Oxidation of microcystins by permanganate: Reaction kinetics and implications for water treatment

Permanganate oxidation of diclofenac: The pH-dependent reaction kinetics and a ring-opening mechanism

“…3, the ln k values exhibit a good linearity (R 2 = 0.99) with the reciprocal of temperature (1/T). The activation energy of the Mn(VII)/DCF reaction was then calculated to be 26.2 ± 0.4 kJ mol À1 , which is comparable to that of Mn(VII)/dichlorvos (29.5 kJ mol À1 ) and Mn(VII)/microcystins (28.8 kJ mol À1 ) reactions (Rodríguez et al, 2007;Liu et al, 2009).

Fresh Water Savings Through the Use of Municipal Effluents in Concrete Pavement

“…Furthermore, potassium permanganate has been widely used in water and wastewater treatment to control taste and odor, remove color, control biological growth in treatment plants, remove polycyclic aromatic hydrocarbons which have a carcinogenic and/or mutagenic potential (de Souza e Silva et al, 2009;Rodríguez et al, 2007); and potassium permanganate has several additional advantages such as easier to handle, readily soluble and higher efficiency in water and soil treatment over other oxidants (Xu et al, 2005;Yan and Schwartz, 1999). Unlike oxone, potassium permanganate gained momentum over a century ago and has increased in use due to its eco-friendly water/wastewater treatment applications around the world as well as its low cost (Dash et al, 2009;Kao et al, 2008).…”

Cyanotoxins in Serbia and water treatment procedures for their elimination

“…Compared to other oxidants, permanganate is sometimes preferred because of its relatively low cost, ease to handle, effective over a wide pH range, and stabile in the subsurface (Waldamer, Tratnyek, 2006). Oxidation of organic matter using permanganate does not lead to the formation of chlorinated or brominated byproducts (Rodriguez, et al, 2007a).…”
