A full-scale ozonation reactor was characterised with respect to the overall oxidation budget by coupling laboratory kinetics with reactor hydraulics. The ozone decomposition kinetics and the ratio of the OK radical to the ozone concentration were determin ...
The performance of the electrolytic ozone generation using a solid polymer electrolyte (SPE) and Pb anode is described. This anode has been prepd. by application of Pb powder on a porous Ti substrate coated with IrO2 layer (Ti/IrO2/Pb anode). Electrochem. ...
Ozone prodn. in 5M H2SO4 with Ti/IrO2/SnO2 - Sb2O5 electrodes was studied. Electrodes were prepd. at 550 Deg by spray pyrolysis of a soln. of precursors contg. tin and antimony chlorides. The aim of this work was to elucidate the mechanism of activation an ...
We studied a new approach to cell ashing based on illuminating the specimens with a low-pressure mercury discharge lamp. We analyzed with synchrotron spectromicroscopy its effects on different physiological elements in neurobiological specimens. Our result ...
From a data set collected during the MEDCAPHOT-TRACE field campaign, we demonstrate that ozone fluxes can be detd. with a shot-per-shot DIAL instrument operated in the UV spectral region. This is done by the simultaneous reconstruction of ozone concns. and ...
In aqueous oxidative processes with ozone (O-3), chlorine, or chloramine, naturally occurring iodide (I-) can easily be oxidized to hypoiodous acid (HOI) which can react with natural organic matter (NOM) or he further oxidized to iodate (IO3-). Such proces ...
Measurements of local air pollution and road traffic were taken during a period of one month before and after the opening of a road tunnel to the public in nearby Sachseln, a small city located in a rural region (Obwald) at the center of Switzerland. Two 5 ...
Full-scale ozonation processes for drinking water production were characterized with a conservative (sodium chloride) and two reactive tracers (ozone, aqueous chlorine) to yield information about the hydraulics and the oxidation capacity with respect to or ...
Ferroelectric, dielectric and piezoelectric properties of ferroelectric thin films and ceramics are reviewed with the aim of providing an insight into different processes which may affect the behaviour of ferroelectric devices, such as ferroelectric memori ...
Bromate formation in ozone-based advanced oxidation processes (AOPs) was investigated by laboratory experiments in combination with kinetic modeling. Oxidant concentrations were monitored during the experiments, which allows us to account for the relative ...
