WebDec 1, 2016 · The pH value of Al 2 O 3 nanofluids is adjusted by HCl and NaOH solutions and then their zeta potentials were measured. As shown in Fig. 5, for the fluid without dispersant, the zeta potential is zero when the pH of Al 2 O 3 fluid is 8, which is the isoelectric point (iep). When the pH value is greater than 8, the particle surfaces begin to ... In chemistry laboratories, aluminium oxide is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations.
