One of the priorities of environmental protection is the protection of water and water flows. With this problem, science has long been involved, but it is constantly trying to innovate and improve methods to raise water cleaning to a new level. The emergence of micro-pollutants in cleaned wastewaters and drinking water inspired the interest of scientists in finding solutions of their removal. An example of such a process is photocatalysis, which results in complete decomposition of micro-pollutants or the formation of non-hazardous degradation products. Photocatalysts such as titanium dioxide (TiO2) are used for this purpose. In this work a glass mesh was used as an immobilizer for TiO2. The immobilization of TiO2 on the glass mesh was carried out by the sol-gel method with two different drying methods; classic and microwave drying using different powers. Characterization of photocatalysts was obtained by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction analysis (XRD). The results of the SEM/EDS analysis indicate that particles with big dimensions have been attached to glass mesh which is dried with microwaves and it belong to TiO2. From the XRD results it can be concluded that the presence of the amorphous silane phase reduces the relative proportion of anatase and rutile and affects the reduction of the specific surface. The best results of photocatalytic degradation of salicylic acid were obtained using a mesh prepared using classical drying, which is also correlated with results.
