    Ferrihydrite silicide is widely used to realize contact terminals of integrated circuits and is usually formed by ex-situ heating treatments in-situ reactions during sputter deposition of a ferrihydrite with SiO2 of diatomite have been investigated in this work, by means of x-ray diffraction , x-ray fluorescence , infrared spectroscopy, , scanning electron microscopy. Diatomite which will be modified by iron “ the deposit of ferrihydrite on raw diatomite by FeCl2, and NaOH. Comparison of XRD results proves that raw diatomite has an irregular structure but it becomes more regular at ferrihydrite modified to obtain ferric oxides differents phases from cristallinities are: ferrihydrite , maghemite, magnetite, akaganeite,hematite, goethite, and schwertmannite. Kinetics photodegradation ( photocatalytic degradation) depend a pH solution Vat Green 03 textile dye. It is more important with low pH (pH= 4).Ferrihydrite modified diatomite ( DMF1) offer a great potentials for dyes eliminations and their wastewaters
