摘　　要：介绍了磷钼酸喹啉重量法在化学镀镍磷镀层磷含量测定中的应用，并与GB／T13913—92分光光度法和X射线能谱（EDS）法进行了比较。结果表明，本方法测定相对误差为-1．65％～4．21％，能准确测定镍磷镀层磷含量；与EDS法对Ni—P镀层的对比测定表明，EDS法所测结果比重量法普遍偏高。The application of quinoline phosphomolybdate gravimetric method in the determination of phosphorus content in electroless Ni-P coating was introduced.The relevant measurement results were compared with that determined by national standard spectrophotometric method GB/T 13913-92 and energy dispersive spectroscopic(EDS) method as well.It was found that the relative error for the determination of P in electroless Ni-P coating using the titled method was within-1.65%~4.21%,indicating that the method could be well used to determine the phosphorus content in the electroless Ni-P coating.Moreover,the corresponding EDS measurement result for the same electroless Ni-P coating was relatively larger as compared with the result determined using the titled method.
