Proton Adsorption onto Alumina: Extension of Multisite Complexation (MUSIC) Theory

“…This inconsistency may be due to the assumption that positively charged oxo groups were absent, whereas the result is consistent with the relatively high site density that the model predicted (2.4 site/nm 2 ). Electrophoresis measurements of high-purity ␣-alumina powders confirmed their IEP's at pH 3.3 to 4.8 in 10 Ϫ3 M KNO 3 aqueous solutions (28). Also, magnetic fine powder (NiO ⅐ ZnO ⅐ Fe 2 O 3 ) showed a similar tendency of a low IEP (29).…”
