Aplicación


  • Separation of Gd-humic complexes and Gd-based magnetic resonance imaging contrast agent in river water with QAE-Sephadex A-25 for the fractionation analysis.: This study highlights the application of Tetramethylammonium sulfate in the separation of gadolinium complexes from river water using QAE-Sephadex A-25. The research demonstrates the effectiveness of this approach in environmental analytical chemistry, providing insights into the behavior and fate of contrast agents in natural water systems (Matsumiya et al., 2014).

Elucidating dissolution kinetics and mechanisms at carbonate mineral-water interfaces is essential to many environmental and geochemical processes, including geologic CO(2) sequestration in deep aquifers. In the present work, effects of background electrolytes on dolomite (CaMg(CO(3))(2)) reactivity were investigated by measuring
