Abstract
The influence of solvation interactions on the surface charge of titania
powders was studied by means of linear solvation energy relationships
(LSER). The zeta potential (ZP) of titania powders and the effect
of water content were determined in a series of alcohols, including
methanol, ethanol, I-propanol, isopropanol, and 1-butanol. The ZPs
against the solvents' 13 LSER descriptors were analyzed by principal
component analysis (PCA), cluster analysis, multiple linear regression
(MLR), and stepwise multiple regression (SMR). Very good correlation
between ZP and LSER parameter was obtained. One LSER parameter, relative
dielectric constant, epsilon, was used to establish the LSER equation.
The ZP of titania powders in pure alcohols can be reasonably calculated
by an empirical formula: ZP = 13.43 - 213.63 . 1/epsilon. The results
show that epsilon is the most important factor governing the ZP of
titania powders. The results also suggest that the effect of solvation
interactions on ZP is a result of the electrostatic interactions
between powders and solvents. (C) 2003 Elsevier Science (USA). All
