Membrane introduction mass spectrometry applied to the monitoring of chloroform degradation by hypochloride in acidic aqueous medium

摘要

Membrane Introduction Mass Spectrometry (MIMS) was used to investigate chloroform degradation in acidic aqueous medium by sodium hypochloride (NaClO). From the experimental results a reaction sequence for the complete degradation of CHCl3 to CO2 and HCl was suggested. Furthermore, it was also proposed the formation of phosgene (COCl2) as a transient species under these experimental conditions.
