固相萃取-高效液相色谱/质谱串联法分析奶牛饮用水中莠去津及其6种代谢物的残留OA北大核心CSCDCSTPCD
Determination of Trace Atrazine and its Six Metabolites in Water by Solid Phase Extraction and Liquid Chromatography/Mass Spectrometry
建立了高效液相色谱质谱联用检测奶牛饮用水中莠去津及其6种代谢物残留的同步分析方法.利用MCX固相萃取柱富集净化,采用液相色谱-质谱串联进行测定,外标法定量.结果表明莠去津及其代谢物在0.4 ～ 100 μg/L范围内线性良好,标准曲线相关系数r2均大于0.99.在0.03 ～3 μg/L浓度范围内,平均加标回收率除脱异丙基羟基莠去津的较低(64.17％)外,其他目标物的回收率在71.31％～116.67％之间,相对标准偏差为0.97％～12.03…查看全部>>
A sensitive LC-MS/MS method for simultaneously analyzing atrazine and its 6 metabolites in cattle drinking water was established. The samples were enriched and purified by MCX solid-phase column, determined by LC-MS/ MS, and quantified by outer standard. The results showed that the linear range spanned from 0.4 to 100μg/L with correlation index r2 greated than 0. 99. At the concentration range of 0. 03 ～3 μg/L, except the recovery of desisopropyl-2-hydroxy w…查看全部>>
