dc.description.abstract本文优化了萃取条件,建立了顶空-固相微萃取(HS-SPME)、气相色谱-质谱测定茶叶中4种多环芳烃的方法.茶叶中多环芳烃含量和对应的信号强度在0.3~150mg kg~(-1)范围内呈良好的线性关系,检出限为0.1~0.2mg kg~(-1),回收率在72.6%~102.4%之间;茶汤中含量和对应的信号强度在0.01~10mg kg~(-1)范围内呈良好的线性关系,检出限为0.005~0.01mg kg~(-1),回收率为76.4%~103.6%.
dc.description.abstractIn this study, GC-MS coupled head-space solid-phase microextraction(HS-SPME) was applied to detect 4 kinds of PAHs in tea and in tea infusion. After the optimization of the experimental consideration, the linear ranges for the PAH4 signal intensity and their concentrations are found to be 0.3–150 and 0.01–10 mg kg~(-1). The detection limit is 0.1–0.2 and 0.005–0.01 mg kg~(-1), with recovery of 72.6%–102.4% and 76.4%–103.6%, respectively.
