“…The light used in the experiment was solar light and UV-A light. The batch photocatalytic system in this study was exposed to direct sunlight with an intensity of 76-72 kW and UV-A light with a light density of 6 W. The parameters studied in this experiment include pH different [3] , [5] , [7] , concentration of TiO 2 /β-Bi 2 O 3 nanocomposite as a catalyst (0.05, 0.1, 0.3, 0.4 g/L), hydroxychloroquine concentration (1, 10, 20, 40 mg/L), H 2 O 2 concentration (1,2, 3, 4 mg.L -1 ), temperature (10, 20, 40, and 60 ˚C) and irradiation time (5,10,15,20,30,45,60,90,120min). (0.1 M) HCl and (0.1 M) NaOH were used to adjust the pH, and a magnetic stirrer at 70 rpm was used to blend the system.…”

“…Long-term use of hydroxychloroquine (HCQ) is a cornerstone in the treatment of this disease [2] . However, the entry of substances containing these pharmaceutical compounds into the environment occurs through the wastewater of the pharmaceutical industry, hospital effluents, and effluents from wastewater treatment plants, laboratory activities, and human and animal wastes [3] . The use of HCQ is causing unanticipated harm to the environment.…”

Mesoporous silica (SBA-15 with the BJH pore size of 8 nm) containing anatase nanoparticles in the pore with two different titania contents (28 and 65 mass%), which were prepared by the infiltration of the amorphous precursor derived from tetraisopropyl orthotitanate into the pore, were heat treated in air to investigate the structural changes (both mesostructure of the SBA-15 and the phase and size of the anatase in the pore). The mesostructure of the mesoporous silica and the particle size of anatase unchanged by the heat treatment up to 800 °C. The heat treatment at the temperature higher than 1000 °C resulted in the collapse of the mesostructure and the growth of anatase nanoparticles as well as the transformation to rutile, while the transformation of anatase to rutile was suppressed especially for the sample with the lower titania content (28 mass%). The resulting mesoporous silica-anatase hybrids exhibited higher benzene adsorption capacity (adsorption from water) over those heated at lower temperature, probably due to the dehydroxylation of the silanol group on the pore surface. The photocatalytic decomposition of benzene in water by the present hybrid heated at 1100 °C was efficient as that by P25, a benchmark photocatalyst.

In this study, zinc oxide nanoparticles (nZnO) were synthesized, deposited, and successfully used for surface modification of cotton to enhance antimicrobial properties. An in situ ultrasonic acoustic method was applied to anchor nZnO on cotton. The results of scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction confirmed the presence of nZnO on cotton. A homogenous distribution of nZnO with an average particle size 27.4 nm was found during the analysis of results. Antimicrobial performance of cotton-nZnO (C-nZnO) composites was evaluated against Gram-negative and Gram-positive microbes. The deposited amount of nZnO on C-nZnO composites was determined by volumetric titration through inductive couple plasma atomic emission spectroscopy. C-nZnO composites showed excellent antimicrobial performance especially against both Staphylococcus aureus (Gram-positive) and Escherichia coli. The durability and stability of C-nZnO composites were tested against leaching and washing. No significant fluctuation was found on deposited amount of nZnO before and after washing test for optimized sample. The results demonstrate that synthesized C-nZnO composite samples can be used as an alternative for antimicrobial bandages.
