Effects of pH on Dielectric Relaxation of Montmorillonite, Allophane, and Imogolite Suspensions

Dielectric measurements were performed on montmorillonite, allophane, and imogolite suspensions under various pH conditions, using time domain reflectometry over the frequency range 10 kHz–20 GHz. A dielectric relaxation peak due to bound water could be observed for all the clays. Allophane has two...
