Gas-phase degradation of CCl4, CHCl3 and CH2Cl2 over metallic Fe
Tóm tắt
We studied the hydrolysis of gas-phase carbon tetrachloride (CCl4), chloroform (CHCl3), and dichloromethane (CH2Cl2) over a metallic Fe surface for its application in combination with air stripping and soil vapour extraction. The effects of chlorocarbon concentration, type and preparation of the iron-containing material, humidity, and temperature on process performance are reported. The hydrolysis of chlorinated methane derivatives is catalysed by metallic iron resulting in a noticeable decrease of the reaction temperature. The reaction kinetics were found to be consistent with the Langmuir-Hinshelwood model.
