NOVELTY - The method for efficiently removing metal copper ion adsorbent in waste water, involves adding natural graphite to concentrated sulfuric acid in ice bath, stirring, adding oxidant, heating the reaction, adding hydrogen peroxide, washing with dilute hydrochloric acid and deionized water, adding deionized water for ultrasonically processing, diluting with deionized water to form graphene oxide solution having concentration of 1-3 mg/ml mixing oil shale residue after acid leaching, alumina and sodium hydroxide heating in air, naturally cooling resulting solution, uniformly mixing obtained solution with graphene oxide aqueous solution and distilled water, ultrasonically treating for 1-3 hours, magnetically stirring to form uniform gel phase, transferring the gel phase to round bottom flask for condensing and refluxing, filtering obtained solid matter, washing and drying. USE - Method for efficiently removing metal copper ion adsorbent in waste water. ADVANTAGE - The method enables removal of metal copper ion adsorbent in waste water, and effectively adsorbs high doses of heavy metal copper ions from wastewater.
