摘要：
The reaction mechanisms and rate constants of N, N-diethylhydroxylamine (DEHA) with ·OH, CO3−·, eaq− and ·H were studied. Results show that ·OH radicals oxidize DEHA by hydrogen abstraction from DEHA’s hydroxyl group to form transient (C2H5)2NO·, which has an absorption maximum at 395 nm. The transient intermediates for the reactions of DEHA with CO3−· and eaq−, as well as protonated DEHA with ·H, show no absorption peak between 300 and 800 nm. The rate constants for the reactions of DEHA with ·OH, CO3−· and eaq−, also protonated DEHA with ·H, were measured.
