One of the most important properties of zeolitized volcaniclastic materials is the cation exchange capacity (CEC). Numerous techniques are available for measuring CEC and the methylene blue absorption (MBA) (Nevins & Weintritt, 1967) and the ammonium acetate saturation (AMAS) (Chapman, 1965) methods are two of those commonly used. The aim of this study was to compare the results obtained by the two methods when used with zeolite-rich materials.
