We report a new method for determining the 15N/14N of NH4+ at natural abundance level in both freshwater and seawater. NH4+ is first quantitatively oxidized to NO2- by hypobromite (BrO-) at pH approximately 12. After the addition of sodium arsenite t

Gamma radiolysis was used to degrade aqueous MTBE/BTEX mixtures and the results compared to kinetic modeling predictions. Under our experimental conditions all the BTEX compounds are degraded within 10 min while MTBE required irradiation times in exc

The reactions of hydroxyl radicals with methyl t -butyl ether (MTBE) were studied using gamma radiolysis. Aqueous solutions of 100 ppm MTBE were saturated with 4:1 N 2 O/O 2 gas mixture prior to irradiation. Under these conditions hydroxyl radical is
