Determination of Nickel concentration in Pd-Ni plating bath
Nickel analysis makes it possible to quantify the concentration of Nickel in Pd-Ni plating baths, within which this metal serves as the primary brightener. If the amount of Ni in the plating bath is lower than expected, the plating process may be suboptimal, leading to problems with aesthetic defects (e.g. glazing) in finished products. For this reason, monitoring the concentration of Ni in Pd-Ni baths is critical to ensure the good performance of plating processes.
Method
Test type: End Point.
Time testing: 3 minutes
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR GalvanLab®.
Sample treatment
The analysis does not require any pretreatment of the sample, which can be used as is.
Test principle
Nickel content is determined by its reaction with a chromogen that develops a coloration, the optical intensity of which is proportional to the Ni concentration in the sample analyzed.
Calibration curve
The calibration curve was obtained by correlating the CDR method with the reference method.
