The trimetallic Fe/Al/Ti (1:1:1) nanocomposite (FAT), synthesized by an adaptable tuned chemical route, offers a new approach for water treatment, for example, the de-fluoridation and photodegradation soluble dye methylene blue (MB) at pH 7. FAT acted as a good fluoride scavenger in the presence of other co-ions and within a widespread pH range (pH 2-11). The photodegradation efficiencies were >90% for different concentrations of MB solutions. The characterization of FAT includes thermogravimetric analysis, X-ray diffraction, Fourier transform-infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, and ζ-potential analysis. Furthermore, the regeneration efficiencies of both the water treatments were checked, where the removal efficiency was not hampered significantly even after five batches. Spectroscopic techniques were adopted to perform the kinetic studies and to propose the probable mechanistic paths.
通过一种适应性可调的化学路线合成的三金属铁/铝/钛（1:1:1）纳米复合材料（FAT），为水处理提供了一种新方法，例如在pH值为7时对水进行除氟和光降解可溶性染料亚甲基蓝（MB）。在存在其他共存离子的情况下以及在较宽的pH范围（pH 2 - 11）内，FAT都表现为一种良好的氟清除剂。对于不同浓度的MB溶液，光降解效率均>90%。FAT的表征包括热重分析、X射线衍射、傅里叶变换红外光谱、扫描电子显微镜、透射电子显微镜和ζ电位分析。此外，还检查了两种水处理的再生效率，即使经过五批处理后，去除效率也没有受到显著影响。采用光谱技术进行动力学研究并提出可能的作用机理路径。
