An aqueous acid baths of rhodium and compositions of these baths containing rhodium

摘要

P baths of electrolytic deposition of rhodium and composition containing them. / p & & p & these aqueous baths acids of the coating of rhodium comprise 0,1 to 30 g / l of rhodium, 0,1 to 20 g / l of a polycarboxylic organic carboxylic acid containing at least one amino group, and 10 to 100 g / l of radicals orthophosphates, the bath having a ph of 0,1 to 2,0. / p & & p & the present invention is particularly useful for supplying coating baths of rhodium, where the content of rhodium is maintained at a low value, while providing an electrolytic deposit a brilliant. / p
