Water pollution stemming from non-metal contaminants, notably fluorine, poses a grave health risk. The prevalent organic fluoride called pentafluoropropionic acid (PFPA), necessitates efficient remediation. Employing photocatalysis, this study strives to synthesize titanium dioxide (TiO) via microwave assisted sol-gel technique, integrating a natural-resource-based zeolite carrier to synthesize photocatalyst/zeolite nanocomposite for the removal of fluorinated compounds from water by degradation of PFPA. Minitab-17 facilitates data analysis, with the reaction surface (RS) method optimizing parameters: 0.5 g dosage, UV irradiation, and alkaline conditions. The RS model predicts a 60.2 % removal efficiency, closely aligning with the observed 58.7 % removal. Energy efficiency is pursued through microwave hydrothermal synthesis, while secondary aluminium slag and waste glass contribute to zeolite synthesis, promoting waste reduction and recycling in harmony with circular economy principles.

通过 TiO2 合成沸石复合材料增强五氟丙酸 (PFP​​A) 的光降解：有效脱氟的可持续方法

非金属污染物（尤其是氟）造成的水污染构成严重的健康风险。常见的有机氟化物称为五氟丙酸 (PFP​​A)，需要有效的修复。本研究采用光催化，致力于通过微波辅助溶胶凝胶技术合成二氧化钛（TiO），整合基于自然资源的沸石载体，合成光催化剂/沸石纳米复合材料，通过降解 PFPA 去除水中的氟化物。 Minitab-17 通过反应表面 (RS) 方法优化参数：0.5 g 剂量、UV 照射和碱性条件，促进数据分析。 RS 模型预测去除效率为 60.2%，与观察到的 58.7% 去除率密切一致。通过微波水热合成追求能源效率，而再生铝渣和废玻璃有助于沸石合成，促进废物减量和回收，与循环经济原则相协调。
