0.1 or 0.01 mol/L KNO3; Total site density (1.38 sites/nm²) is the summation of 0.69 nm-2 singly-coordinated ≡AlOH sites and 0.69 nm-2 singly-coordinated ≡SiOH sites, which assumes one aluminol and one silanol per 1.45 nm² of edge surface (Sposito, 1984; Tertre et al., 2006). Site density values were computed using: nS = (STAN)/(1018aSA) , where AN is the Avogadro constant; C2 = 0.2 F/m² was taken from [SS97] |
