Sodium sulfate and sodiumphosphite are tending to be accumulated gradually in the solution during electroless nickel plating, which affect the life of the plating solution.
随着施镀的进行,化学镀镍液中的硫酸钠和亚磷酸钠的积累越来越多,从而影响镀液的使用寿命。

Under optimal conditions, the removing rates of phosphite radicals, sulfate radicals and sodium ions can reach 50%, 30% and 80% respectively. The mechanism is also discussed.
