Tóm tắt

HYPOTHESIS: The adsorption isotherm of alkanols at the haematite|hydrocarbon interface should reflect both chemisorption (chemically bonded fraction) and physisorption (hydrogen bonded fraction). EXPERIMENTS AND MODEL: Quartz crystal microbalance (QCM) and X-ray photoelectron spectroscopy (XPS) have been used for characterization of Fe FINDINGS: All data show simultaneous physisorption and chemisorption of the alcohol. The CPL analysis reveals variability of the surface chemistry from one sample to another - different fractions of surface sites have been determined for Fe
