Abstract: Atheory 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 4.6×10-4cm. The effect of noise on the sensitivity Of RDCCSAis also discussed in some detail.

Key words: Constant-current stripping analysis, Reciprocal derivative, Spheric mercury film electrode
