Figure 6From: Sorption of phosphate onto mesoporous γ-alumina studied with in-situ ATR-FTIR spectroscopyAdsorption isotherms of phosphate at pH 4.1 (A) and 9.0 (B) upon adsorption at the water-mesoporous γ -alumina interface. The solid and dotted lines are the results of fitting using the Freundlich and the Langmuir models, respectively. IA denotes Integrated Absorbance.Back to article page
