NOVELTY - Preparing magnetic polypyrrole/graphene oxide composite material comprises (i) in situ polymerizing pyrrole monomer and graphene oxide, (ii) modifying polypyrrole/graphene-based composites using magnetic iron, and (iii) adding 30 wt.% aqueous ammonia solution, stirring for 1-3 hours, and then magnetically separating the magnetic polypyrrole/graphene oxide composite in the magnetic separation solution, washed and drying. USE - The method is useful for preparing magnetic polypyrrole/graphene oxide composite material (claimed). ADVANTAGE - The method: is simple; has mild experiment condition; is economical and low energy consumption, the multiple heavy metal ions and organic contamination absorbing quantity, high treatment efficacy of waste water, finally, magnetic separating and recycling is simple and convenient without secondary pollution, high analyzing the adsorption repeating utilization efficacy; and has a magnetic separation property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use magnetic polypyrrole/graphene oxide composite material in waste water treatment comprises adjusting pH value of waste water to 3-10, adding the magnetic polypyrrole/graphene oxide composite material, oscillating for 1-4 hours at normal temperature, and then applying external magnetic field, separating the external magnetic field from the solution after adsorption material is magnetizing to obtain the purified waste water.
