In recent years, the continuous and uncontrollable presence of drug contaminants and their destructive effects on the environment has been raised as an environmental problem. A large proportion of drug contaminants are related to sedatives. Paracetamol is one of the most widely used sedatives in the world. In this study, the photocatalytic degradation of paracetamol under visible light in the presence of poly(glycidylmethacrylate)@polyaniline/CuO nanocomposite as a photocatalyst was investigated. This prepared nanocomposite was characterized by different techniques such as Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and transmission electron microscopy (TEM). The effect of various parameters such as the amount of photocatalyst, irradiation time, temperature, and pH of the solution was studied on drug degradation. The degradation of paracetamol (PA) was assessed by adding a number of radical scavengers to the solution. More than 99% of paracetamol (10 mg L−1) was degraded under operating conditions in 90 min.

CuO纳米棒在聚（甲基丙烯酸缩水甘油酯）@聚苯胺核壳微球上的组装：对乙酰氨基酚的光催化降解
近年来，药物污染物的持续和无法控制的存在及其对环境的破坏性影响已被列为环境问题。很大一部分药物污染物与镇静剂有关。扑热息痛是世界上使用最广泛的镇静剂之一。在这项研究中，研究了在聚（甲基丙烯酸缩水甘油酯）@聚苯胺/CuO纳米复合材料作为光催化剂存在下，可见光下对乙酰氨基酚的光催化降解。这种制备的纳米复合材料通过不同的技术进行表征，例如傅里叶变换红外 (FT-IR)、扫描电子显微镜 (SEM)、能量色散 X 射线光谱 (EDX)、热重分析 (TGA)、X 射线衍射 (XRD)和透射电子显微镜 (TEM)。研究了光催化剂用量、照射时间、温度、溶液pH等各种参数对药物降解的影响。对乙酰氨基酚 (PA) 的降解通过向溶液中添加多种自由基清除剂来评估。超过 99% 的扑热息痛 (10 mg L-1 ) 在操作条件下在 90 分钟内降解。
