N2 - The ζ-potentials of anatase at pH 2-11 in 0.1, 0.3, 0.5, and 1 moldm-3 NaI were studied using the DT 1200 in three laboratories. At [NaI]=1 moldm-3 the ζ-potentials were positive over the entire pH range. The previously observed tendency of the isoelectric point of anatase to shift to high pH at high ionic strength (M. Kosmulski, J.B. Rosenholm, J. Phys. Chem. 100 (1996) 11681) and the salt specificity of this effect were confirmed. The ζ-potentials obtained in different laboratories using DT 1200 are consistent within 3 mV. © 2003 Elsevier Science (USA). All rights reserved.
