| titleOfInvention | A kind of technique that ion-exchange removes molybdenum from tungstate solution |
| abstract | The invention discloses the techniques that a kind of ion-exchange removes molybdenum from tungstate solution.The technique realizes the deep purifying of high-content molybdenum in such a way that two sections of vulcanization-resin adsorptions remove molybdenum.It is handled by first cure, in the lower situation of vulcanizing agent dosage, so that most molybdenums in solution is changed into two thiomolybdates and three thiomolybdates, then remove molybdenum by one section of absorption and molybdenum most of in solution is adsorbed to resin；Remaining a small amount of molybdenum in solution, vulcanized by second segment depth, in the excessive situation of vulcanizing agent dosage, is changed into molybdenum and the stronger tetrathio molybdate of strong-base anion-exchange resin affinity, again by the way of vacuum volatilization, the vulcanizing agent of liquid surplus after vulcanization is removed and recycled；Liquid after Vacuum Desulfurization realizes the deep removal of molybdenum by two sections of absorption except molybdenum is purified liquid. |
