<p>An electrolytic compsn. for extg. impurities in iron and steel material is prepd. by adding citric acid below 20 wt.% to aq. electrolytic soln. of iron chloride 8-15 wt.%. An electrolytic apparatus consists of acrylic bath (1), circulation pump (7), anodes (2,5) of specimens, cathodes (3,6) for plating iron ions (from the anode), and porous net (4) for collecting nonelectrolytic matters.</p> |
