Abstract

PURPOSE: To easily recover a noble metal from an acidic soln. contg. noble metallic ions efficiently by passing hydrogen through the soln. in the presence of a reduction initiator generating nascent hydrogen in the soln.
CONSTITUTION: To an acidic soln. contg. noble metallic ions are added fine particles (black) of at least 1 kind of platinum group metal as a reduction initiator. By bubbling the black-added soln. with gaseous hydrogen, part of the hydrogen is activated by the catlytic effect and reacts with the black to generate nascent hydrogen. This nascent hydrogen reduces the noble metallic ions in the soln. and deposits black of the noble metal. The produced black is filtered easily and used as said reduction initiator most preferably. Iron or the like having higher ionization tendency than hydrogen and generating nascent hydrogen in the acidic soln. may be used as the reduction initiator.
