文章系统研究了地表水中四乙基铅的自动顶空-气相色谱分析方法,优化了进样条件,外标法定量,检出限及测定下限分别为0.05μg/L和0.2μg/L,试剂空白水和实际样品平行测定相对标准偏差均小于5%,地表水和废水样品加标回收率在86.8%~104%之间。此外还对样品的保存条件和期限进行了探索性研究。 The article systematically studied the method of automatic headspace-gas chromatographic analysis of tetraethyl lead in surface water, optimized the conditions of injection, the external standard method, the detection limits and the lower limits of determination were 0.05μg / L and 0.2μg / L respectively. The reagents The relative standard deviations (RSDs) of blank water and actual samples were all less than 5%. The spiked recoveries of surface water samples and wastewater samples were 86.8% -104%. In addition, the preservation conditions and deadlines of the samples were explored.
