| 摘 要： | 建立了气相色谱负离子化学电离源质谱法测定污水样品中溴代阻燃剂(BFRs)的分析方法.水样采用经典的液液萃取法同时提取水相和颗粒相中的BFRs,经过硅胶净化,采用优化的气相色谱质谱分析条件进行定量分析,实验方法经过严格的质量保证和控制步骤,回收率,精密度,仪器分析条件均满足定量分析的要求.分析污水结果表明,进水BFRs浓度在119.2 ng·L-1,三级出水7.5 ng·L-1,其中BDE-209和HBCD分别占进水溴代阻燃剂总量的53.9%和29.9%.总体浓度低于国内已经报道的水平.

| Abstract: | A method for the detection of Brominated Flame Retardants(BFRs) in wastewater by gas chromatography-negative ion chemical ionization mass spectrometry(GC-NCI/MS) has been developed.The water sample was extracted by classical liquid-liquid extraction method to collect the BFRs from both particle phase and water phase,cleaned up using silica gel then analyzed by GC-NCI/MS under the optimized conditions.All analytical procedures were subjected to strict quality assurance and control procedures.Recovery,precisi... |
