摘要：
A method for the determination of carbimazole involving its reaction with iodine in an alkaline medium is presented. In volumetric titration with potentiometric end-point detection the range of determination is 30-500 mu mol (5.6-93 mg). In coulometric titration using biamperometric end-point detection, 0.5-20 mu mol (0.09-3.7 mg) of carbimazole was successfully determined. The coulometric titration was applied to the determination of carbimazole in tablets.
