摘要：

The anodic stripping voltammetry of hexavalent molybdate was investigated with a hanging mercury drop electrode in phosphate-borate buffer solution of pH 5.8-6.7. It was found that the deposition reaction was limited by the diffusion of the protonated molybdate ion, and the anodic stripping reaction was kinetically controlled by the dissolution of the deposited molybdate. A calibration curve for the anodic peak current versus Mo(VI) concentration was linear when Mo(VI) was within the range of 7×10-6 M and 2×10-4 M at pH 5.80. Various effects for the calibration curve were studied, and its application for the determination of Mo(VI) was discussed. © 1979 Elsevier Sequoia S.A.
