<p>PURPOSE: A method for recovering platinum from a platinum catalyst is provided to increase precipitation activity and prevent the emission of chlorine gas by adding acetone in a tetrakis(triphenylphosphine)platinum precipitation process. CONSTITUTION: A method for recovering platinum from a platinum catalyst comprises the steps of: adding aqua regia to a platinum-based catalyst to prepare chloroplatinic acid solution, filtering the chloroplatinic acid solution in order to separate insoluble solid components, adding acetone and triphenylphosphine to the filtrate in order to precipitate tetrakis(triphenylphosphine)platinum, and plasticizing tetrakis(triphenylphosphine)platinum precipitate in order recover platinum.</p> |
