摘  要:
采用固相微萃取技术测定浓缩苹果汁中有机磷农药残留量,对固相微萃取条件进行了选择。结果表明,本法的回收率在69.2%~103.2%之间,相对标准偏差在0.98%~4.8%之间,8种有机磷最低检出浓度为0.4~4.1ng/L。

摘  要:
A method for the determination of eight organophosphorus pesticide residues (OPs) in apple juice concentrate by fiber solid phase microextraction (SPME) coupled with gas chromatography was developed. The extraction conditions were optimized. The average recoveries and relative standard deviations of the pesticides were 69.2% to 103.2% and 0.98% to 4.8% respectively. The detection limits of OPs were in the range of 0.4 ng/L to 4.1 ng/L. In conclusion,this method is rapid,accurate and easy for determining pesticides residues in apple juice concentrate.
