Removal of Aniline from Aqueous Solution by Adsorption on a Modified Montmorillonite Clay Kinetic and Thermodynamic Studies

This work concerns the application of treated montmorillonite clay in adsorption Aniline as an organic pollutant wastewater. The characteristics were evaluated by X-ray Fluorescence (XRF), diffraction (XRD) patterns, Fourier-transform infrared spectroscopy (FTIR) and Thermogravimetric Analysis (TGA). Additionally, effect different factors such type treatment, adsorbent dosage, contact time, solution temperature pH studied. experimental data was two kinetic models; pseudo-first pseudo-second order. results indicated that followed pseudo-second-order models with coefficient R2 = 0.9928. equilibrium time obtained after 3h. thermodynamic parameters refer to on modified endothermic chemisorption. Because advantages abundance speed process, this method could be used effectively remove aniline from
