Innovative Application of Electrokinetic Treatment on Montmorillonite Modification: Effects on pH, Current, and Swelling Properties of Ca-Montmorillonite
Source abstract
Abstract
This study evaluates the feasibility of converting Ca-montmorillonite into Na-montmorillonite through electroosmosis. Comprehensive analyses of current, pH, ζ-potential, and ethylene glycol expansion were conducted to investigate the macro- and microscale effects of electroosmosis. The results demonstrate that electroosmosis effectively reduces the swelling properties of montmorillonite. X-ray fluorescence (XRF) analysis revealed changes in the crystalline structure and interlayer charges, enabling the derivation of the chemical formula and a deeper understanding of the relationship between ζ-potential and interlayer charge.
