NOVELTY - Preparation of polyaniline nanorod/graphene/iron oxide absorbing material involves dispersing 3.0 g iron chloride-hexahydrate, 9 g sodium acetate into 150 ml graphite oxide/ethylene glycol solution, mechanically stirring, adding 30 ml ethylene diamine, transferring obtained mixture into autoclave lined with PTFE, oven heating at 200 degrees C for 8 hours, naturally cooling and alternately washing with water and ethanol, drying and grinding to obtain graphene/iron oxide composite material; and configuring 250 mL concentrated hydrochloric acid into 1 mol/L dilute hydrochloric acid concentration, dispersing 0.2 g iron oxide/RGO into 205 mL of 1 mol/L hydrochloric acid, mechanically stirring and adding 0.2 mL aniline to obtain mixture-A, dissolving 0.25 g ammonium persulfate into 5 mL of 1 mol/L hydrochloric acid to obtain mixture-B, dropping mixture-B into mixture-A under ice bath conditions at less than 5 degrees C for 24 hours, reacting, drying at 60 degrees C and grinding. USE - Method for preparing polyaniline nanorod/graphene/iron oxide absorbing material. DETAILED DESCRIPTION - Preparation of polyaniline nanorod/graphene/iron oxide absorbing material comprises dispersing 3.0 g iron chloride-hexahydrate, 9 g sodium acetate into 150 ml graphite oxide/ethylene glycol solution, mechanically stirring, adding 30 ml ethylene diamine, transferring obtained mixture into autoclave lined with polytetrafluoroethylene, oven heating at 200 degrees C for 8 hours, naturally cooling at room temperature, subjecting into suction filtration and alternately washing with water and ethanol, drying and grinding to obtain graphene/iron oxide composite material; and configuring 250 mL concentrated hydrochloric acid into 1 mol/L dilute hydrochloric acid concentration, dispersing 0.2 g iron oxide/RGO into 205 mL of 1 mol/L hydrochloric acid, mechanically stirring and adding 0.2 mL aniline to obtain mixture-A, dissolving 0.25 g ammonium persulfate into 5 mL of 1 mol/L hydrochloric acid to obtain mixture-B, mechanically stirring mixture-A for 30 minutes, dropping mixture-B into mixture-A under ice bath conditions at less than 5 degrees C for 24 hours, reacting, alternately washing with water and ethanol, drying at 60 degrees C and grinding.
