Abstract
This report (Contract No. G0110303) gives the results of a study of the surface oh groups on oxide surfaces using internal reflection spectroscopy. Mgo-h2o interface was studied with internal reflection spectroscopy. Both atr and transmission techniques were employed. The chemisorption of oleic acid, octylamine, and deriphat 151 on hematite was studied, and the amount of chemisorbed species on the surface was compared with the recovery in flotation of hematite using the chemisorbing species as collectors. From the internal reflection spectra, it was not possible to determine whether the carboxyl groups of oleic acid are directly bonded to the surface metal ions or through the surface oh groups. A theoretical approach was developed whereby the chemisorption on different surface sites could be inferred from the measurements of the ph of zero electrophoretic mobility.
