  • Controlling Electroless Nickel Baths Products Finishing

    Nickel concentration is determined by simple chemical analysis. A small sample of the solution is cooled to room temperature and analyzed with a standardized EDTA solution. The results can be expressed in percentage nickel activity. The optimum level for most EN systems is six g/liter nickel metal, which is equal to 100% activity.
