Abstract: Present study was accomplished toprospect the viability of using the montmorillonite (Mon) nanoparticles as anadsorbent to remove the Ampicillin under various experimental conditions.Physico-chemical features of the Mon-nanoparticles were discovered. Langmuir,Freundlich, Temkin and Dubinin–Radushkevich isotherms were applied to portraythe data obtained from the adsorption studies. The findings showed that thehighest R2 values were related to Langmuir and Dubinin–Radushkevichisotherm models. The greatest adsorption capacity (qe) for Langmuir andDubinin–Radushkevich isotherm models were recognized to be 134.
48 mg/g and141.22 mg/g, respectively; and the separation factor was calculated to be 0.113which is indicative of a favourable sorption. Temkin Isotherm model clarifiedthat the heat of sorption process was 34.61 J/mol; and the mean free energycalculated by Dubinin–Radushkevich isotherm model was anticipated to be 2.
56Kj/mol which these undoubtedly demonstrate the physisorption process forAmpicillin adsorption experiments.Results and discussionThetable 1and 2 represented the chemical composition and physicochemicalproperties of the Mon-nanoparticles, respectively. As it can beseen in Table 1, Montmorillonitehas considerable levels of SiO2 (57.7%) and Al2O3(18.1%) and the quantityof other metal oxides is observed to be lesser than 20%.
The investigation of the surfacephysical morphology ofwaste and 71 Montmorillonite were fulfilledusing the scanning electron microscopy (SEM) technique. Fig 2 shows the SEM images of the Montmorillonite. Furthermore, it was found that the surface area of Montmorillonite is 245.5m2/g.Adsorptionisotherms: The adsorption data were analyzed to see whether the isotherm obeyed theLangmuir, Freundlich, Dubinin-Radushkevich (D-R) and Temkin isothermmodels equations 32-36: 71 Waste and????
