New insights into Mn<sup>2+</sup> and Mg<sup>2+</sup> inhibition of calcite growth
2022, Geochimica et Cosmochimica ActaCitation Excerpt :In particular, various forms of mineral carbonation, including in-situ mineralization of basalts or peridotites (Kelemen et al., 2011; Clark et al., 2020), ambient surficial weathering (Renforth et al., 2009; Beerling et al., 2020; McQueen et al., 2020), and engineered ex-situ mineralization of alkaline waste materials (Gerdemann et al., 2007), are increasingly attractive options for permanent storage of CO2 (Kelemen et al., 2020). Carbonate solid-solution formation is also a principal remediation technique for contaminants capable of being incorporated into the carbonate lattice (e.g. 90Sr - Lukashev, 1993; Achal et al., 2012). Geochemists have long sought to develop predictive models for the rate and composition of carbonate minerals growing from complex aqueous solutions typical of natural seawater, pore fluids, cave drip waters, wastewater, and other natural and engineered fluids.
Complexation of Eu(III), Pb(II), and U(VI) with a Paramecium glycoprotein: Microbial transformation of heavy elements in the aquatic environment
2018, ChemosphereCitation Excerpt :Examples of accidental discharge include the Chernobyl Nuclear Power Plant, Russia, in 1986, and the Fukushima Daiichi Nuclear Power Plant (FDNPP), Japan, in 2011. Large amounts of radionuclides, including Pu, have been released into surface water, groundwater, and seawater (Lukashev, 1993; Cook et al., 1997; Myasoedova and Drozhko, 1998; Dai et al., 2002; Bailly de Bois et al., 2012; Kanda, 2013; Oikawa et al., 2013; Keum et al., 2015). The FDNPP accident also severely contaminated sewage water (Shibata et al., 2012; Kamei-Ishikawa et al., 2013; Kozai et al., 2015).
Caoxite-hydroxyapatite composition as consolidating material for the chalk stone from Basarabi-Murfatlar churches ensemble
2015, Applied Surface ScienceCitation Excerpt :For the high concentration of Sr, we took into account the Chernobyl nuclear accident, too, knowing that 37.50 km2 were contaminated by radioactive material comprising Sr2+. Up to 70% of this metallic ion have been fixed in the ground after reaction with the solid carbonates, forming strontianite (CaxSr1−xCO3), which could nucleates on the calcite surface [38]. The difference in S content between calcite and vaterite increased with the initial SO42−:CO32− ratio ([SO42− inside] = 0.642%, [SO42− outside] = 0.370%).
General model for calcite growth kinetics in the presence of impurity ions
2013, Geochimica et Cosmochimica ActaCitation Excerpt :Impurity ions and ionic molecules are widely known to inhibit the growth and alter the composition of carbonate minerals precipitating from aqueous solution (Meyer, 1984; Burton and Walter, 1990; Cabrera and Vermilyea, 1958; Davis et al., 2000b; Reddy and Hoch, 2000; Wasylenki et al., 2005b,a; Lin and Singer, 2006). Use of trace element signatures for paleoclimate reconstruction, retardation of contaminant transport (Lukashev, 1993), and preventing pipe scaling requires an understanding of controls on the surface interaction and incorporation of impurities during carbonate mineral growth. Despite the widespread application of trace element signatures, the nonlinear effects of certain trace elements, such as strontium, on calcite precipitation rate have largely eluded explanation (Wasylenki et al., 2005b).
Radiocarbon of dissolved humic substances in river waters from the Chernobyl area
2004, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :The Chernobyl humic substances consist of old organic materials, but a large amount of 14C was released by the accident in 1986. The Sakhan and Pripyat River watersheds consist of peat, bog, and podzolic soil [22,23]. Soil humic substances are of greater 14C age (lower Δ14C), especially for peat and wetlands [4,24].
