摘要：
The results of batch and column ion-exchange experiments with a chromium tripolyphosphate glass and alkali metal ions are reported. The uptake, exchange capacity and log KD vary linearly with pH over a wide range. The glass is very selective towards alkali metal ions, which are adsorbed in the order Cs+ > Rb+ > K+ > Na+. The glass is suitable for column chromatography; the alkali metal ions can be separated after sorption by elution with 1 M hydrochloric acid. © 1969.
