In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...

The catalytic activity of Pd/ZrO2 was studied in terms the degradation rhodamine-B dye presence hydrogen peroxide. prepared by impregnation method, calcined at 750 °C and characterized XRD, SEM EDX. catalyst showed good for 333 K, using 0.05 g during 5 h. reaction kinetics followed pseudo-first order kinetics. Freundlich, Langmuir Temkin isotherms were applied to data best fit obtained with Fre...

ultrasonic-assisted method was applied for preparation of cu+2-doped zns nanoparticles (mole fractions of cu+2 ions are 0.000, 0.015, 0.030 and 0.060) in water as a template-free and green method at 30 min. the prepared nanoparticles were investigated by powder x-ray diffraction (xrd), scanning electron microscopy (sem), energy dispersive x-ray (edx) and uv–vis diffuse reflectance spectra (drs)...

Accelerated degradation is the increased breakdown of a pesticide upon its repeated application, which has consequences for the environmental fate of pesticides. The herbicide atrazine was repeatedly applied to soils previously untreated with s-triazines for >5 years. A single application of atrazine, at an agriculturally relevant concentration, was sufficient to induce its rapid dissipation. S...

In both mice and humans alternate splicing results in isoforms of c-Kit characterized by the presence or the absence of a tetrapeptide sequence, GNNK, in the juxtamembrane region of the extracellular domain. Dramatic differences in the kinetics and magnitude of activation of the intrinsic tyrosine kinase activity of c-Kit between the GNNK- and GNNK+ isoforms has previously been shown. Here we r...

Environmental presence and retention of commonly used neonicotinoid insecticides such as dinotefuran (DNT), imidacloprid (IMD), and thiamethoxam (THM) is a cause for concern and prevention due to their potential toxicity to non-target species. In the present study the kinetics of the photodegradation of these insecticides were investigated in water and soil compartments under natural light cond...

Advanced Oxidation Processes (AOP) using ozone, H2O2, ultrasound (US), ultraviolet radiation (UV), Fenton’s reagent (FeII+H2O2) alone or in combination involving hydroxyl radicals are considered as possible methods of clean and ecologically safe remedial treatment for the degradation of organics. In the present study, comparison of kinetics of photochemical, sonochemical and chemical oxidation ...
