In the present study, polymer supported nanocomposites, consisting of bio-based poly(ethylene furanoate) polyester and TiO2 nanoparticles, were prepared and evaluated as effective photocatalysts for anti-inflammatory/analgesic drug removal. Nanocomposites were prepared by the solvent evaporation method containing 5, 10, 15, and 20 wt% TiO2 and characterized using Fourier Transform Infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Thin films of them have been prepared by the melt press and optimization of the photocatalytic procedure was conducted for the most efficient synthesized photocatalyst. Finally, mineralization was evaluated by means of Total organic carbon (TOC) reduction and ion release, while the transformation products (TPs) generated during the photocatalytic procedure were identified by high-resolution mass spectrometry.
在本研究中,制备并评估了由生物基聚乙烯呋喃酮聚酯和二氧化钛纳米颗粒组成的聚合物支撑纳米复合材料,作为抗炎/镇痛药物去除的有效光催化剂。纳米复合材料通过溶剂蒸发法制备,含有5、10、15和20 wt%的二氧化钛,并利用傅里叶变换红外光谱(FTIR)、差示扫描量热法(DSC)、宽角X射线衍射(WAXD)、热重分析(TGA)和扫描电子显微镜(SEM)进行表征。通过熔融压制制备了它们的薄膜,并对最有效的合成光催化剂进行了光催化程序的优化。最后,通过总有机碳(TOC)减少和离子释放评估了矿化,同时通过高分辨质谱鉴定了光催化程序中生成的转化产物(TPs)。
