【摘要】 用循环流动液相微萃取(CFME)和顶空法(HS)这两种预处理技术对水中挥发性卤代烃进行了分析和对比,并对影响CFME的因数进行了条件优化.结果表明优化后的CFME不仅在相同的线性浓度范围内有更好的线性关系,而且具有操作简单快速、经济廉价、准确可行的优点.更多还原

【Abstract】 By analyzing volatile halohydrocarbons in water sample,two pretreatment methods,continuous-flow liqulid-phase microextraction(CFME) and headspace(HS),are compared,and suitable conditions are optimised.The results show that the optimised CFME has higher linearity in the examined concentration range with correlation coefficients,and has the merits of rapid,inexpensive and reliable.更多还原
