title: Investigation of the composition of complexes and the stoichiometry of non-complex reactions by flow injection method.
abstract: Combining the Asmus straight-line method with the flow injection (FI) technique, a new FI-straight-line method is established to investigate the formulas of the blue, the purple and the red complexes formed by iron(III) and Tiron in different pH solutions. Using the proposed FI-straight-line method, the stoichiometries of cyanide and harbituric acid for producing the intermediate and the final product of the chromogenic reaction of cyanide with pyridine-barbituric acid reagent are also studied.
