球形汞膜电极倒导数恒电流溶出分析法研究

Studies on Reciprocal Derivative Constant-Current Stripping Analysis with a Spheric Mercury Film Electrode

本文推导并验证了球形汞膜电极倒导数恒电流溶出分析法理论。确定其理论的应用条件为汞膜厚度不超过4.6×10^(-4)cm,探讨了噪音对灵敏度的影响。

A theory of reciprocal derivative constan-current stripping analysis (RD-CCSA) with a spheric mercury film electrode(SMFE) is deduced and verified in this paper. The experimental resul sare in agreement with the theoretic ones. The condition of application for the theory is that the thickness of mercury film is not more than 4.6×10^(-4)cm. The effect of noise on the sensitivity Of RDCCSA is also discussed in some detail.
