Abstract

The adsorptive stripping voltammetry of corticosterone was studied in <TEX>$1.0{\times}10^{-2}M$</TEX> sodium hydroxide as supporting electrolyte. The analytical conditions were as follow : 360 sec. for deposition time, -8.0 volts deposition potential, medium size mercury drop, and 20mV/sec scan rate. Calibration curve has shown a linearlity in the range of <TEX>$5.0{\times}10^{-9}M$</TEX> to <TEX>$8.0{\times}10^{-7}M$</TEX> and the detection limits have been <TEX>$9.5{\times}10^{-10}M$</TEX> for corticoterones. This method has shown such a high sensitivity even in dilute solution that has been useful for analyzing sex hormones in medical supplies without interference of additives.
