Dielectric And Relaxation Time Characterization Of Bound Water On Hydrophilic And Hydrophobic Surfaces

Bound water plays an important role in the processing and utilization of numerous materials and mineral processing systems. The fundamental nature of this near surface bound (vicinal) water is yet to be understood in its complete detail. The objective of this paper is to use dielectric measurements to characterize the bound water near hydrophobic and hydrophilic oxide surfaces. It is anticipated that a combination of dielectric property measurements and characteristic relaxation times will allow for more effective analysis of the interfacial water.
