高锰酸钾降解地下水中PCE的研究
Oxidation of terachloroethylene in groundwater with permanganate
摘要
Abstract
As one of the widely existent pollutant,terachloroethylene(PCE)was chosen as the aim pollutant,and the self-made permanganate solution was chosen as oxidant.The batch experiment method was used to investigate the reaction kinetics,influencing factors and dechlorination mechanism of PCE.Experimental results have shown that the reaction appears to be first order and has an activation energy of 57.119 kJ/mol.The reaction rate constant Kobs was 0.0076 min-1 and the half-life t1/2 was 91.20 min at 30℃.The reaction rate constant of PCE was almost not affected by pH(3～10)and ionic strength(0～0.1030 mol/L).关键词
