The kinetics of iodate formation is a critical factor in mitigation of the formation of potentially toxic and off flavor causing iodoorganic compounds during chlorination. This study demonstrates that the formation of bromine through the oxidation of bromi ...
Under air atmosphere, the photocatalytic discoloration of malachite green (MG) aqueous solutions (a triphenylmethane dye) in the presence of TiO2 and UV light followed an oxidative pathway, involving an N-demethylation process evidenced by a blue shifting ...
Bromate (BrO3–) in drinking water is traditionally seen as an ozonation byproduct from the oxidation of bromide (Br–), and its formation during chlorination is usually not significant. This study shows enhanced bromate formation during chlorination of brom ...
N,N-Dimethylsulfamide (DMS), a newly identified, ubiquitous degradation product of the fungicide tolylfluanide, has been shown to be a N-nitrosodimethylamine (NDMA) precursor during zonation. In this study, batch ozonation experiments in ultrapure buffered ...
As previously demonstrated by Thurber and Tycko, the peak position of Br-79 in potassium bromide (KBr) allows one to determine the temperature of a spinning sample. We propose to adapt the original design by using a compact KBr tablet placed at the bottom ...
Attempts to develop quantitative structure-activity relationships (QSARs) for reductive dehalogenation have been hindered by the unavailability of high quality predictor variables, have included relatively few compounds, and on occasion have relied on data ...
The formation of bromophenols during chlorination of phenol- and bromide-containing waters can be critical for taste and odour problems in drinking waters. The work performed has confirmed that flavour threshold concentrations of some bromophenols are in t ...
In organic conductors the overlap integral between layers is small In-plane momentum scattering is rapid and transport perpendicular to the layers is expected to be blocked We present a high frequency conduction electron spin resonance (CESR) study in the ...
Kinetics, products, and pathways of 17 alpha-ethinylestradiol (EE2) transformation during chlorination of water with and without bromide (Br-) were studied to evaluate the effect of chlorination on the fate of steroid estrogens. Br- can be important for th ...
The objective of this study was to analyze the efficiency of Ag-doped aerogels in the removal of bromide and iodide from water. To test the applicability of these aerogels in water treatment, adsorption of bromide and iodide was studied under dynamic condi ...
