| 摘 要： | 建立了用气相色谱法同时测定苯酚生产废水中异丙苯、α-甲基苯乙烯、α-甲基苯甲醇、2-苯基-2-丙醇、苯酚、苯乙酮、2-苯基丙醛等7种芳香族有毒有机污染物的定量分析方法。采用二氯甲烷对水样进行萃取后进行分析测定,气相色谱条件:DB-WAX型色谱柱,FID检测器,程序升温,进样量1μL。方法的检出限、精密度、回收率实验表明,该方法对苯酚生产废水中各污染物组分具有较好的分离效果,对7种物质的检测限均低于0.05 mg/L,5次测定的相对标准偏差小于5%,实际水样的加标回收率大于97%。

| Abstract: | A new method is established for the quantitative analysis of the aromatic toxic organic pollutants in the wastewater discharged by phenol-acetone unit,such as cumene,2-phenyl-1-phenylethanol,2-phenyl-2-propanol,phenol,acetophenone,2-phenylpropionaldehyde.Liquid-liquid extraction used to pretreatment the wastewater using dichloromethane as the extraction.Extraction phase was measured by gas chromatography which using DB-WAX-type column and FID detector by programmed temperature.The sample size was 1 μL.The results showed that all the compounds were full separated under the analysis conditions.The sensitive,detection limits and recovery met the analysis requirements. |
