The project is aimed at developing the scientific and technological bases of highly efficient cavitation-activated advanced oxidation processes, including nanocatalytic, of biodegradation-resistant N-substituted organic pollutants of aqueous media.
popup.description2
The cavitational (in an ultrasonic field) modification of clinoptilolite with copper (I) oxide (Cu2O) nanoparticles/copper (II) oxide (CuO) nanoparticles was carried out to provide natural aluminosilicate (clinoptilolite) with sorption, photocatalytic, and antibacterial properties. To purify aqueous environments from the monoazo dye Acid red 14, the advanced oxidation process “ultrasonic cavitation/Cu2O nanoparticles@clinoptilolite/potassium periodate” was developed, which combined two strategies for activating the oxidizing agent (potassium periodate): in an ultrasonic cavitation field and by the synthesized catalyst (Cu2O nanoparticles@clinoptilolite). The antifungal activity of the composite “Cu2O nanoparticles@clinoptilolite” against the anamorphic yeast Candida utilis ATCC 9950 was evaluated using the disk diffusion method by the growth inhibition zones. By the method of direct introduction of the composite “CuO nanoparticles@clinoptilolite” into the nutrient medium, the high antibacterial activity of the composite against the gram-positive bacterium Staphylococcus aureus subsp. aureus ATCC 25923 and the dependence of the effectiveness of the antibacterial action on the duration of exposure were established. Samples of clinoptilolite modified with copper oxide nanoparticles and waste from thermal power plants (fly ash) were tested as components of energy-condensed mixtures for the generation of aerosols with masking properties in the visible and infrared ranges of the optical spectrum. The scientific and technological foundations of environmentally friendly, highly efficient, and highly intensive flexible cavitation-activated advanced oxidation processes of the bio-resistant N-substituted organic compounds (dyes, antibiotics) based on periodates/sodium percarbonate/persulfates/sulfites/Fenton-like systems have been developed. A feasibility study of the effectiveness of the developed processes was performed.
