Description
Fremgangsmåte ved rensning av metaller som er ut felt katalytisk fra metallsaltopplosninger, på formede gjenstander. Procedure for the purification of metals that have been catalytically precipitated from metal salt solutions, on shaped objects.
Foreliggende oppfinnelse angår en fremgangsmåte ved rensning av på en formet gjenstand katalytisk fra metallsaltopplosninger utfelte metallskikt (ikke katalysatorer), som er forurenset av i oppløsningen tilstedeværende for.utfeiningen nodvendige tilsetning-er. The present invention relates to a method for cleaning catalytically deposited metal layers (not catalysts) on a shaped object from metal salt solutions, which are contaminated by additives necessary for the refinement present in the solution.
Ved katalytisk utfelning av metall fra metallsaltopplosninger er mengden av forurensning en funksjon av pH-verdien av det an-vendte bad. Når det for eksempel er sporsmål om nikkel, hvorved der forekommer nikkelfosfider, kan de sistnevnte gå opptil 10 % ved en pH-verdi på <l>f,5. Hvis pH-verdien senkes til 3,5 oker fosfid-innholdet hurtig helt opp til V/%. In the case of catalytic precipitation of metal from metal salt solutions, the amount of contamination is a function of the pH value of the bath used. When there are, for example, traces of nickel, whereby nickel phosphides occur, the latter can go up to 10% at a pH value of <l>f.5. If the pH value is lowered to 3.5, the phosphide content quickly rises to V/%.
I IN
Hvis utfeiningen derimot skjer i et på det nærmeste noytralt \ eller alkalisk bad, minskes nikkelfosfidinnholdet meget betrakte- j lig, men istedet utfelles nikkelhydroxyder, i likhet med forholdet :ved galvaniske bad ved en pH-verdi over 5,5. Disse nikkelhydroxyder kan være av to forskjellige slag, nemlig på den ene side NKOH^j .som lett kan elimineres ved oppvarmning, og på den annen side j Ni„(K .X(H,-,0) som derimot ikke spaltes for ved 600°C. Allerede j ved i+00 C begynner spaltningen ved et visst tap av C>2, som oxyderejr opp det utfelte nikkel. If, on the other hand, the removal takes place in an almost neutral or alkaline bath, the nickel phosphide content is reduced very considerably, but instead nickel hydroxides are precipitated, similar to the situation in galvanic baths at a pH value above 5.5. These nickel hydroxides can be of two different types, namely on the one hand NKOH^j .which can be easily eliminated by heating, and on the other hand j Ni„(K .X(H,-,0)) which, on the other hand, is not decomposed by 600° C. Already at i+00 C, the cleavage begins with a certain loss of C>2, which oxidizes the precipitated nickel.
Det er tidligere kjent å redusere metallforbindelser til metall ved hjelp av en reduserende gass ved forhoyet temperatur, j Så er der, for eksempel i tysk patentskrift nr. 859.<1>+<1>+2, beskrevetj en fremgangsmåte for å fremstille en katalysatormasse ved reduk-sjon med en reduserende gasstrom, og hydrogen er spesielt nevnt som i reduserende gass. Ved foreliggende fremgangsmåte kan man, uten fare for ujevnheter i skiktet, fjerne eventuelle forurensninger i skikti ; avsatt på slike gjenstander som glassplater og tråd, hvilket skil-! ler seg helt fra de tidligere kjente fremgangsmåter. Foreliggende j fremgangsmåte angår ikke fremstilling av katalysatorer. It is previously known to reduce metal compounds to metal by means of a reducing gas at an elevated temperature, j Then there is, for example, in German patent document no. 859.<1>+<1>+2, describedj a method for producing a catalyst mass by reduction with a reducing gas stream, and hydrogen is specifically mentioned as in reducing gas. With the present method, one can, without risk of unevenness in the layer, remove any contamination in the layer; deposited on such objects as glass plates and wire, which separate-! departs completely from the previously known methods. The present method does not relate to the production of catalysts.
De., ovenfor påpekte forhold angår ikke spesielt nikkel, men ! ekvivalente forhold råder også ved andre metaller med forurensninger av annet slag. ! The conditions pointed out above do not particularly concern nickel, but ! equivalent conditions also prevail for other metals with impurities of a different kind. !
Når man således katalytisk har utfelt et metall fra dets ; metallsaltopplosning på en passende bærer, som kan utgjores av en ! gjenstand efter valg, plate eller tråd av forskjellig slag, er metallskiktet ifolge ovenstående ikke kjemisk rent, men forurenset<i >i forskjellig grad. When one has thus catalytically precipitated a metal from its ; metal salt solution on a suitable carrier, which can be constituted by a ! object of choice, plate or wire of different kinds, according to the above, the metal layer is not chemically clean, but contaminated to varying degrees.
Hvis man velger nikkel som et eksempel på fremgangsmåtens ut-j forelse, er dette ikke begrensende efter som ekvivalente prosesseij :ifolge oppfinnelsen også kan gjennomfores med andre metaller med forurensninger. j If one chooses nickel as an example of the method's embodiment, this is not limiting since equivalent processes according to the invention can also be carried out with other metals with impurities. j

Den ved <i>fOO°C begynnende spaltning av nikkeloxydet Ni20^.X(H20) <;>forhindres ved hydrogenets reduserende virkning hvorved der dannes vann og fosforhydrid, som senere lett forflyktiges slik at rent metall blir tilbake i skiktet. The decomposition of the nickel oxide Ni20^.X(H20) <;> which begins at <i>fOO°C is prevented by the reducing action of the hydrogen, whereby water and phosphorous hydride are formed, which are later easily volatilized so that pure metal remains in the layer.
I visse forbindelser kan det ifolge oppfinnelsen være gunstig , i å gjennomfbre reduksjonen under et regulert trykk som kan være 1 over- eller undertrykk alt efter forholdene. In certain compounds, according to the invention, it can be beneficial to carry out the reduction under a regulated pressure which can be 1 over or under pressure depending on the conditions.
