Abstract

Abstract In this study, a electrochemical-chemical combined dissolution technology was conducted by electro-generated chlorine toobtain ruthenium solution from ruthenium metal. To find out the optimum leaching conditions of ruthenium in chloride solution,this leaching process was carried out on the variation of pH, reaction time, temperature and applied voltage at the electro-gen-erated chlorine system in the reaction bath. Also, ozone generator was used to obtain ruthenium(III) chloride solution to increase * Received : October 21, 2013·Revised : November 15, 2013·Accepted : December 5, 2013Corresponding Author : Jong-Gwan Ahn (E-mail : dran@jwu.ac.kr)Department of Resources Recycling and Environmental Engineering, Jungwon University, 85, Munmu-ro, Goesan-eup, Goesan-gun, Chungbuk, 367-805, KoreaTel : +82-43-830-8627 / Fax : +82-43-830-8115 ⓒThe Korean Institute of Resources Recycling.
