摘要: ABSTRACT The kinetics of oxidation trichloroethylene (TCE) by potassium permanganate (KMnO4) was investigated in a phosphate buffer solution pH 7 and ionic strength (I) 0.05 M at three different temperatures (10, 15, 20°C). results indicate that the TCE KMnO4 constant temperature may be modeled as an irreversible second-order (first-order individually with respect to TCE) reaction. rate activation energy, determined using initial method for reaction between KMnO4, were 0.89 ± 0.03 M−1s−1 35 2.9 kJ/mol, respectively. this study also confirmed assumed stoichiometry, i.e., 2 mol are required mineralization 1 TCE. Key words: Potassium permanganate; TCE; trichloroethene; oxidation; kinetics; rate; energy; remediation; ethene
