Process for preparing heterodisperse chelating resins

摘要

The object of the present invention is a process for preparing novel heterodisperse chelating resins having chelating functional groups, and their use for adsorbing metal compounds, in particular alkaline earth metals, heavy metal compounds and precious metal compounds, and also for extracting alkaline earth metals from saline solutions derived from alkali metal chloride electrolysis, and also in hydrometallurgy.
