在 pH～2的0.1M 氯亿锂溶液中,钼-10—十一碳烯氧肟酸配合物产生两个明晰的阴极化示波极谱波,峰电位分别为-0.34V 和-0.63V(vs.SCE),后者灵敏度较高,其二次导数波峰电流与钼浓度在1.0×10~(-8)～1.0×10~(-2)M 范围内有良好的线性关系。文中提出了简单、准确的分析方法,讨论了配合物的性质,板谱反应机理及电极过程,认为获得的极谱波为吸附波,电极反应半可逆. In the 0.1M LiCl solution at pH ~ 2, the molybdenum-10-undecenoic acid hydroxamic acid complex produced two clear cathodic oscillopolarographic polar waves with peak potentials of -0.34V and -0.63V (vs.SCE). The latter is more sensitive and the second derivative peak current has a good linear relationship with molybdenum concentration in the range of 1.0 × 10 -8 to 1.0 × 10 -2 M. In this paper, a simple and accurate analytical method is proposed. The properties of the complex, the reaction mechanism of the plate spectrum and the electrode process are discussed. The obtained polarographic wave is the adsorptive wave and the electrode reaction is semi-reversible.
