Abstract

This study employs a low-field NMR (LF-NMR) method to investigate Cr(VI) adsorption and reduction in solid-liquid systems, focusing on three cellulose-based amine adsorbents. NMR revealed the effects of molecular structure on adsorption and reduction processes, providing insights into adsorbent design and mass transfer advantages for high-performance Cr(VI) adsorbents.
