Objective: There are différents méthode for moving dyes from contaminated environment and textile industries, the gold of this study is using of nano Ilmenite with anti bacterial properties for dye degradation.

Method: The Ilmenite nanoparticles were produced and their catalytic activities were determined by the color change of several dyes. The prepared FeTiO₃ nanoparticles have hexagonal structure with average size of ~21 nm.

Results: The results indicated that although the Ilmenite has catalytic activity for photo-oxidation of dyes but Nano- Ilmenite has higher activity for dye removal. Dye removal by Nano-Ilmenite for Malachite Green, Alkaline Fuchsin and Coomassie Blue were 97% 50% and 100% respectively. Ilmenite removed Alkalin Fusion in lower rate but increased the color of Malachite Green and Coomassie Blue. Although Ilmenite had antibacterial activity but antibacterial activity of Nano-Ilmenite was 50% more.

Conclusion: These data indicate that this Ilmenite soil can be used for remediation of contaminated area.
