[Technical Column] Ion Exchange Capacity

Explanation of preprocessing, sampling, and measurement procedures! The exchange capacity varies depending on the type of ion exchange resin.

An important item for evaluating the performance of ion exchange resins is "ion exchange capacity." The ion exchange capacity of standard cation exchange resins is about 2 equivalents per liter. The amount that can be adsorbed varies by element; for sodium ions, it is 46g per liter of cation exchange resin, for magnesium ions, it is 24g, and for cesium ions, it is 266g. In this column, we introduce topics such as "the relationship between the types of ion exchange resins and their exchange capacity" and "the measurement procedures for ion exchange capacity."
