摘要
介绍了采用顶空气相色谱法对氯化石蜡-70中四氯化碳的含量进行测定,方法在0 01～0 10mg/kg范围,三个添加水平的回收率为83 01%～88 07%,变异系数(CV)为1 5%～4 6%,方法检出限为0 005mg/kg.该方法具有前处理简单、干扰因素小,对色谱系统污染小且快速、准确、分离完全等特点.
The carbon tetrachloride in chlorinated paraffins-70 was detected by GC.In range of 0.01～0.10?mg/kg,the method has the recoveries at three fortification levels of 83.01%～88.07%,the coefficients of variation (CV) is 1.5%～4.6%,limit of detection for the methodis is 0.005?mg/kg,and the method is simple,rapid and accurate.
