Aqueous pharmaceuticals present an emerging environmental problem for their potent character. Advanced oxidation processes (AOPs) present efficacious abatement strategy, being, however, unaffordable in mass application. Energy efficient gas-phase pulsed corona discharge was experimentally studied for oxidation of aqueous ibuprofen, diclofenac, metformin and tramadol showing the energy yields of 53, 21, 15 and 89 g kW-1 h-1, respectively, at 10 mg L-1 initial concentrations, surpassing other AOPs. Impacts of alkaline pH and starting concentrations on oxidation energy efficiency are beneficial to various extents to all considered pharmaceuticals. The removal efficiency was found to correlate with molecular structure and hydrophobicity of medications.

水性药物由于其强大的特性而提出了一个新出现的环境问题。先进的氧化工艺（AOP）提出了有效的减排策略，但是在大规模应用中却难以承受。实验研究了高能效气相脉冲电晕放电对布洛芬，双氯芬酸，二甲双胍和曲马多水溶液的氧化作用，显示在10 mg L-1时的能量产量分别为53、21、15和89 g kW-1 h-1。初始浓度，超过其他AOP。碱性pH和起始浓度对氧化能效的影响在各种程度上对所有考虑的药物都是有益的。发现去除效率与药物的分子结构和疏水性相关。
