Abstract

The determination of sex hormones by adsorpive stripping voltammetry in $1.0{\times}10^{-2}M$ sodium hydroxide as supporting electrolyte has been investigated in the conditions as follows : 240sec. for deposition time, -0.80 volts deposition potential, medium size mercury drop, and 20mV/sec scan rate. Calibration curve has shown a linearlity in the range of $5.0{\times}10^{-9}M$ to $8.0{\times}10^{-7}M$ and the detection limits have been $8.0{\times}10^{-10}M$ for progesterone and $1.4{\times}10^{-9}M$ for testosterone propionate. This method has shown such a good sensitivity even in dilute solution that has been use full for analyzing sex hormones in medical supplies without interference of additives.
