摘要
Conditions for the formation of a stable and reproducible thin-film mercury microdrop cover on electrodes from carbon glass ceramics, carbon glass, and graphite are proposed. The influence of various factors on the parameters of signals from cadmium (II), lead (II), and copper (II) is studied by stripping voltammetry with linear, differential-pulse, sinusoidal, and square-wave potential sweep. The parameters of the stripping voltammetric experiment are optimized. The value of RSD in determining the specified modeling trace components did not exceed 15%. Approaches to the multicomponent stripping voltammetric analysis of waters are proposed.
