9,the linearity range was 0.05~10.00μg/mL,the detection limit of method was 0.02 mg/kg,the standard recovery was 90.3%~104.7%,and RSD was 0.52%~11.18%.关键词
