Sorption Removal of Fluorine Ions, Incoming with the Recycling Zinc-Bearing Materials
Abstract
The possibility of using inorganic sorbent, iron oxyhydrate (IOH) to remove F- ions from technological solutions of zinc production is considered in this article. The principal possibility of the use of ion-exchange resins as carriers modified by IOH is considered. The formation of the active substance on cation-exchange resins was studied. It was shown that the most durable composite sorbents were obtained using strong-acid cation-exchange resins with SO3-- groups. A method for introducing IOH into the structure of carrier materials and obtaining composite sorbents is described. The strong acid cation exchanger KU-2×8 is recommended as the basis of the composite.
