The use of CyDTA in the amperometric determination of metal-ion mixtures was studied systematically. Because of the sluggishness of the nickel(II)-EDMA∼CyDTA substitution reaction, the nickel(II) ion in the EDMA solution could be masked completely in respect to the CyDTA. Therefore, even in the presence of an excess of nickel(II)ions, the copper(II), lead(II), cobalt(II), cadmium(II), and zinc(II) ions in the EDMA solution at about pH=6.50 could be determined accurately with CyDTA. In the amperometric titration of binary mixture of copper(II) and zinc(II), lead(II), cadmium(II), or cobalt(II) ions in the EDMA solution, titration curves with two sharp breaks could be obtained by following the change in the diffusion current due to the reduction of the copper(II)–EDMA complex. The first and second breaks correspond, respectively, to the equivalence point of zinc(II), lead(II), cadmium(II), or cobalt(II) and to that of copper(II).
