化学镀镍液中次磷酸钠的快速测定

Rapid Measurement of Sodium Hypophosphite in Electroless Nickel Plating Bath

从方便、快速、准确的要求出发 ,通过与经典容量分析方法比较 ,研究了能满足快速测定化学镀镍液中次磷酸钠浓度的方法。加入过量I- 3,以淀粉为指示剂 ,用硫代硫酸钠滴定过量的I- 3。

For the requirements of convenience, quick and accurate, a method to meet the rapid measuring of sodium hypophosphite in electroless nickel plating bath was studied by comparing with classic volumetric analysis methods.
