Patent ID: 7232782

Claim:
A method of rapid and adaptive regeneration of loaded oxides of manganese particles bearing manganese salt reaction products on the surface of the particles, the reaction products being formed by reaction between target pollutants and virgin oxides of manganese, comprising the steps of: rinsing the loaded oxides of manganese in a pre-oxidation aqueous rinse solution to dissolve reaction products into solution, thereby removing reaction products from the surface of the oxides of manganese; separating or filtering the rinsed oxides of manganese from the solution, the solution being directed as a pre-oxidation filtrate for further processing or handling; feeding the rinsed oxides of manganese into a regeneration vessel containing a heated aqueous oxidizing solution under agitation and mixing the solution to form a slurry, the solution being prepared so as to have Eh and pH values within the MnO2 stability area for an aqueous solution heated to a temperature at or near boiling temperature at atmospheric pressure; monitoring and adjusting solution temperature, Eh value and pH value so as to rapidly move solution conditions into and to maintain them within the MnO2 stability area; and maintaining the solution conditions within the MnO2 stability area until the oxides of manganese are regenerated so as to have pollutant loading capacity and/or average oxidation states at least equal to that of the virgin oxides of manganese with which the target pollutants were reacted.
