WebApr 6, 2024 · The response of the gel surface to the increase in pH is much faster than the bulk response (Figure 5C), likely because there is no diffusion limitation to the surface. Reverse-phase contact angle measurements were conducted by placing a drop of dimethyl carbonate on the gel while immersed in an aqueous solution (Figure 5C). The reverse … WebA surface complexation model for the chemical structure and reactivity of the carbonatewater interface is presented. The model postulates the formation of the hydration species >CO3H0 and >MeOH0 at the surface of a divalent metal carbonate MeCO3 (Me = Ca, Mn, Fe, etc.). The existence of these primary hydration species is supported by …
WebAug 1, 2009 · Two different types of uranyl polymers have been considered, with and without carbonate. We have assumed that the polymers are bound to the surface via edge binding of a uranyl moiety, i.e. the surface charge contribution has been fixed at Δz 0 = 0.9 v.u. In solution, di- and tri-uranyl polymers can be found (see Table A1 in the Appendix).
