Verfahren zur Herstellung eines Elektrolyten zum Niederschlagen von Metallen.
Es ist bekannt, dass durch Zusatz eines Reduktionsmittels zu galvanischen Bädern die Dissoziation der darin gelösten Metallsalze befördert, und die Niederschlagung des Metalles durch den Strom wesentlich erleichtert wird. Aus solchen stark dissoziierten Bädern können ohne
EMI1.1
von Zinn und Kupfer (Bronze), denen eine grosse wirtschaftliche und technische Bedeutung zukommt, niedergeschlagen werden.
Um einen beständigen Elektrolyten zu erhalten, ist es notwendig, dass als Reduktionsmittel eine Verbindung einer organischen Säure mit einer nicht flüchtigen Base angewendet wird. Da die galvanischen Bäder beim Ansetzen erwärmt werden, so muss überdies das Reduktionsmittel derart beschaffen sein, dass die Lösung nicht in nachteiliger Weise beeinflusst wird. Es wurde gefunden, dass unter den organischen Reduktionsmitteln das borzitronensaure M le. sium diesen Anforderungen entspricht und die günstigsten Ergebnisse liefert.
Zur Bereitung der galvanischen Bäder nach vorliegendem Verfahren wird die mit hor-

Das zur Verwendung gelangende Metallsalz muss im Elektrolyten vollständi iöstich sein und einen rein metallischen Niederschlag liefern. Im folgenden sind als Beispiel eirige Metallsalze angeführt, welche sich zur Bereitung derartiger Bäder eignen.

Process for producing an electrolyte for depositing metals.
It is known that the addition of a reducing agent to galvanic baths promotes the dissociation of the metal salts dissolved therein, and the deposition of the metal by the current is considerably facilitated. Such strongly dissociated baths can be used without
EMI1.1
of tin and copper (bronze), which are of great economic and technical importance.
In order to obtain a stable electrolyte, it is necessary that a compound of an organic acid with a non-volatile base is used as a reducing agent. Since the galvanic baths are heated during preparation, the reducing agent must also be of such a nature that the solution is not adversely affected. It has been found that among the organic reducing agents the boron citric acid M le. sium meets these requirements and delivers the most favorable results.
To prepare the galvanic baths according to the present process, the

to reduce and so cancel certain affinities, which does not occur at ordinary temperature. After cooling, the solution can be given a further amount of another reducing agent. by means of, e.g. B. glycocitric acid or glycovaric acid can be added to complete the dissociation.
The metal salt used must be completely dissolved in the electrolyte and produce a purely metallic deposit. In the following, iron metal salts are given as examples, which are suitable for preparing such baths.
For the crushing of gold, silver. Nickel or copper or from alloys of these metals the corresponding alkali double cyanides are used. Iridium is used as chloride,

which is formed when an alkaline tungstate solution is dropped into dilute nitric acid, dissolves in tartaric ammonium, which is mixed with potassium or sodium phosphate. To precipitate magnesium, a magnesium-mixed solution of dry magnesium sulfate in oxalic acid ammonium is used. A solution is used for aluminum
EMI1.4
the use of chromium sulphate, which is dissolved in potassium or aluminum sulphate, is recommended; in the case of molybdenum phosphomolybdic acid ammonium, which is dissolved in potassium hydroxide.
Galvanic baths for the precipitation of an alloy are prepared by either treating the solution of the metal salt mixture according to the method mentioned or treating the solutions of the individual metals separately and then mixing them together. Since the
