N-Nitrosamines Formation from Secondary Amines by Nitrogen Fixation on the Surface of Activated Carbon

摘要: Our previous study demonstrated that many commercial activated carbon (AC) particles may catalyze transformation of secondary amines to yield trace levels N-nitrosamines under ambient aerobic conditions. Because the widespread usage AC materials in numerous analytical and environmental applications, it is imperative understand reaction mechanism responsible for formation nitrosamine on surface ACs minimize their occurrence water treatment systems during methods employing ACs. The results show AC-catalyzed requires both atmospheric oxygen nitrogen. AC’s reactive sites react with molecular form species (ROS), which facilitate fixation nitrogen surfaces generate (RNS) likely nitrous oxide hydroxylamine can adsorbed nitrosamines. properties play a crucial role as more as...
