“…Heretofore, adsorption, ion exchange, biological method, advanced oxidation processes (AOPs) have been employed as instrumentalities for UDMH polluted wastewater purification. Nevertheless, the practical application of above methods were hindered by their inherent demerits [3,[6][7][8][9].…”

Releasing unsymmetrical dimethyl hydrazine (UDMH) in ambient medium is an escalating environment crisis that catches aggrandizing public concerns. Herein, a non-thermal plasma activating persulfate maneuver was introduced and its application mechanism in UDMH degradation was explored.Oxidizing kinetic experiments show that 93.8% UDMH were eliminated along with 12.5 kV, pH = 8, 50 mM NaCl, Na 2 S 2 O 8 /UDMH (mol/mol) = 2, and 140 mL/min. The Visual MINTEQ simulated species distribution of UDMH well predicted the oxidation behaviors of UDMH in the variation of pH. Radical scavenging test integrated with UV-vis spectroscopy were introduced to identify the predominating reactive oxygen species during UDMH decomposition. The •OH and •SO 4 played a synergistic role in the UDMH oxidization. Overall, this study may shed new lights on the degradation of UDMH industry wastewater using hybrid technique.
