Abstract
A bivariate calibration method. has been applied to the simultaneous determ ination of U(VI) and Th(IV) ions as complexes with carminic acid by visible absorption spectrophotometry.. The bivariate calibration method was applie d satisfactorily to the determination of these ions in synthetic solutions simulating sulfuric acid leach solution obtained from uranium-thorium ores and the results were compared with those given by first derivative spectrop hotometry. No significant advantages of any method were found.
