Figure 2From: Sorption of phosphate onto mesoporous γ-alumina studied with in-situ ATR-FTIR spectroscopyInfrared spectra showing phosphate adsorbed on mesoporous γ -alumina from a 0.050 mM aqueous phosphate solution at pH: 4.05, 4.96, 6.16, 6.97, and 9.0. The absorption intensity decreased with increasing pH.Back to article page
