In this paper, a theoretical formula for the analysis of chronopotentiometry on gold electrode is derived, and the application conditions of the simplified formula are discussed. When τ / l ~ 2≥3.0 × 10 ~ (11) S · cm_ (-2), a simplified transition time equation can be used: (?) If t≥2s, τ≥20s, then when l≤5.0 × 10 ~ (-6) cm, can be simplified using the potential - time equation: (?) After verification, the experimental results consistent with the theory.
