摘要：

In this work we present a study of the interactions of multiple reactant ions (RI) generated in corona discharge (CD) with molecules of 2,4,6-trinitrotoluene (TNT) using the ion mobility orthogonal-acceleration time of flight mass spectrometry (IMS-oaTOF) technique. We have studied response of TNT molecules to different reactant ions (RI) such as O-2(-), Cl-, N2O2-, NO3- or NO3-center dot(HNO3). The response of TNT to RI results in formation of multitude of species, such as TNT-, (TNT-H)(-) and cluster ions. Additionally, we have investigated the stability of TNT- ions as function of IMS gas temperature and drift field intensity and their conversion to (TNT-H)(-). Formation of some product ions was assigned to degradation of TNT by neutral reactive species generated by the CD. (C) 2015 Elsevier B.V. All rights reserved.
