摘要：
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.
