Perchloroethylene Analysis by Chemical Oxidation and Determination of Intermediate Products by Gas Chromatography, Mass Spectrometry

Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...
