 In this study, the MCM-48 mesoporous material was used as an active adsorbent for the removal of four-nitroaniline for nitrobenzene amine from wastewater. Characterisation of the material included SEM, EDAX, XRD, BET, PSD, and FDIR. The material was tested in batch experiments using different concentrations of four-nitroaniline and the results indicated that the material had a high affinity for the compound. The Langmuir isotherm best described the adsorption data with a maximum uptake of 90mg per G. The kinetic data supported the pseudo-second-order model indicating that the adsorption process was chemical in nature. Overall, these results suggest that MCM-48 can be used as an effective adsorbent for the removal of four-nitroaniline from wastewater. This article was authored by Nisrin S.
