In this work, we evaluated the waste red mud as the potential catalyst for treating the hazardous compounds. In particular, several physicochemical pretreatments such as acid aqueous solution and thermal air were employed to properly modify the textural properties of the waste red mud. Several well-known methods including nitrogen adsorption, XRD, ICP-AES, FT-IR, SEM, TEM an TPR were used to characterize the waste red mud and its modified red mud. Our results indicated that the catalytic activity of the waste red mud was highly dependent on the pretreatment methods applied. The red red mud pretreated with acid aqueous solution had a high potential as an alternative catalyst for removing the volatile organic compounds.
