Herein, TiO2 and ZnO photocatalysts were combined with the peroxydisulfate ion (PDS) to enhance the efficiency. ZnO was significantly more efficient in PDS conversion and SO4•− generation than TiO2. For ZnO, the PDS increased the transformation rate of the trimethoprim antibiotic from 1.58 × 10−7 M s−1 to 6.83 × 10−7 M s−1. However, in the case of TiO2, the moderated positive effect was manifested mainly in O2-free suspensions. The impact of dissolved O2 and trimethoprim on PDS transformation was also studied. The results reflected that the interaction of O2, PDS, and TRIM with the surface of the photocatalyst and their competition for photogenerated charges must be considered. The effect of radical scavengers confirmed that in addition to SO4•−, •OH plays an essential role even in O2-free suspensions, and the contribution of SO4•− to the transformation is much more significant for ZnO than for TiO2. The negative impact of biologically treated domestic wastewater as a matrix was manifested, most probably because of the radical scavenging capacity of Cl− and HCO3−. Nevertheless, in the case of ZnO, the positive effect of PDS successfully overcompensates that, due to the efficient SO4•− generation. Reusability tests were performed in Milli-Q water and biologically treated domestic wastewater, and only a slight decrease in the reactivity of ZnO photocatalysts was observed.}, year = {2023}, eissn = {1996-1944}, orcid-numbers = {Náfrádi, Máté/0000-0001-8055-0974; Alapi, Tünde/0000-0002-9869-9280; Farkas, Luca/0000-0003-0632-8712; Bencsik, Gábor/0000-0002-6905-0546; Janáky, Csaba/0000-0001-5965-5173} } @misc{MTMT:34104390, title = {Application of LEDs and low pressure mercury vapor lamps in UV/Chlorine process for the removal of trimethoprim antibiotic}, url = {https://m2.mtmt.hu/api/publication/34104390}, author = {Farkas, Luca and Teodóra, Dragic and Tímea, Molnár and Alapi, Tünde}, unique-id = {34104390}, year = {2023}, orcid-numbers = {Alapi, Tünde/0000-0002-9869-9280} } @article{MTMT:34034385, title = {A comparative study of femtosecond pulsed laser ablation of meloxicam in distilled water and in air}, url = {https://m2.mtmt.hu/api/publication/34034385}, author = {Nagy, Eszter and Heszlerné Kopniczky, Judit and Smausz Kolumbán, Tamás and Náfrádi, Máté and Alapi, Tünde and Bohus, János and Pajer, Viktor and Révész, Piroska and Ambrus, Rita and Hopp, Béla}, doi = {10.1038/s41598-023-36922-7}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {34034385}, issn = {2045-2322}, abstract = {The increasing prevalence of water insoluble or poorly soluble drugs calls for the development of new formulation methods. Common approaches include the reduction of particle size and degree of crystallinity. Pulsed laser ablation is a clean technique for producing sub-micrometre sized drug particles and has the potential to induce amorphization. We studied the effect of femtosecond pulsed laser ablation (ELI ALPS THz pump laser system: λ c = 781 nm, τ = 135 fs) on meloxicam in distilled water and in air. The ablated particles were characterized chemically, morphologically and in terms of crystallinity. We demonstrated that femtosecond laser ablation can induce partial amorphization of the particles in addition to a reduction in particle size. In the case of femtosecond pulsed laser ablation in air, the formation of pure meloxicam spheres showed that this technique can produce amorphous meloxicam without the use of excipients, which is a unique result.

In this work, BiOX (X = Cl, Br, and I) photocatalysts were investigated to activate PDS and enhance the transformation rate of various organic substances under UV (398 nm) and Vis (400–700 nm) radiation. For BiOCl and BiOBr, in addition to excitability, the light-induced oxygen vacancies are decisive in the activity. Although without organic substances, the BiOI efficiency highly exceeds that of BiOBr and BiOCl for PDS activation (for BiOI, 15–20%, while for BiOBr and BiOCl, only 3–4% of the PDS transformed); each BiOX catalyst showed enhanced activity for 1,4-hydroquinone (HQ) transformation due to the semiquinone radical-initiated PDS activation. For sulfamethoxypyridazine (SMP), the transformation is driven by direct charge transfer, and the effect of PDS was less manifested. BiOI proved efficient for transforming various organic substances even under Vis radiation. The efficiency was enhanced by PDS addition (HQ is wholly transformed within 20 min, and SMP conversion increased from 40% to 90%) without damaging the catalyst; its activity did change over three consecutive cycles. Results related to the well-adsorbed trimethoprim (TRIM) and application of biologically treated domestic wastewater as a matrix highlighted the limiting factors of the method and visible light active photocatalyst, BiOI.}, year = {2023}, eissn = {2073-4344}, orcid-numbers = {Alapi, Tünde/0000-0002-9869-9280; Náfrádi, Máté/0000-0001-8055-0974; Pap, Zsolt/0000-0002-8049-0809} }
