[Determination of analginum in medicine by ironic rhodanate spectrophotometry].
Analginum in preparations was determined by the ironic rhodanate fading spectrophotometric method, based on Fe3+ reduced into Fe2+ by analginum and reacting on potassium rhodanate. The obtained results were in agreement with those of the iodine titration method and the ultraviolet photometric method.
