Description

Application

• 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).
