| 中文摘要 | 建立了以丙酮和石油醚超生提取,用硫酸、高纯铜粉和硅胶柱净化的可同时检测长江三角洲地区城市污泥中有机氯污染物的气相色谱法。与传统方法相比,在保证足够准确度、精确度和灵敏度的前提下,该方法具有前处理简单、测定成本低、样品用量少的特点,且可同时测定城市污泥中有机氯农药(OCPs)和多氯联苯类(PCBs)化合物。应用该方法对我国长江三角洲地区城市污泥中PCBs和OCPs进行测试,结果表明,方法最低检出限为0.09~ 0.33 μg/kg,达到了微量分析要求。加标回收试验中,PCBs回收率为59.50%~101.51%,OCPs回收率为57.21%~ 89.62%,相对标准偏差为1.89%~14.67%。 |
| 英文摘要 | A method was developed for the simultaneous analysis of PCBs and OCPs in sludges from the Yangtze River Delta Region of China by gas chromatography with electron capture detection (GC-ECD). The method involved was activated by ultrasonic extraction using acetone and petroleum ether, clean-up with sulfuric acid, copper power treatment and silica gel column chromatography. The test results with this method showed that the recovery (57.21% ~101.51%), relative standard deviation (1.89%~14.67%) and detection limits (0.09~0.33 mug/kg) could be satisfactorily obtained. This method was also cost-effective and did not require large amount of sludge sample. It could determine PCBs and OCPs in the same extract with enough accuracy, sensitivity and permissible RSD. PCBs and OCPs in the municipal sludges derived from the Yangtze River Delta Region of China were detected with this method. |
