چکیده انگلیسی
The electrokinetic potentials of anatase (titanium dioxide) and α-alumina were studied by means of various instruments in the presence of sodium and potassium trichloroacetates, trifluoroacetates, and trifluoromethanesulfonates at various pH, ionic strengths, and solid-to-liquid ratios. At concentrations up to 0.01 M, these salts do not induce substantial shifts in the isoelectric point of the oxides. Such behavior is typical of inert electrolytes.
The zeta potential of anatase (titanium dioxide) in 0.001 M solutions of 1–1 salts as measured by means of electrophoresis. The electroacoustic method produced similar results.Figure optionsDownload as PowerPoint slide
