▎ 摘  要

NOVELTY - Preparation of graphene oxide/sodium alginate composite high-efficiency aerogel adsorbent comprises dispersing graphite oxide in water and ultrasonic stripping; adding sodium alginate and ultrasonic mixing; and placing in high-temperature and high-pressure hydrothermal reactor, reacting, repeatedly washing to neutrality, and freeze-drying. USE - The method is used for preparing graphene oxide/sodium alginate composite high-efficiency aerogel adsorbent for cationic dyes (claimed). ADVANTAGE - The aerogel absorbent has three-dimensional network structure, has more anionic adsorption sites which can adsorb better with cationic dyes, and uses anion and cation electrostatic adsorption.
