▎ 摘 要
NOVELTY - Preparing graphene resin comprises mixing graphite oxide dispersion with sodium hydroxide, then adding bromoacetic acid and reacting to obtain carboxylated graphene, and mixing resin monomer and the carboxylated graphene and reacting to obtain final product. USE - The graphene resin is useful as rhenium adsorbent in adsorption of trace rhenium (claimed). ADVANTAGE - The graphene resin: contains large amount of carboxy groups and small amount of hydroxy groups, and resin itself contains strong basic exchange group, which improves the adsorption performance of the resin; has better adsorption effect, and high adsorption rate of greater than or equal to 99%; and is economical.
