NOVELTY - Preparation of magnetic graphene oxide, involves: adding ferric acetylacetonate and the graphene oxide in octylamine and octanol mix solution in ratio of 0.1-5 g:1 g:5-100 ml:10-200 ml, respectively; ultrasonically dispersing in reaction vessel for 10-300 minutes at a frequency of 40 KHz; performing high temperature reaction at 200-300 degrees C for 1-3 hours; cooling to room temperature; separating magnetic substance using magnetic separation; repeatedly washing with organic solvent, and then drying separated magnetic substance at 60-110 degrees C for 1-5 hours to obtain magnetic graphene oxide. USE - For preparation of magnetic graphene oxide (claimed) useful in waste water treatment. ADVANTAGE - The magnetic graphene oxide prepared by this method provides superparamagnetic and strong adsorption performance; can be used in waste water treatment; has good magnetic properties and adsorption capacity, and stable physical and chemical properties; and has low cost, and rapid separation and recovery characteristics. DETAILED DESCRIPTION - Preparation of magnetic graphene oxide, involves: adding ferric acetylacetonate and the graphene oxide in octylamine and octanol mix solution, where the ferric acetylacetonate, graphene oxide, octylamine and octanol are present in a ratio of 0.1-5 g:1 g:5-100 ml:10-200 ml; transferring the mixture to reaction vessel; ultrasonically dispersing for 10-300 minutes at a frequency of 40 KHz; performing a high temperature reaction at 200-300 degrees C for 1-3 hours; after completion of the reaction cooling to room temperature; separating the magnetic substance using magnetic separation; repeatedly washing with organic solvent, and then drying the separated magnetic substance at 60-110 degrees C for 1-5 hours; and finally obtaining the magnetic graphene oxide.
