摘要：

To remove iodine, a novel chitosan/carbon dots-loaded nanocellulose/layered double hydroxide composite hydrogel (CCNL) was successfully synthesized to enable the simultaneous detection and removal of the iodide ion (I-). Adsorption experiments revealed that the CCNL exhibited an impressive maximum adsorption capacity of 231.9 mg/g at 25 degrees C. The adsorption isotherms closely conformed to the Langmuir model, and the adsorption kinetics followed the pseudo-second-order model. The CCNL demonstrated outstanding reusability, maintaining over 89.7 % of its initial adsorption capacity after six ...
