“…Moreover, dominant surface species are in agreement with the recently published surface complexes derived from XAS data for Cd, Cu, and Pb (Spadini et al, 1994;Ostergren et al, 2000;Scheinost et al, 2001). However, some data sets are clearly not well described by the model in the case of goethite (data set of Johnson (1990) with Cd = 0.2 mmol L À1 or data set of Kooner (1993) with I = 0.01 mol L À1 , results not shown here) or HFO (e.g., Fig. 4e).…”

“…In the absence of an organic ligand, Pb is known to adsorb strongly to goethite with increasing pH (Hayes and Leckie, 1986;Roe et al, 1991;Müller and Sigg, 1992;Kooner, 1993;Rodda et al, 1993;Gunneriusson et al, 1994). Figure 2 (square symbols) indicates that pH 50 Ϸ 5.5 and, at pH Ͼ 7, all Pb added is adsorbed.…”

Abstract-Hydroxamate siderophores are biologically-synthesized, Fe(III)-specific ligands which are common in soil environments. In this paper, we report an investigation of their adsorption by the iron oxyhydroxide, goethite; their influence on goethite dissolution kinetics; and their ability to affect Pb(II) adsorption by the goethite surface. The siderophores used were desferrioxamine B (DFO-B), a fungal siderophore, and desferrioxamine D 1 , an acetyl derivative of DFO-B (DFO-D1). Siderophore adsorption isotherms yielded maximum surface concentrations of 1.5 (DFO-B) or 3.5 (DFO-D1) mol/g at pH 6.6, whereas adsorption envelopes showed either cation-like (DFO-B) or ligand-like (DFO-D1) behavior. Above pH 8, the adsorbed concentrations of both siderophores were similar. The dissolution rate of goethite in the presence of 240 M DFO-B or DFO-D1 was 0.02 or 0.17 mol/g hr, respectively. Comparison of these results with related literature data on the reactions between goethite and acetohydroxamic acid, a monohydroxamate ligand, suggested that the three hydroxamate groups in DFO-D1 coordinate to Fe(III) surface sites relatively independently. The results also demonstrated a significant depleting effect of 240 M DFO-B or DFO-D1 on Pb(II) adsorption by goethite at pH Ͼ 6.5, but there was no effect of adsorbed Pb(II) on the goethite dissolution rate.

“…In other sites in the area copper-rich precipitates were observed in water with pH around 7 (Dinelli et al, 1998;Dinelli & Tateo, 2002). The mine area, as well as the Santa Barbara Adit, actually has a pH close to 6, which could also cause an increase in copper adsorption onto goethite with or without the presence of organic substances, as testified by several authors (e.g., Kooner, 1993;Christophi & Axe, 2000;Buerge-Weirich et al, 2002;Ponthieu et al, 2006).…”

Abstract:The aim of this study is to characterize in detail, the mineralogy of different-shaped concretions as well as to investigate the physico-chemical parameters of the associated mine drainage and drip waters in the Santa Barbara level of the Libiola Mine (NW Italy) by several geochemical and mineralogical techniques. Under the term "minothems" we are grouping all those secondary minerals that occur under certain form or shape related to the conditions under which they formed but occur in a mine, or in any artificial underground environment (i.e., "mine speleothems"). Different types of minothems (soda straw stalactites, stalactites, and draperies) were sampled and analyzed. Mineralogical results showed that all the samples of stalactites, stalagmite and draperies are characterized by poorly crystalline goethite. There are significant differences either in their texture and chemistry. Stalactites are enriched in Zn, Cd, and Co in respect to other minothems and show botryoidal textures; some of these exhibit a concentric layering marked by the alternation of botryoidal and fibrous-radiating textures; the draperies are enriched in V and show aggregates of sub-spheroidal goethite forming compact mosaic textures. Geochemical investigations show that the composition and physico-chemical parameters of mine drainage and drip waters are different from the other acidic mine water occurrences in different areas of the Libiola Mine, where minothems are less abundant. All mine water samples contain Cu, Ni, and Zn in appreciable levels, and the physico-chemical conditions are consistent with the stability of ferrihydrite, which however tends to transform into goethite upon ageing.
