摘  要:
采用高效液相色谱对饮用水、青菜两种典型食品中高效氯氟氰菊酯的定量检测。研究表明,采用丙酮-正己烷提取饮用水中高效氯氟氰菊酯、利用丙酮-石油醚提取青菜中高效氯氟氰菊酯效果较好,液相色谱检测时以乙腈-水(80:20,V/V)作为流动相,230nm条件下检测峰型较好,在农药浓度为0.1×10-6~10×10-6时,两组萃取剂的回收率分别为97.93%~103.02%和91.4%~113.9%,相对标准偏差均小于4%。该方法操作简单、快速,能够在食品安全检测中发挥一定的积极作用。

摘  要:
A HPLC method was developed for the analysis of lambda-cyhalothrin residue in drinking water(from polluted rivers) and Brassica chinensis leaves.The analysis was performed on a SB-C18 column using acetonitrile-water(80:20,V/V) as a mobile phase at the flow rate of 1.25 ml/min and detection wavelength was set as 230 nm.Compared to other solvents,acetone-n-hexane(1:1,V/V) mixture exhibited the highest extraction efficiency to lambda-cyhalothrin(the highest recovery) from drinking water.Acetone-petroleum ether(1:1,V/V) mixture led to the highest recovery for lambda-cyhalothrin from ground Brassica chinensis leaves,and vortex-mixing extraction was adopted due to the highest the highest recovery for lambda-cyhalothrin as well as its time-saving contribution.The recoveries for lambda-cyhalothrin in drinking water and ground Brassica chinensis leaves spiked at three levels were in the rages of 97.93%-103.02% and 91.4%-113.9%,respectively,and the RSDs were less than 4%.This method is proved to be easily performed and time saving(within 30 min) and can be applied in the food safety detection.
