气相色谱-质谱法测定食品用纸制品中五氯酚含量
目的 建立气相色谱-质谱法测定食品用纸制品中五氯酚含量的分析方法,了解食品用纸制品中五氯酚的残留状况.方法 纸制品试样加入2,4,6-三溴酚内标后,经液-液萃取,SLC柱净化,乙酸酐-吡啶溶液衍生后,采用气相色谱-质谱法测定,内标法定量.结果 在50～1000 ng范围内,相关系数均>0.9995.方法 的检出限为0.008 mg/kg,定量限为0.025 mg/kg.加标回收率为89.3％～109.8％,相对标准偏差(relative standard deviations,RSDs)分别为3.2％、8.6％和4.4％.106份市售纸制品中,8份样品检出五氯酚,阳性率为7.5％,含量范...
