Metodo para la recuperacion de molibdato en una deslignificacion catalizada por molibdato de pulpa con peroxido de hidrogeno |
摘要 |
In a delignification of pulp with hydrogen peroxide catalyzed by molybdate, molybdate can be recovered by contacting the molybdate-containing aqueous solution at a pH in the range from 2 to 7 with a carrier material comprising a sheet silicate been ion-exchanged with a quaternary ammonium salt and subsequent flotation without a surfactant having to be added for flotation. |
