Addition of this reagent caused the difference in the halfwave potentials between the two ions to increase from 0.01 to 0.34 V. The relationship between the concentration of the ion and the wave current was linear for both ions, which suggests the feasibility of a simultaneous determination of Zn(II) and Ni(II) in the presence of a crown ether.
