Determination of Trace Estrogens by the 1.5th Order Differential Stripping Analysis Using a Hanging Mercury Electrode

Abstract

Abstract: The present paper covers a new and sensitive method for the determination of trace estrogens,and the 1.5th order differential stripping analysis.Adetection limit 2×10^-10 mol/Lof estrogens was estimated after an adsorptive accumulation time of 10 min.The peak height is directly proportional to the concentration of estrogens in the range of 1×10^-6～1×10^-9mol/L.The method has been used for the assay of estriol in urine samples.

Key words: Estrogen, 1.5th order differential stripping analysis, Hanging mercury electrode, Urine
