在ｐＨ４．４的ＨＣＯＯＨ－ＨＣＯＯＮａＡ介质中，钼（ＶＩ）与高铁试剂（Ｆｅｒｒｏｎ）生成络合物，在ＣＴＭＡＢ存在下，于－０．４８Ｖ（ｖｓ．ＳＣＥ）出现一尖锐、灵敏的极谱波。钼含量在４．２×１０－８～５．７×１０－６ｍｏｌ／Ｌ范围内与峰高呈线性关系。用多种电化学方法研究了极谱波的性质及电极反应机理，证明络合波为吸附波。峰电流由中心离子Ｍｏ（ＶＩ）还原产生。络合物组成为Ｍｏ（ＶＩ）：Ｆｅｒｒｏｎ＝１：１。试验了三十多种离子对峰电流的影响。方法用于自来水中钼的测定，结果满意。
In the HCOOH-HCOONaA medium at pH 4.4, molybdenum (VI) forms a complex with the ferron, giving a sharp, sensitive polarographic wave at -0.48 V (vs.SCE) in the presence of CTMAB . The molybdenum content in the range of 4.2 × 10-8 ~ 5.7 × 10-6mol / L showed a linear relationship with the peak height. A variety of electrochemical methods were used to study the nature of the polarographic wave and the electrode reaction mechanism. It was shown that the complexation wave was an adsorptive wave. The peak current is generated by the reduction of the central ion Mo (VI). The complex composition is Mo (VI): Ferron = 1: 1. The effect of more than thirty ions on the peak current was tested. The method was applied to the determination of molybdenum in tap water with satisfactory results.
