Optimization of sonochemical degradation of tetracycline in aqueous solution using sono-activated persulfate process
BACKGROUND In this study, a central composite design (CCD) was used for modeling and optimizing the operation parameters such as pH, initial tetracycline and persulfate concentration and reaction time on the tetracycline degradation using sono-activated persulfate process. The effect of temperature, degradation kinetics and mineralization, were also investigated. RESULTS The results from CCD ...
متن کاملPhotocatalytic Degradation of Bisphenol A from Aqueous Solutions using TiO2 Nanoparticles and UV Illumination
Background and Purpose: Bisphenol A (BPA) is used to make certain plastics and epoxy resins. It is a non-biodegradable compound, and poses health risks to both humans and animals. The purpose of this study was to evaluate decomposition efficiency of BPA from aqueous solutions using UV irradiation. Materials and Methods: In this study, the photodegradation of BPA in water were carrie...
متن کاملRemoval of phenol from aqueous solutions using persulfate-assisted, photocatalytic-activated aluminum oxide nanoparticles
The combination process of UV/ S2O82-/Al2O3 leads to the production of radicals and radical hydroxyls, which could decompose and remove various pollutants, such as phenol. The present study aimed to investigate the photocatalytic efficiency of aluminum oxide nanoparticles and persulfate compilative processes in the removal of phenol. This e...
متن کاملSonochemical synthesis of nanosized hollow hematite.
Hollow inorganic materials are of great interest, in part because of their diverse applications for drug delivery, catalysis, photonic crystals, etc.1 Various preparation methods have been developed to fabricate hollow inorganic materials2,3 and even hollow single crystals;4 most commonly these synthetic methods exploit the use of silica nanospheres as a sacrificial template material. While sil...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
