摘要

Cyanogen chloride(CNCI)is a disinfection byproduct found in chlorinated and chloraminated drinking water.Although there is an apparent greater association of CNCI with chloraminated water relative to chlorination systems,it was not clear whetherthese phenomenological observations are explained by differences in the stability or formation potentials of CNCI between the two disinfectants.In this study,the stability of CNCI was examined in the presence of free chlorine and monochloramine using membrane introduction mass spectrometry.CNCI decomposes relatively rapidly when free chlorine is present but is stable in the presence of monochloramine.
