Determination of Nickel Chloride concentration in Nickel plating baths
Nickel chloride plays a key role in nickel plating baths, a galvanic process used to coat various materials, including iron, copper, brass, steel and zamak, for both decorative and technical-functional purposes. The composition of the nickel plating bath can be modulated by varying the concentration of components and operating conditions, allowing specific coating characteristics to be obtained according to application requirements. Nickel chloride, in particular, is essential to ensure proper anodic dissolution and improve the conductivity of the bath. Monitoring and analysis of its concentration is critical to ensure uniform nickel deposition and avoid defects in the coating, such as burning or nodularity.
Method
Test type: End Point.
Time testing: 4 minutes
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR GalvanLab®.
Sample Treatment
The analysis is carried out on the nickel bath. Dilute the sample before the use.
Test Principle
Nickel Chloride content is determined, after dilution, by reaction with a chromogen. The test has a total duration of 4 minutes at the end of which a spectrophotometric reading is taken: the signal detected is directly correlated with the concentration of Nickel Chloride.
Calibration curve
Calibration curve was obtained by correlating the CDR method with the reference method.
Measuring range
| Analyses | Measuring range | Resolution | Repeatability |
