摘要：
An ion-exchange separation method for alkaline earth metal ions (Mg2+, Ca2+ and Sr2+) is described. The highly selective separation of Mg2+ from Ca2+ and Sr2+ has been achieved with a strongly acidic cation exchange resin (Amberlite 200CT) in the presence of cryptand [2.2.1] as the ion-size selective masking reagent. The quantitative separation of Sr2+ from Mg2+ and Ca2+ could be achieved using Amberlite 200CT in the presence of cryptand [2.2.2].
