Abstract
Water-insoluble hydroxy double salts show pH-dependent surface-charging similar to that of metal oxides. While the pH-dependent surface-charging of metal oxides is very well-documented, the number of scientific papers reporting on the surface-charging of hydroxy double salts is limited. A collection of isoelectric points IEP of hydroxy double salts taken from the literature is presented. Electrokinetic behavior of paratacamite Cu2Cl(OH)3 was studied experimentally, and its IEP was at pH about 8.5.
