| 摘 要： | 以O-2,3,4,5,6-pentafluorobenzylhydroxylamine（PFBHA）和bis（trimethylsilyl）trif-luoroacetamide（BSTFA）为衍生化试剂,建立了同步分析城市污水厂二级出水臭氧深度处理出水中的醛（甲醛、乙醛、丙醛、乙二醛）和羧酸（丙酮酸）的双衍生气相色谱-质谱（GC-MS）方法。在电子轰击（EI）源下用选择离子模式进行分析,结果表明：甲醛、乙醛、丙醛在5μg/L～2mg/L,乙二醛和丙酮酸在5μg/L～1mg/L浓度范围内线性较好;各种物质的检测回收率均在74%以上,平均相对标准偏差〈14%。对实际水样的测定表明,污水厂二级出水中含有少量的醛类和丙酮酸,臭氧处理会导致这些物质明显增加。 |

| Abstract: | A method of GC/MS with double derivation for simultaneous detection of aldehydes and carboxylic acids in the ozonated secondary effluent from a WWTP was established by using O-2,3,4,5,6-pentafluorobenzylhydroxylamine (PFBHA) and bis(trimethylsilyl)trifluoroacetamide (BSTFA) as derivatives. An analysis was performed with electron bombardment source in selected ion monitoring mode. The results show that formaldehyde,acetaldehyde and propionaldehyde have a good linear relationship within the concentration rang... |
