Abstract
A method of extracting platinum group metals from waste catalysts through an electrochemical process is disclosed. The extracting method includes positioning the waste catalysts between both electrodes in an electrolytic cell, leaching the platinum group metals as regularly changing polarities of the electrodes to each other, and precipitating the platinum group metals on a cathode by circulating the electrolyte from an anode to a cathode. According to the method, the platinum group metals can be extracted with high efficiency and high yield. Also, the extracting process is simplified to remarkably reduce costs required to extract the platinum group metals.
