Abstract
Molar-ratio and Asmus methods for the determination of the stoicheiometry of complexes were adapted to flow techniques. The procedures were tested for LaIII-Arsenazo I, FeII-1,10-phenanthroline, ThIV-Thorin, ThIV-Alizarin S and CeIII-Arsenazo III. The method proposed is based on the merging of two solutions (metal and reagent), keeping the flow-rate of one of them constant and increasing the other stepwise. The graphs obtained and their theoretical basis are discussed.
