摘要
建立了蚊香烟雾中苯并(a)芘(BaP)的测定方法,并设计了蚊香烟雾的采样装置及采样方法.本方法采用咖啡因的甲酸溶液为萃取剂,具有准确、灵敏、快速的优点.最小检出限量为0.1ppb,变异系数为8.5％.应用本方法测定了不同类别蚊香中BaP的含量,获得满意结果.
A method has been developed for the determination of BaP in mosquito incense smoke.The apparatus for sample collection and analytical procedures are described.Caffeine-formic acid solution was used as the extracting agent.The method is found to be accurate,sensitive and rapid.The detection limit is 0.1 ppb and the coefficient of variation is 8.5%.The method has been used successfully for determining BaP in smokes produced from different kinds of mosquito incenses.A method has been developed for the determination of BaP in mosquito incense smoke.The apparatus for sample collection and analytical procedures are described.Caffeine-formic acid solution was used as the extracting agent.The method is found to be accurate,sensitive and rapid.The detection limit is 0.1 ppb and the coefficient of variation is 8.5%.The method has been used successfully for determining BaP in smokes produced from different kinds of mosquito incenses.
