AB  - Pollution of water presents one of the biggest problems of modern society. Pesticide
production, usage and release, as well as their persistence in the environment, have
detrimental effects on the aquatic and non-target species. Therefore, it is necessary to apply
treatment techniques in order to prevent these negative consequences. The processes used
so far do not have the necessary efficiency to optimally solve this problem. Hence, plenty
of advanced oxidation processes (AOPs) has been developed, among which photocatalysis
has stood out. Thus, photocatalytic degradation of fungicide thiophanate-methyl by using
recently synthesized catalyst Ag2O/TiO2 was considered. The effect of the various
parameters, such as catalyst amount, fungicide concentration, and also the distance of the
lamp from the photocatalytic reactor was studied. The obtained photocatalyst was examined
using Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy
(SEM), as well as Diffuse reflectance spectroscopy (DRS). Photocatalytic assays
employing Ag2O/TiO2 catalyst with the concentration of 0.065 g/l yielded the best results.
The degradation rate constant was measured as 0,040 min-1 by observing values of
absorbances from the UV spectrophotometer Shimadzu 1800. Under the optimal
conditions, the complete disappearance of 10 mg/l of fungicide occurred within 2 h by
using Ag2O/TiO2. However, the limitation of the applied process is reflected in the volume
of wastewater that can be treated, while making it economically viable. Obtained results
show that synthesized catalysts pose a great ability to effectively decompose thiophanatemethyl
under UV light.
