Abstract:
The present invention relates to a method for improved removal of cations, preferably alkaline earth metals, in particular calcium and barium, from aqueous solutions using chelating resins having acetic acid and/or iminodiacetic acid groups having high dynamic absorption capacity for cations at a low residual content of the cations and high regeneration efficiency, to the chelating exchangers themselves, and also to uses thereof.
