2. Maintenance and inspection
2.1 Influence of deposit control parameters
As a general rule, a decrease in pH leads to a lowering of cathodic efficiencies. The pH varies as a result of the cathodic and anodic reactions occurring during electrolysis, and excessive deviations can lead to the formation of hydroxides (see § ...

Regulations
At the time of writing, the use of nickel solutions and their release into the environment in surface treatment plants are subject to the regulations set out in the decree of September 26, 1985 (published in the Journal Officiel of November 16, 1985). This decree defines the maximum permissible concentration of various constituents, such as metal ions (chromium, copper, iron, zinc, cadmium, etc.) and other components (cyanides,...
