Clean plating baths

Utilizing electrolytic recovery, customized resins, selective membranes, and adsorbents to separate metal impurities from plating baths, acid/caustic dips, and solvent cleaning operations. 

Silvei Silver Chloride Electrodes. Silver silver chloride electrodes may be made from thin sheet silver of high purity, but it is perhaps better to plate silver onto a clean square of platinum sheet or screen. This is made the cathode, and the anode is a strip of very pure sheet silver (at least 99.95 percent pure) in a plating bath containing 41 g silver cyanide, 40 g potassium cyanide, 11 g potassium hydroxide, and 62 g potassium carbonate... 

Use Production of fluoborates, electrolytic brightening of aluminum, throwing power aid in electrolytic plating baths, esterification catalyst, metal cleaning, making stabilized diazo salt. 

The plating baths used in the various applications of electrolysis often contain toxic materials or produce toxic by-products. After bath solutions have been used for a period of time, they must be changed and the toxic contents disposed of in a safe manner. Remarkably, electrolysis offers one of the safest and most thorough means of cleaning up toxic metal-containing wastes. When the bath solution is subjected to electrolysis, the toxic metal ions are reduced to free metal at the cathode. The metal can then be recycled or disposed of safely. 

Sections are floated on a clean water bath filled with distilled water at a temperature slightly below the melting point of the wax. After the sections spread out, subbed slides are placed beneath the floating ribbons to collect them and dried on a 37°C heating plate for 1 h, and then overnight in a 37°C oven. 

Avoid, where necessary, metals subject to hydrogen embrittlement from acid cleaning or plating, or use low hydrogen-producing plating baths. 

Because the plating process produces a clean, bondable surface, freshly plated surfaces often do not require additional preparation. Keep in mind, however, that plating changes surface properties such as adhesion, porosity, and surface stress of the metal deposit. Current density, composition of the plating bath (including brightener content), and bath temperature affect the bondabiUty of the plated surface.
