Abstract

A radio frequency (RF) plasma system has been used to decompose 1,2‐dichloroethane (DCE). Final products were identified by a Fourier transform infrared (FTIR) spectrometer. The main products of DCE decomposition in O~2~/Ar plasma were CO~2~, CO, and HCl. Other minor chlorinated products were CCl~4~, C~2~HCl~3~, C~2~H~3~Cl, C~2~Cl~4~, CHCl~3~, C~2~HCl~5~, and COCl~2~. Nonchlorinated products were C~2~H~2~, C~2~H~4~, C~2~H~6~, and HCOOH. The plasma reactor with a brass electrode had a higher decomposition fraction of DCE [η, (C~in~ − C~out~)/C~in~ × 100%] than that obtained with other materials (Au, Ni, and Cr). Different electrode configurations (inner and outer) were also evaluated for the decomposition of DCE. Argon plus oxygen was found to be the most suitable carrier/auxiliary gas for DCE decomposition. In addition, operational parameters for DCE decomposition in RF plasma including concentration, operational pressure, and total gas flow rate were evaluated.
