▎ 摘 要
NOVELTY - Preparing modified graphene oxide solid adsorbent involves reacting the amino ionic liquid and graphene oxide followed by ring-opening reaction to obtain modified graphene oxide solid adsorbent. USE - Method for preparing modified graphene oxide solid adsorbent for adsorbing sulfur dioxide. ADVANTAGE - The method enables to prepare modified graphene oxide solid adsorbent for adsorbing sulfur dioxide has higher absorption efficiency and good stability that can be used repeatedly, and improves by 31%, and has fast desorption.
