NOVELTY - A method for recovering gold from a solution containing gold ions, involves (S1) carrying out mixed reaction with graphene oxide dispersion liquid and reducing agent, (S2) after washing the reaction solution of step (S1), dispersing the obtained product in a solvent to obtain a dispersion solution containing reduced graphene oxide, (S3) mixing the solution containing gold ions and the dispersion to obtain an initial reaction solution, and reacting under stirring so that the reduced graphene oxide in the dispersion can adsorb and reduce the gold ions, and (S4) after washing and drying the reaction solution obtained in step (S3), calcining at high temperature in an oxygen-containing atmosphere, obtaining elemental gold. USE - Method for recovering gold from solution containing gold ions of metal elements in electronic waste such as printed circuit board and central processing unit (all claimed). ADVANTAGE - The method has ultra-high adsorption capacity and selectivity for gold ions, is simple and convenient, and is favorable for large-scale application.
