【摘要】 应用固相萃取和溶剂放空结合气相色谱/串联质谱法测定管道供水中增塑剂溶出物,对顺德地区管道供水中增塑剂溶出物水平进行监测。发现出厂水、管网水和二次供水主要存在DMP、DEP、DIBP、DBP、DEHP、DNOP 6种增塑剂溶出物。在一年中出厂水和管网水的增塑剂检出情况较为平稳,二次供水则于每年的2月和9月达到峰值。更多还原

【Abstract】 The optimum method for determination of plasticizer in pipeline water supply by gas chromatography/tandem mass spectrometry,combined with solid phase extraction and solvent vent mode sampling. It was applied to monitor the level of plasticizer in pipeline water supply in Shunde district. The results showed that there were six kinds of plasticizers in product water, tap water and secondary water, such as DMP, DEP, DIBP, DBP, DEHP and DNOP. In one year, the plasticizer detection of product water and tap water is relatively stable. The secondary water has fluctuation and reach its peak in February and September of year.更多还原
