▎ 摘　　要

NOVELTY - Producing pseudo graphene oxide magnetic adsorbent, comprises e.g. (a) gradually heating disaccharide sugar under nitrogen atmosphere in an electric furnace, rapidly increasing temperature, and maintaining temperature to produce pseudo graphene through thermal decomposition, (b) dispersing the pseudo graphene in distilled water, and performing ozone oxidation treatment with ozone generator, and (c) adding iron(II)/iron(III) mixed solution as ferromagnetic substance to the distilled water in which the pseudo graphene oxide is dispersed to perform magnetic separation under nitrogen atmosphere. USE - The pseudo graphene oxide magnetic adsorbent is useful for adsorbing and removing radioactive substances i.e. uranium and thorium contained in ground water, and in various water treatments. ADVANTAGE - The method is simple, economical and environmentally friendly, does not require chemicals in oxidation process, and can produce pseudo graphene oxide magnetic adsorbent in large-scale. The pseudo graphene oxide magnetic adsorbent can be magnetically separated in water, and quickly removes contaminants in water. DETAILED DESCRIPTION - Producing pseudo graphene oxide magnetic adsorbent, comprises (a) gradually heating disaccharide sugar from room temperature to 200 degrees C under nitrogen atmosphere for 1 hour in an electric furnace, maintaining temperature of 200 degrees C for 1 hour, rapidly increasing temperature from 200 degrees C to 750 degrees C for 1 hour, and maintaining at 750 degrees C for 3 hours to produce pseudo graphene through thermal decomposition, (b) dispersing the pseudo graphene in distilled water, and performing ozone oxidation treatment with ozone generator for 25-30 minutes to produce pseudo graphene oxide, and (c) adding iron(II)/iron(III) mixed solution as ferromagnetic substance to the distilled water in which the pseudo graphene oxide is dispersed to perform magnetic separation under nitrogen atmosphere, adjusting pH to 10-12 with ammonia solution, and stirring at 75-85 degrees C to produce pseudo graphene oxide magnetic material.
