| Abstract | A new spectrophotometric method for the determination of thionicotinamide and ethionamide is proposed. The method employs the reaction between these compounds and vanadium-PAR complex. The composition of the complexes formed is V:PAR:ligand = 1:1:1. The method described makes it possible to determine ethionamide and thionicotinamide in a concentration range of 0.2-20 J.tg mlt . The method proposed is sensitive and reproducible. It permits the determination of thionicotinamides in the presence of many organic compounds in great excess. The use of this method to determine ethionamide in drugs, blood serum and urine is proposed. |
