Under mild conditions, potassium permanganate can effect conversion of alkenes to glycols. As mentioned above, activated carbon is not effective for all chemical gases. The oxidation of microcystin-LR (MC-LR) in deionized water (DI) and river water using potassium permanganate (KMnO 4 ) at a neutral pH and at 23 ± 2 °C was investigated. Features a consistent density, is economical and has minimal dust generation. Such procedures should comply with all applicable Local, State and Federal guidelines. //
