Oxidation of chlorinated ethenes by potassium permanganate: a kinetics study
The kinetics of oxidation of perchloroethylene (PCE), trichloroethylene (TCE), three isomers of dichloroethylene (DCE) and vinyl chloride (VC) by potassium permanganate (KMnO 4) were studied in phosphate-buffered solutions of pH 7 and ionic strength ∼0.05 M and under isothermal, completely mixed and...

| description | The kinetics of oxidation of perchloroethylene (PCE), trichloroethylene (TCE), three isomers of dichloroethylene (DCE) and vinyl chloride (VC) by potassium permanganate (KMnO
4) were studied in phosphate-buffered solutions of pH 7 and ionic strength ∼0.05
M and under isothermal, completely mixed and zero headspace conditions. Experimental results have shown that the reaction appears to be second order overall and first order individually with respect to both KMnO
4 and all chlorinated ethenes (CEs), except VC. The degradation of VC by KMnO
4 is a two-consecutive-step process. The second step, being the rate-limiting step, is of first order in VC and has an activation energy (
