Pharmaceutical contaminants are frequently encountered at trace concentrations in various environmental ecosystems. This study introduces a significant approach to water treatment and environmental remediation by combining liquid membrane and ozonation. Initially, diclofenac is transported across the supported liquid membrane using a neutral organic extractant Cyanex 923. The highest removal efficiency was achieved with a 40 % concentration of Cyanex923 dissolved in kerosene, resulting in a permeability of 10.2 cm/h. Additionally, diclofenac is extracted from different environmental matrices such as tap water and real effluent of wastewater, and the effect of ions species was studied. The post-ozonation in the stripping phase resulted in removal of pharmaceuticals and 72 % reduction of total organic carbon at pH = 10 and 45.3 g/Nm³ initial ozone concentration. The study also investigates the identification and tracking of the most prevalent by-product of diclofenac over time.

在各种环境生态系统中经常会遇到痕量浓度的药物污染物。这项研究介绍了一种结合液膜和臭氧化的水处理和环境修复的重要方法。最初，使用中性有机萃取剂 Cyanex 923 将双氯芬酸输送穿过支撑液膜。将 40% 浓度的 Cyanex923 溶解在煤油中时，可实现最高去除效率，渗透率为 10.2 cm/h。此外，从自来水和实际废水排出物等不同环境基质中提取双氯芬酸，并研究了离子种类的影响。汽提阶段的后臭氧化导致药物去除，并且在pH = 10和初始臭氧浓度45.3 g/Nm ^{3时总有机碳减少72%。}该研究还调查了随着时间的推移，双氯芬酸最常见的副产品的识别和跟踪。
