Abstract: An experimental implementation of elimination polarography based on a previously developed theory is described. For the linear combination of instantaneous Polarographie current, its time integral and time derivative, and tasting the resulting function, a DC polarograph adapter was built. The results of capacity current elimination at a micromolar concentration of depolarizers confirm the theory and justify the conclusion that the sensitivity limit is comparable to pulse methods. Moreover, a new effect of current depression before Zn(II) reduction in this concentration range is observed.
