✦ Synopsis
The modified equation of the Frumkin-Fouler-Guggenheim isotherm was used to simulate the experimental data (, relative adsorption):
The model parameters were log B
H ؍ ؊4.92 ؎ 0.1, log B OH ؍ ؊2.61 ؎ 0.05, N ؍ 3.25 ؎ 0.2. The site density of the hematite surface was determined to be 3.8 ؎ 0.1 moles/m 2 . The values of the constants were log K HCl o (25-100°C) ؍ 9.50 ؎ 0.1; log K NaOH o (25-100°C) ؍ 5.93 ؎ 0.1.
