The dynamic behavior caused by hydro-adsorption process of materials based on arich mineral clinoptilolite together with their acidic, basic and calcinated forms has been studied by the dynamic laser speckle (DLS) technique. We propose a modifiedPeleg?s equation to improve fitting of DLS data. Textural (BET), structural (XRD)and spectroscopic (FTIR) properties were also studied and compared. We demonstratedthat DLS was the most sensitive, simple and inexpensive method for comparingthe performance of adsorptive materials with slightly modified surfaces. It alsoallowed the correlation with physicochemical properties.
