Determination of cyadox and its metabolites in plasma by adsorptive voltammetry.
Adsorptive stripping voltammetry was combined with separation of the surfactants by gel chromatography or solvent extraction for determination of the growth promotor, cyadox, and its metabolites in the plasma from pig blood. The procedure permits determination of the substance at concentrations from units to hundreds of ng per ml of plasma. The accuracy of the results was checked by comparison with radiochemical measurements.
