Abstract

PURPOSE: To considerably reduce treatment time by electrolyzing an aluminum material having undergone anodic oxidation treatment in specific conditions by using specific metallic salts thereby forming a selective absorption membrane.
CONSTITUTION: The concns. of metallic salts in an aqueous soln. which carries out electrolytic treatment are 50W200g/l, more preferably 80W130g/l Ni salt, 50W200g/l, more preferably 80W130g/l Co salt, 15W100g/l, more preferably 30W50g/l copper salt, 5W50g/l, more preferably 15W30g/l tin salt, and 60W 100g/l, more preferably 5W50g/l iron salt. The temps. of the aqueous metallic salt soln. are kept at 35W85°C, more preferably 40W60°C. Other elctrolysis conditions are approximately the same as those in the prior art, whereby, the treatment is completed in an extremely short time of about 0.5W5.0min.
