WebA permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) is a chemical compound containing the manganate(VII) ion, MnO − 4, the conjugate base of permanganic acid.Because the manganese atom is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent.The ion is a transition metal oxo complex with tetrahedral geometry. … WebThe oxidation-reduction thermodynamics for the manganese(III), -(IV), and -(II) ions, and their various complexes, are reviewed for both aqueous and aprotic media. In aqueous solutions the reduction potential for the manganese(III)/(II) couple has values that range from +1.51 V vs. NHE (hydrate at pH 0) to −0.95 V (glucarate complex at pH 13.5).
WebManganese removal from water via ion exchange is common in chemical and petrochemical processing, oil refining, semiconductor manufacturing and power utility plants. In waters with low levels of dissolved salts, a strongly acidic cation exchanger such as AmberSep™ G26 H Resin is employed. Weak acid cation exchange resins such as … WebMaterials 2010, 3 457 where, qe is the amount of the metal ions adsorbed at equilibrium per unit weight of sorbent (mg·g –1); q is the amount of metal ions adsorbed at any time (mg·g–1).Besides, kad is the rate constant min–1. Integrating and applying boundary conditions, t = 0 and qt = 0 to t = t and q = qt, Equation 1 takes the form: ln()qe −qt =lnqe …
