| 中文摘要: |
| 目的 建立固相萃取-气质联用法检测(SPE-GC/MS/SIM)分析方法,检测鱼塘水中微量敌敌畏、氯氰菊酯、硫丹和五氯酚含量。方法 取1000ml鱼塘水进行固相萃取,洗脱后浓缩进行GC/MS/SIM定性定量测定。结果 固相萃取对4种毒物浓缩提取后,各项定量参数符合分析要求。鱼塘水中敌敌畏农药的最低检测限为0.1ng/ml,氯氰菊酯的最低检出限为5ng/ml,硫丹和五氯酚的最低检出限为1ng/mm。结论 SPE-GC/MS法简单、灵活、经济、快速、无溶剂,适用于鱼塘水中微量毒物分析。 |

| Objective To establish an analysis method of detection of trace dichlorvos (DDVP),cypermethrin,endosulfan and pentachlorophenol (PCP) in fishpond water by gas chromatography-mass spectrometry in selected ion monitoring (GC/MS/SIM) with solid phase extraction (SPE).Methods 1000ml fishpond water was treated with SPE.After being eluted and concentrated,the water sample was treated with qualitative and quantitative analysis by GC/MS/SIM.Results After concentration and extraction of four toxicants with SPE,the quantitative parameters for the fishpond sample conformed to the requirements of analysis.The detection limit for DDVP in fishpond water was 0.1 ng/ml,5 ng/ml for cypermethrin,1 ng/ml for endosulfan and PCP.Conclusion The SPE-GC/MS was simple,flexible,economic,fast,solvent-free,which was suitable for traces analysis of poison in fishpond water. |
