Surface complexation model for strontium sorption to amorphous silica and goethite
Geochemical Transactions, 2008 Strontium sorption to amorphous silica and goethite was measured as a function of pH and dissolved strontium and carbonate concentrations at 25°C. Strontium sorption gradually increases from 0 to 100% from pH 6 to 10 for both phases and requires multiple

Kinetics of conversion of celestite to strontium carbonate in solutions containing carbonate, bicarbonate and ammonium ions and dissolved ammonia [PDF]
Journal of the Serbian Chemical Society, 2014 Celestite concentrate (SrSO4) has been converted to SrCO3 in solutions containing CO32-, HCO3- and NH4+ ions and dissolved ammonia. The effects of stirring speed, CO32- ion concentration; temperature and particle size of SrSO4 on the reaction ...

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]
, 2001 The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Preparation of strontium hexaferrite magnets from celestite and blue dust by mechanochemical route [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2008 In the present investigation celestite (natural ore of strontium) and blue dust (iron ore fines) have been used for the preparation of strontium hexaferrite powder. The mechanical alloying process has been adopted to prepare strontium hexaferrite powder.

Effect of carbonate chemistry alteration on the early embryonic development of the pacific pyster (Crassostrea gigas) [PDF]
, 2011 Ocean acidification, due to anthropogenic CO(2) absorption by the ocean, may have profound impacts on marine biota. Calcareous organisms are expected to be particularly sensitive due to the decreasing availability of carbonate ions driven by decreasing ...

Annals of Microbiology, 2012 The physiological and global transcriptomic response of the metal-resistant bacterium Cupriavidus metallidurans CH34 to stable non-radioactive strontium (Sr) was investigated. C. metallidurans CH34 was able to survive and proliferate in the presence of relatively high concentrations of SrCl2 (concentration of Sr needed to inactivate 90 % of the cells =
