“…The raster scanning technique used in AFM can also lead to distortion of dynamic features (such as dissolving etch pits) due to the temporal nature of AFM data acquisition. A correction for the temporal nature of AFM image acquisition is given by Hillner et al 4 but was not used in the data presented here.…”

“…Calcite, CaCO 3 , growth and dissolution mechanisms in supersaturated and undersaturated solutions, respectively, have been elucidated on the atomic-scale using the AFM. [2][3][4][5][6][7] AFM analysis of crystal growth in the presence of inhibitors such as 1-hydroxyethylidene-1,1-diphosphonic acid(HEDPor etidronic acid) has also been reported. 8,9 The morphology of surface features on the (1014) cleavage plane of calcite is generally rhombic.…”

“…8,9 The morphology of surface features on the (1014) cleavage plane of calcite is generally rhombic. [2][3][4]6,[8][9][10] Both positive surface features (terraces and hillocks) and negative surface features (pits) display this rhombic morphology. Furthermore, the orientation of all the rhombic features on the (1014) cleavage plane is the same, with the short and long diagonals of the rhomboid running parallel to the [221] and [010] crystal indices, respectively as shown in Figure 1.…”

Morphology changes in etch pits formed on the (1014) cleavage plane of calcite were induced by varying the ratio of [Ca 2+ ] to [CO 3 2− ] in the bulk solution as well as through the addition of the crystal poison 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP). Three distinct morphologies were noted: symmetric rhombic, asymmetric rhombic, and triangular with a rough curved hypotenuse. The latter represents a transient morphology which is only observed during the actual dissolution process, while the former morphologies persist after dissolution is halted.

“…Atomic-force microscopy (AFM) has emerged as a technique for direct, nanometer-scale imaging of mineral surfaces immersed in aqueous solution (Binnig et al 1986, Johnsson et al 1991, Hillner et al 1992a, 1992b, Gratz et al 1993, Dove and Hochella 1993, Ohnesorge and Binnig 1993 and of particulate mineral surfaces in air (Hartman et al 1990, Lindgreen et al 1991, Blum and Eberl 1992. In this paper, we describe experiments wherein AFM was utilized to: (1) image in situ the basal-plane surface microtopography of single-crystal hematite over the course of reaction with a citric-acid solution; and (2) image ex situ at nanometer-scale resolution the surfaces of hematite particles following their reaction with oxalic-acid solutions for time periods ranging from 2 to >60 hours.…”

Abstract--The surface microtopography of hematite over the course of dissolution in oxalic and citric acids was examined by in-situ and ex-situ atomic-force microscopy, ln-situ imaging of the basal-plane surface of a centimeter-scale natural hematite sample immersed in 2 mM citric acid demonstrated that the basal-plane surface was relatively unreactive; rather, dissolution occurred along step edges and via etch-pit formation. Ex-situ imaging of synthetic hematite particles following batch dissolution in 1 mM oxalic acid showed similar dissolution features on basal-plane surfaces; in addition, etching along particle edges was apparent. The presence of etch features is consistent with a surface-controlled dissolution reaction. The results are in agreement with previous investigations suggesting that the basal-plane surface is relatively unreactive with respect to ligand exchange. Both in-situ and ex-situ imaging of particle surfaces can provide valuable information on the roles of surface structures and microtopographic features in mineral dissolution.

“…Indeed, as presented in Section 1.3.1.1, a difference of up to 20% is introduced if we consider the Pitzer database as the reference (see Appendix). This variability can also be due to the interaction of calcite with solute species: Martin-Garin et al (2003) evidenced that cadmium impacts the reactivity of the calcite crystal surface, as showed in previous studies (Dove and Hochella, 1993;Fenter et al, 2000;Hillner et al, 1992;Reeder, 1996). Also, some experiments present a Ca(II) concentration higher than the maximum value of the calibration range, which can lead to a drift in the measured value.…”

-The sorption of inorganic elements on carbonate minerals is well known in strictly controlled conditions which limit the impact of other phenomena such as dissolution and/or precipitation. In this study, we evidence the behavior of Zn(II) (initially in solution) and two trace elements, Mn(II) and Sr(II) (released by carbonate dissolution) in the context of a leakage from a CO 2 storage site. The initial pH chosen are either equal to the pH of the water-CO 2 equilibrium (~2.98) or equal to the pH of the water-CO 2 -calcite system (~4.8) in CO 2 storage conditions. From this initial influx of liquid, saturated or not with respect to calcite, the batch experiments evolve freely to their equilibrium, as it would occur in a natural context after a perturbation. The batch experiments are carried out on two natural carbonates (from Lavoux and St-Emilion) with P CO 2 = 10 À3.5 bar, with different initial conditions ([Zn(II)] i from 10 À4 to 10 À6 M, either with pure water or 100 g/L NaCl brine). The equilibrium regarding calcite dissolution is confirmed in all experiments, while the zinc sorption evidenced does not always correspond to the two-step mechanism described in the literature. A preferential sorption of about 10% of the concentration is evidenced for Mn(II) in aqueous experiments, while Sr(II) is more sorbed in saline conditions. This study also shows that this preferential sorption, depending on the salinity, is independent of the natural carbonate considered. Then, the simulations carried out with PHREEQC show that experiments and simulations match well concerning the equilibrium of dissolution and the sole zinc sorption, with log K Zn(II)~2 in pure water and close to 4 in high salinity conditions. When the simulations were possible, the log K values for Mn(II) and Sr(II) were much different from those in the literature obtained by sorption in controlled conditions. It is shown that a new conceptual model regarding multiple Trace Elements (TE) sorption is required, to enable us to better understand the fate of contaminants in natural systems.
