    Description / Table of Contents: Effect of Temperature and Presence of Foreign Ions on the Kinetics and Mechanism of the Goethite Formation in Liquid PhaseWe studied the influence of temperature and addition of some foreign ions on the kinetics of transformation of the goethite in sulfate medium by slow air bubbling. The temperature up to 70°C does not influence the kinetics of oxidation; this proves that the transfer of oxygen taken place through the liquid phase.Manganese and colbalt cations impede the formation and the growth of αFeOOH crystallites. Citrate and phosphate anions both hinder this transformation.
    Notes: Ce travail est consacré à l'étude de l'influence de la température et de l'addition des ions étrangers sur la cinétique de formation de la goethite en milieu acide par aération. La température jusqu' à 70°C n'influence pas la cinétique de cette oxydation, ce qui prouve que le transfert d'oxygène se fait par la phase liquide.Les cations manganèse et cobalt ralentissent la formation et la croissance de αFeOOH. Les anions citrate et phosphate qui augmentent la solubilité du fer(III) en solution sont défavorables à la transformation de l'hydroxyde de fer(II) en goethite.
