Description	Glassy carbon electrode, modified with cobalt(I I) cyclohexylbutyrate monohydrate immobilized in polystyrene matrix is usable for determination of thiol group bearing compounds both in oxidized and reduced forms using catalytic stripping voltammetry. The measurements are carried out in acetate buffer (pH 4.3) containing Tween 40. After the accumulation step at - 850 mV vs. Ag/AgCl a peak at - 170 mV is observed on linear sweep voltammogram, the height of which is proportional to the concentration of added thiol. Addition of carbon nanotubes into polystyrene film enhances the sensitivity of the modified electrode. The detection limit is 1 x 10(-6) mol dm(-3) for all studied thiols. The electrode can be regenerated by exposing it to the potential between 300-600 mV.
