Abstract
Water is the key element for the development and maintenance of life on the planet. However, in recent decades, water has consistently been burdened with organic and inorganic pollutants. Therefore, in addition to the proper management of existing stocks, its treatment and reuse become necessary actions to protect public health and the environment.
Conventional water and wastewater treatment methods have been found to be ineffective in removing various harmful, toxic or non-biodegradable organic substances. This makes it imperative to apply advanced treatment methods capable of removing the above pollutants.
The purpose of this thesis is to study the photocatalytic degradation of acyclovir in aqueous solutions under the influence of UV-Α radiation, and the use of titanium dioxide (TiO2) as a photocatalytic medium.
The experiments conducted were divided into three groups. In the first group, an attempt was made to determine the effect of the initial concetration of acyclovir on its degradation. The second group investigated the effect of radiation intensity. Finally, the effect of the addition of sodium persulfate on the degradation of acyclovir was studied.
