dc.description.abstract | Oxidative degradation of six representative microcystins (MCs) (MC-RR, -LR, -YR, -LF, -LW, and -LA) by potassium permanganate (KMn0(4); Mn(VIl)) was investigated, focusing on the temperature- and pH-dependent reaction kinetics, the effect of dissolved organic matter (DOM), and the oxidation mechanisms. Second-order rate constants for the reactions of the six MCs with Mn(VII) (kappa(Mn(VII),MC)) were determined to be 160.4-520.1 M-1 s(-1) (MC-RR > -LR approximate to -YR > -LF approximate to -LW > -LA) at pH 7.2 and 21 degrees C. The kappa(Mn(VII),MC) values exhibited activation energies ranging from 15.1 to 22.4 kj mol(-1). With increasing pH from 2 to 11, the kappa(Mn(VII),MC) values decreased until pH 5, and plateaued over the pH range of 5-11, except for that of MC-YR (which increased at pH > 8). Species-specific second-order rate constants were calculated using predicted |
