Physical and Chemical Behavior of Chrysotile Asbestos Particles in Natural Waters

by Roger C. Bales, Univ of Arizona, Dep of Hydrology, & Water Resources, Tucson, AZ, USA,



Document Type: Proceeding Paper

Part of: Hydraulics and Hydrology in the Small Computer Age

Abstract:

The paper reports on research to develop a better understanding of the chemical behavior and the influence of surface chemistry on the physical behavior of chrysotile asbestos and other colloidal particles in natural waters and in water-treatment processes. The relation between dissolution, adsorption and surface-charge development is studied experimentally. Surface charge is interpreted in terms of a coordination-chemical model of adsorption at a hydrous-oxide surface.
