Abstract
Salicylfluorone forms colored compounds with rare earths in a nearly neutral medium. The solutions follow Beer's law. Salicylfluorone is a more selective reagent as compared with arsenazo-1. The photometric determination of certain rare earths and their total with salcylfluorone is possible in the presence of sulfosalicylic acid to mask calcium and magnesium. (auth)
