▎ 摘　　要

NOVELTY - Preparing magnesium hydrate/graphene oxide composite absorbing material for treating phosphorus-containing wastewater, comprises chemical oxidation of natural graphite, adding magnesium chloride solution into graphene oxide solution under stirring for 1-3 hours, filtering, washing and drying mixture to obtain the magnesium hydrate/graphene oxide composite material, adding obtained magnesium hydrate/graphene oxide composite material in water for 1-2 hours, adding reducing agent, and performing reduction reaction of 800 watts microwave for 2-5 minutes and then filtering, washing and drying. USE - The method is useful for preparing magnesium hydrate/graphene oxide composite absorbing material for treating phosphorus-containing wastewater (claimed). ADVANTAGE - The method produces magnesium hydrate/graphene oxide composite absorbing material with excellent adsorption capacity.
