Determination of Total Nickel Concentration in Ni electroplating baths

Nickel is used in chemical nickel plating processes, where a galvanic treatment that allows different types of materials (iron, copper, brass, steel, zamak) to be coated with two prevailing purposes: nickel plating for decorative purposes and for technical-functional purposes. One feature of the nickel plating bath is that by changing the electrolyte composition and operating conditions, the properties and appearance of the nickel plated product can be customized to meet specific requirements. Generally, a typical nickel plating bath contains two Nickel salts: Nickel Sulfate, which is the main source of Nickel ions, and Nickel Chloride, which is essential for proper anodic corrosion and optimum bath conductivity. The total Nickel value is given by the total Ni ions (from Nickel Sulfate and Nickel Chloride) and is significant for preventing nodular or burned deposits.
