It was found that the graphitic carbon strongly adsorbs chloroauric acid (HAuCI,) and sodium aurocyanide (NaAu[CN],) with the production of high heats of adsorption at low surface coverages. As the graphitized carbon possesses only a very small amount of polar surface sites, the adsorption is ascrib
