Characterization and application of natural Moroccan material for methyl violet 2B dye removal from aqueous solution.

In this paper, a natural Moroccan material from the Nador area in the north east of Morocco was studied as an adsorbent to remove methyl violet 2B dye from aqueous solutions. This material has never been studied before in this region, and it will be used in its raw state. It was collected and characterized by X-ray diffraction, FTIR spectroscopy, scanning electron microscopy, X-ray fluorescence, thermal analysis, N gas adsorption-desorption, pH, and Brunauer-Emmett-Teller (BET).
