【摘要】 药品和个人护理用品(PPCPs)被广泛应用于日常生活,其产生的废弃物也被大量地排放于环境中,常规的水处理并不能充分除去这些污染物,再生水中存在的PPCPs类污染物对生态系统存在很大的危害。采用超高效液相色谱-飞行时间质谱(UPLC-TOF-MS)对再生水中的PPCPs进行筛查,并通过超高效液相色谱串联质谱(UPLC-MS/MS)对筛查出的PPCPs进行确证与定量分析。为进一步提高污水处理流程和再生水再利用的风险评估提供了有效的数据方法。更多还原

【Abstract】 Pharmaceutical and personal care products(PPCPs) are widely used in daily life and large amounts of these chemicals would be discharged in its original or metabolic state into sewage. Due to the unique stability, the current WWTPs can not remove PPCPs completely, the accumulation of PPCPs in environment and the extent of influence to human health cannot be ignored.The samples were screened by usingultra-performance liquid chromatography-time of flight mass spectrometry(UPLC-TOF-MS) to find the presence PPCPs with high concentrations in reclaimed wastewater, and UPLC-tandem mass spectrometer(UPLC-MS/MS) was used to confirm these PPCPs. The resultprovidedthat the methodof empirical data is provided to further improve wastewater treatment processes and to assess the risk of RW reuse.更多还原
