Sonocatalytic degradation of humic acid by N-doped TiO2 nano-particle in aqueous solution
BACKGROUND Un-doped and N-doped TiO2 nano-particles with different nitrogen contents were successfully synthesized by a simple sol-gel method, and were characterized by X-ray diffraction, field emission scanning electron microscopy, Energy dispersive X-ray analysis and UV-visible diffuse reflectance spectra techniques. Then enhancement of sonocatalytic degradation of humic acid by un-doped and ...
متن کاملPhotoelectrocatalytic degradation of humic acid in aqueous solution using a Ti/TiO2 mesh photoelectrode.
Humic acid (HA) is one of natural organics existing in water supply as a precursor of trihalomethanes formation in chlorination. The photo-degradation of HA in aqueous solution by photoelectrocatalytic (PEC) oxidation using a Ti/TiO2 mesh electrode was investigated in terms of UV absorbance at 254 nm, colour and TOC concentration. The key factors affecting the PEC oxidation efficiency were stud...
متن کاملاکسیداسیون سونوکاتالیستی رنگ راکتیو بلو 29 توسط نانو ذرات N-doped TiO2 از محیط آبی
Background and purpose: Sonocatalytic process as an advanced oxidation process is considered for degradation of pollutants in aqueous solution. The aim of this study was to increase the removal of dye by doping of TiO2 with non-metal element such as nitrogen. Materials and methods: Un-doped and N-doped TiO2 nano-particles with different nitrogen contents were synthesized by a simple sol–gel me...
