Palladium or that alloy the electrolytic bath null palladium in order electrochemistry

摘要

(57) Abstract If as for this invention, palladium or of that alloy being water electrolysis bath of acidic pH in order to make precipitate electrochemistry, aforementioned bath, the palladium compound, and, is necessary, it includes the chemical compound of one which is precipitated second metal at least with also configuration of the alloy with the palladium, also ethylene diamine, and the organicity brightener as a palladium complexing agent furthermore include, the aforementioned brightener the 3- (the 3- pyridyl) the acrylic Acid, the 3- (the 3- quinolyl) the acrylic Acid or one of those salts, desirably the electrolysis which features that it is one of those alkaline metal saltsIt regards bath. Furthermore, being the manner which electricity plates the palladium or palladium alloy, using the current density 0.5 - 150A/dm2, it regards the manner which features that it makes the above-mentioned electrolysis bath work.
