The effects of dry and wet oxidation treatments activated carbon (AC) on the surface chemistry porous structure are studied. Using cherry stones (CS), AC was first prepared by carbonization at 900 °C for 2 h in N2 activation 850 CO2. Then, resulting oxidized O2(air) or O3 atmosphere with HNO3 H2O2 solutions. acidic–basic sites were analyzed FT-IR spectroscopy, Boehm method, pH point zero charge (pHpzc) adsorption mercury porosimetry. It has been found that oxidizing agent, under specific...
Abstract Ozone decomposition in water the presence of an activated carbon has been studied. Variables investigated were agitation speed, particle size, temperature and pH. In all cases, improved ozone rate. Between pH 2 7 rate due to both homogeneous heterogeneous mechanisms hardly varied while a significant increase was noticed with increasing A kinetic study based on Langmuir-Hinselwood type mechanism for surface reaction undertaken. According this kinetics can be simplified follow first...
The ozonation kinetics of oxalic acid in water the presence an activated carbon has been investigated at pH. significantly enhances degradation rate if compared to single and adsorption. According total organic measurements, nearly complete mineralization can be achieved depending on experimental conditions. tert-butyl alcohol, which scarcely adsorbs surface conditions investigated, led a significant reduction removal rate. Consequently, results suggest that reaction proceeds phase between...
A novel green method has been investigated to obtain a magnetic recoverable photocatalyst. Fe3O4 particles formed in situ by aerial oxidative precipitation of aqueous Fe(II) the presence terephthalate were bonded TiO2-P25 nanoparticles, giving rise coupled semiconductor heterostructure with superparamagnetic behavior at room temperature (Fe3O4 @TiO2-P25). The synthesis is carried out water almost full recovery and recycling terephtalic acid. prepared samples fully characterized XRD,...
