GAC-TiO2 Hybrid Materials for Efficient Filtration of Water

One of the important for life is water, which is required not only for drinking water but including for food preparation, processing, and sanitary. While, groundwater can be contaminated by chemicals, biological, and suspended solids. Water filtration is a general technique that removes particles and pollutants from water. So, we aim to develop a water purification system and study the efficiency of water filtration and self-cleaning of GAC-TiO2. TiO2-modified granular activated carbon hybrid materials (GAC-TiO2) synthesized by oven-assisted hydrothermal method. The structure and morphology of the composite were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The result showed that white powder of TiO2 coated on the surface of GAC. The XRD patterns of TiO2 powder showed the only anatase phase. SEM image of TiO2 powder coated on GAC observed that the GAC was covered by TiO2 particles. The shape of TiO2 powder coated on GAC was smooth and sphere particles. The size is about 3–4 µm. And then the water filtration efficiency of GAC-TiO2. It has been found that water after filtration has a higher quality than raw water and it can be reused and extended the life. In addition, it was found that photocatalytic activity is increased during UV irradiation thus enhancing the self-cleaning effect.
