Farmacevtiki sodijo med organska onesnaževala, ki jih najpogosteje zaznamo v vodnem okolju (v odpadni vodi, podtalnici, tleh, površinskih vodah in živih organizmih). Njihova prisotnost močno vpliva na okolje in zdravje ljudi, živali. S tem razlogom se je začel razvoj raziskav in postopkov za razgrad ...

Fotokataliza je ena izmed ključnih metod na področju trajnostne kemije, saj se njena uporabnost izkazuje na različnih področjih, vključno s čiščenjem onesnaženih voda. Zaradi povečanega obsega farmacevtske industrije in drugih antropogenih posegov v naravo se v vodi kopičijo organske snovi, ki jih o ...

Hydrothermal reactions represent a simple and efficient method for the preparation of nanostructured TiO$_2$ particles that could be of interest as photocatalysts or catalytic supports. Although the particle size is in the range of 2–5 µm, the nanostructures composing the particles ensure a large sp ...

In the present study, a Bi$_2$WO$_6$/ZnWO$_4$ photocatalyst was successfully constructed by a modified hydrothermal synthesis method with different molar concentrations of Bi$_2$WO$_6$ with respect to ZnWO$_4$. The variation in molar concentrations of Bi$_2$WO$_6$ changed the photocatalytic properti ...

In recent years, the increasing demand for clean and potable water has created a need for efficient, cost-effective wastewater treatment. One of the most promising methods is heterogeneous photocatalysis due to its ability to mineralize organic molecules. This paper describes the development of a fl ...

The application of TiO 2 photocatalysis in various environmental fields has been extensively studied in the last decades due to its ability to induce the degradation of adsorbed organic pollutants. In the present work, TiO 2 powders doped and co-doped with sulfur and nitrogen and modified with plati ...

The effect of different water matrices on the photocatalytic degradation of dissolved pharmaceuticals was
explored. The focus was on the degradation efficiencies in wastewater effluent from a bioreactor and water
effluent from a central wastewater treatment plant and comparing the results with deg ...

V zadnjih desetletjih postaja dostop do čiste vode vse večja težava, ki jo lahko pripišemo eksponentni rasti prebivalstva in industrializaciji, zaradi česar se je pojavila potreba po ponovni uporabi očiščenih vod. V ta namen je bilo razvitih veliko metod za čiščenje odpadnih voda, ki pa so lahko pri ...

When wood is thermally modified, several chemical reactions take place that change the chemical and physical properties of the wood. These changes correlate with the degree of modification, which is mostly a function of the temperature and duration of modification, and consequently with the mass los ...

Sulfur-doped TiO$_2$ (S-TiO$_2$) composites with reduced graphene oxide (rGO), wt. % of rGO equal to 0.5%, 2.75%, and 5.0%, were prepared by a one-pot solvothermal procedure. The aim was to improve photocatalytic performance in comparison to TiO$_2$ under simulated solar irradiation for the treatmen ...
