Industrial dye waste waters pose some hazards and environmental problems. Colour is the first characteristics of such effluent which is easily detected. The presence of dyes in water affect its nature, inhibiting sunlight penetration into stream and reducing the photosynthetic reaction[l]. Colour removal is a major problem because most of the dyes are resistant to biological degradation due to their complex structure and xenobiotic properties. Adsorption techniques by using clay derivatives, have proven successful in removing coloured organic species, in terms of initial cost, simplicity of design, ease of operation and insensitivity to toxic substances comparatively to biotechnological processes [2, 3]. Clay derivatives have been accepted as one of the most appropriate sorbents for their easily preparation and regeneration.
