NOVELTY - Rapid adsorption of heavy metal chromium ions in wastewater involves (1) dissolving graphene oxide in water, atomizing the solution with an ultrasonic atomizer, then passing through a tube furnace, collecting with (PTFE) filter, and drying to obtain a graphene microsphere adsorbent, and (2) adding a certain amount of the graphene microspheres prepared in the step (1) to a certain concentration of chromium-containing wastewater, reacting at room temperature and a certain pH for a certain period of time, and then centrifuging to test the chromium ions before and after the adsorption concentration to calculate the amount of adsorption. USE - Rapid adsorption of heavy metal chromium ions in wastewater. ADVANTAGE - The method is simple, efficient and reusable.
