The ozonation of 90 chemically diverse organic micropollutants (OMPs) including four classes of illicit drugs and their metabolites was studied in pure buffered water, tap water and wastewater effluent at three specific ozone doses and three pH levels. The second order rate constants for the reaction of 40 OMPs with ozone were known and span across 8 orders of magnitude, from below 1 M−1 s−1 to above 107 M−1 s−1. 47 of the tested OMPs were removed to at least 90% at the highest specific ozone dose of 0.3 mM O3 per mM C at pH 7. However, most illicit drugs, including cocainics, amphetamines and ecstasy-group compounds, were ozone-resistant due to their lack of ozone-reactive functional groups. Exceptions included some opioids and the cocaine biomarker anhydroecgonine methylester which contain olefinic bonds and/or activated benzene rings. Different removal trends at different pH for OMPs were due to the combined effect of target compound speciation and ozone stability, leading to elimination of less than 70% for all OMPs at pH 11. In both tap water and wastewater effluent scavenging by matrix components led to lower ozone exposure compared to pure buffered water and consequently lower removal of OMPs. This multi-compound ozonation study utilised liquid chromatography-mass spectrometry to provide a large dataset on the removal of environmentally relevant OMPs, including those of interest for drinking water regulations. Besides including pharmaceutically active compounds that have not been studied with ozone before (e.g. gliclazide, anhydroecgonine methylester, quetiapine, 6-monoacetylmorphine), this study simultaneously shows ozonation data for a wide range of illicit drugs.

同时在不同水基质中臭氧化90种有机非法污染物（包括非法药物及其代谢物）
在三种特定臭氧剂量和三种pH值下，在纯缓冲水，自来水和废水中研究了90种化学上多样化的有机微污染物（OMP）的臭氧氧化，其中包括四种非法药物及其代谢物。已知用于40 OMP与臭氧反应的二级速率常数，其范围从1 M -1 s -1以下到10 7 M -1 s -1以上跨越8个数量级。在0.3 mM O 3的最高特定臭氧剂量下，将47种OMP去除至至少90％pH值为7时，每mM C的浓度。然而，大多数非法药物（包括可卡因，苯丙胺和摇头丸类化合物）由于缺乏与臭氧反应的官能团而具有抗臭氧性。例外情况包括一些阿片类药物和可卡因生物标志物脱水芽子碱甲酯，它们含有烯键和/或活化的苯环。OMP在不同pH值下的不同去除趋势归因于目标化合物形态和臭氧稳定性的综合作用，导致在pH 11时所有OMP的消除量均不到70％。在自来水和废水中，基质组分的清除导致与纯缓冲水相比，臭氧暴露量更低，因此对OMP的去除更低。这项多化合物臭氧化研究利用液相色谱-质谱法提供了有关去除环境相关OMP（包括饮用水法规中所关注的OMP）的大型数据集。除了包括以前没有用臭氧研究过的药物活性化合物（例如，格列齐特，脱水吗啡酮甲酯，喹硫平，6-单乙酰吗啡），该研究同时显示了各种非法药物的臭氧数据。
