Reductive degradation of azo dyes in aqueous solution by zero-valent iron
Kinetics of zero-valent iron remediation of two azo dyes in aqueous solution were investigated. Both show pseudo first-order reaction kinetics. Typical apparent reaction rate constants (k) are 0.70 min"' at 33.3 revolutions per second, k decreases with both increased pH and initial dissolved oxygen content increased over 5 mg l", but increases with both increasing iron conc entration and mixin...
متن کاملSonocatalytic degradation of p-chlorophenol by nanoscale zero-valent copper activated persulfate under US irradiation in aqueous solutions
In this study, nanoscale zero-valent copper (nZVC) as catalyst activated persulfate (PS) was used for the degradation of p-chlorophenol (p-CP) under ultrasonic (US) irradiation in aqueous solution. The effect of different operational parameters such as solution pH (3.5-10.5), PS concentration (1-7.5 mm/L), nZVC dosage (5-35 mg/L) and initial p-CP concentration (10-100 mg/L) were evaluated at di...
متن کاملSonochemical degradation of azithromycin in aqueous solution
Background: The presence of pharmaceutical substances and their residual in water resources is an important environmental concern. Azithromycin, an antibiotic that is used for the treatment of infectious diseases, is a pollutant agent in the wastewater. The aim of this study was to investigate azithromycin degradation in aqueous solution through ultrasonic process in the presence of zinc oxide ...
متن کاملZero Valent Iron (ZVI) nanocomposite for the removal of hexavalent chromium from aqueous solution
S. Ponmani and C. Udayasoorian Abstract -A new class of nano scale zero valent iron (nZVI) particles supported on activated carbon (AC) were synthesized and the feasibility of using nanocomposite (AC+nZVI) for the removal of Cr(VI) in water was investigated through laboratory batch test. Nanocomposite was synthesized by impregnating carbon with ferrous sulfate followed by chemical reduction wit...
متن کاملEfficient Fenton like degradation of Methylene blue in aqueous solution by using Fe3O4 nanoparticles as catalyst
Fe3O4 nanoparticles were prepared hydrothermally and characterized by X-Ray diffraction spectroscopy (XRD), and scanning electron microscopy (SEM). It was found that these nanoparticles can act as an efficient catalyst in the degradation of Methylene blue dye in aqueous solution in a Fenton like system in presence of 30% perhydrol. Uv-Vis spectroscopy was used to determine the concentration of ...
