摘要：
Influences of a nonionic detergent Triton X-100 on square-wave voltammetry and anodic stripping square-wave voltammetry of Cd2+ in 0.5 M NaClO4 + 0.01 M HClO4 are measured at precisely controlled durations of adsorptive accumulation and surfactant concentrations. Diagnostic criteria for the presence of surface-active substances in electrolytes are reported. A voltammetric method for the quantitative analysis of detergents is proposed. An ionic type of detergent can be recognized by the variation of the accumulation potential.
