The High Efficiency of Anionic Dye Removal Using Ce-Al13/Pillared Clay from Darbandikhan Natural Clay

Abstract: Natural clay from Darbandikhan (DC) was evaluated in its natural form, after acid activation (ADC), and after pillaring (PILDC) as a potential adsorbent for the adsorption of methyl orange (MO) as a model anionic dye adsorbate. The effect of different clay treatments was investigated using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Scanning Electron Microscope (SEM) and Fourier-Transform Infrared Spectroscopy (FT-IR), and N2 physisorption analysis. Both acid activation and pillaring resulted in a signi… Show more

“…At pH = 8, about 80% of the dye was removed at 5 min with 3 mg of the adsorbent. As the MNCTS dose was increased, the MG removal percentage enhanced because of the increase in the total number of the adsorption sites 27 …”

“…As can be observed in Figure 11, the MG removal percentage raised steadily with increasing temperature, reaching the highest removal rate at 45°C and then reached to equilibrium. The increase in the dye removal efficiency is because of the increase in the rate of MG molecules diffusion from the bulk solution to the MNCTS surface at higher temperatures 27 . In addition, the increase in the mobility of the MG molecules can generate enough energy to interact with the active sites at the adsorbent surface 51 .…”
