AB  - The presence of different organic pollutants in water leads to the need to apply different technologies
and processes for their removal. Organic pollutants can cause several negative impacts on
surrounding environment, inducing detrimental effects on living beings. Fungicides represent one of
the biggest groups of crop protective agent with increased yearly consumption, frequently ending up
in non-target organisms. Therefore, aim of this study was to determine the possibility of using two
synthesized nanocatalysts Ag-P25 and Ce-P25 in several consecutive removal cycles of present
pollutant in water. Catalysts were applied in process of photocatalytic degradation of fungicide
thiophanate-methyl at atmospheric conditions. After each irradiation cycle, catalysts were collected,
rinsed, dried, and applied in upcoming operational run. Fabricated catalysts were also likened to
starter TiO2 material. After fifth cycle, FTIR and XRD characterization techniques were used for
proving stability of materials. Obtained results show that Ce-P25 possesses (98%) better stability than
Ag-P25 (96%), but base TiO2 (99%) has the best stability and efficiency after second cycle. Gathered
findings can open a new way of employing photocatalysis as a process for treatment of polluted waters
from various industries.

AB  - This study focuses on establishing an efficient two-step technology, which includes: (1) consecutive adsorptiondesorption,
using cellulose-based membranes, bCells, and (2) photocatalytic degradation of the fungicide
thiophanate-methyl (TPM), using synthesized Ag-P25 and Ce-P25 catalysts. The catalysts, obtained by
controlled deposition of Ag2O/Ag and CeO2 onto P25 TiO2 carrier (Degussa), were characterized using ATRFTIR,
XRPD, BET, FESEM, HRTEM, HAADF-EDS and UV–DRS techniques. In order to establish a feasible purification
technology, preconcentration of TPM was performed by adsorption, achieving 75.5 and 92.9 mg/g of
TPM removal using bCell-EpL and bCell–EpL–TA membranes, respectively, followed by efficient desorption (>
95%) that provided acceptable TPM concentration for photodegradation experiments. Under optimal conditions
(0.07 g/L of both catalysts), complete degradation of TPM (5 mg/L) occurred within 2 h, compared to 4 h for the
base TiO2 P25. Measurements of quantum yield and the results of HPLC-MS analysis, alongside DFT calculation,
assisted in understanding the TPM degradation pathways. New degradation products were detected and proposed
from HPLC–MS analysis. Embryotoxic assays, performed on zebrafish (Danio rerio), applied to estimate the
toxicity evolution of time-dependent generated TPM degradation products, showed low embryotoxic potential.
Chemical oxygen demand (26 mg O2/L) confirmed low ecotoxicological pressure of effluent water.
