Incorporation of Trace Elements into Calcite Precipitated from Deep Anoxic Groundwater in Fractured Granitoid Rocks

Interaction of arsenic and carbonate mineral in groundwater system: Effect of oxidation state on arsenic incorporation into calcite

skopos theory and translating strategies of csis in translaed literary texts from english into persian

abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...

Incorporation of Eu(III) into Calcite under Recrystallization conditions

The interaction of calcite with trivalent europium under recrystallization conditions was studied on the molecular level using site-selective time-resolved laser fluorescence spectroscopy (TRLFS). We conducted batch studies with a reaction time from seven days up to three years with three calcite powders, which differed in their specific surface area, recrystallization rates and impurities cont...

Interactions between trace elements and dissolved organic matter in the stagnant anoxic deep layer of a meromictic lake

About 80% and more than 90% of the dissolved organic carbon (DOC) in the bottom water of Lake Pavin were isolated, respectively, on Amberlite XAD and Spherodex DEAE resins. Trace element concentrations in the fractions isolated were analyzed by using ICP-MS. Uranium, molybdenum, and antimony were found to be about 40% associated with fulvic and hydrophilic acids adsorbed on XAD resins at pH 2, ...
