Two flow-injection methods for the fluorimetric determination of penicillamine and tiopronin are proposed. The procedures are based on the oxidation of these drugs by thallium(III). In hydrochloric acid medium the fluorescence of thallium(I) formed in the oxidation of penicillamine or tiopronin is m
A flow-injection configuration for the fluorometric determination of Novalgin (dipyrone) is proposed. The procedure is based on the oxidation of Novalgin by cerium(IV). The fluorescence native of cerium(III) formed in the oxidation of Novalgin is monitored. Lineal calibration graphs were obtained be
