description

The determination of trimethoprim in the presence of dyphylline, proxyphylline, theophylline and caffeine by the linear absorbances method is described. Collinear couples of wavelengths, for the interfering dyphylline-proxyphylline-theophylline-caffeine system (in H2SO4, 0.05 mol/L), are provided in order to allow the determination of the analyte in the presence of these interfering substances.
