The photocatalytic deactivation of volatile organic compounds and mold fungi using TiO2 modified with mono‐ and bimetallic (Pt, Cu, Ag) particles is reported in this study. The mono‐ and bimetal‐modified (Pt, Cu, Ag) titanium(IV) oxide photocatalysts were prepared by chemical reduction method and characterized using XRD, XPS, DR/UV‐Vis, BET, and TEM analysis. The effect of incident light, type and content of mono‐ and bimetallic nanoparticles deposited on titanium(IV) oxide was studied. Photocatalytic activity of as‐prepared nanocomposites was examined in the gas phase using LEDs array. High photocatalytic activity of Ag/Pt‐TiO2 and Cu/Pt‐TiO2 in the reaction of toluene degradation resulted from improved efficiency of interfacial charge transfer process, which was consistent with the fluorescence quenching effect revealed by photoluminescence (PL) emission spectra. The photocatalytic deactivation of Penicillium chrysogenum, a pathogenic fungi present in the indoor environment, especially in a damp or water‐damaged building using mono‐ and bimetal‐modified (Pt, Cu, Ag) titanium(IV) oxide was evaluated for the first time. TiO2 modified with mono‐ and bimetallic NPs of Ag/Pt, Cu, and Ag deposited on TiO2 exhibited improved fungicidal activity under LEDs illumination than pure TiO2.

“…Modication of a support material with ILs can increase the extraction efficiency by introducing different interactions between the sorbent and target analyte, including ion-exchange, hydrophobic, electrostatic, hydrogen bonding, and p-p interactions. 33,34 Some IL-modied ZIFs have been reported in recent years, and these ZIFs are attractive in many research elds, especially for sample pretreatment. 35 To the best of our knowledge, no ZIF-8/IL-based composite adsorbent has been reported for the analysis of pyrethroids in a tea infusion.…”

“…VAHs, which are subgroup of VOCs, have also been a significant class of organic pollutants in the worldwide recently because of several negative effects. Thus, they should be analyzed the type and quantity of them especially in environmental waters to reduce their toxic impacts and to monitor for human life [3][4][5][6][7]. VAHs are organic chemicals and composed of carbon chains and their derivatives.…”

A wide range of chemicals comes to exist at the end of the industrial activities. They could have highly toxic and carcinogenic effects on the human health and water environment. Therefore, these substances, which are listed as prohibited chemicals on national and international lists, must be monitored permanently with regards to environmental and human health both in the water resources and potential receiving waterbodies. The objective of this study was to present the method for the sensitive and accurate determination of some volatile aromatic hydrocarbons (VAHs), including quite dangerous substances such as benzene, toluene, xylenes, styrene and chlorobenzenes by using gas chromatography -mass spectrometry (GC-MS) with purge & trap (PT) process in different water samples. The proposed method was verified with the selectivity, linearity, limits of detection and quantification (LOD and LOQ), precision studies of the method and instrument. All analytes examined in the study were trustworthily measured within the maximum performance limits for PT-GC-MS. The selectivity work was carried out by duplicate analysis of six blank water samples. There is no finding or observation within the interval of the retention time of the analytes in the water samples. The linearity of calibration curves was drawn by analysis of prepared standard solutions at nine concentration levels. The analytical response linearity in the working range can be assessed as an excellent since the correlation coefficients higher than 0.9996 for all analytes. The method accuracy was carried out by doing recovery experiment. Recoveries of analytes have been changed from 88.4 % to 94.6 % and the relative standard deviation (RSD) results were found between 3.52 % and 6.35 %. The applicability of developed method was confirmed by the determination of related analytes in the water samples.Özet. Endüstriyel faaliyetlerin sonucunda çok çeşitli kimyasallar ortaya çıkmaktadır. Bunlar, insan sağlığı ve su ortamı üzerinde oldukça toksik ve kanserojenik etkilere sahip olabilirler. Bu nedenle, ulusal ve uluslararası listelerde yasaklanmış kimyasallar olarak yer alan bu maddeler, hem su kaynakları hem de potansiyel alıcı su ortamlarında çevre ve insan sağlığı açısından sürekli olarak izlenmelidir. Bu çalışmanın amacı, farklı su örneklerinde tasfiye & tutma (PT) işlemi ile gaz kromatografisikütle spektrometresi (GC-MS) kullanılarak benzen, toluen, ksilenler, stiren ve klorobenzenler gibi oldukça tehlikeli maddeler içeren bazı uçucu aromatik hidrokarbonların (UAH'lar) hassas ve doğru tespitine yönelik yöntemi sunmaktır. Önerilen metot, seçicilik, doğrusallık, tespit ve tayin limitleri (LOD ve LOQ), metot ve cihazın kesinlik çalışmaları ile doğrulanmıştır. Çalışmada incelenen tüm analitler, PT-GC-MS için maksimum performans sınırları içinde güvenilir şekilde ölçülmüştür. Seçicilik çalışması, altı boş su örneğinin çift analizi ile gerçekleştirilmiştir. Su örneklerindeki analitlerin alıkonma süreleri arasında herhangi bir bulgu veya gözleme rastlanmamıştır. Kalibrasy...
