The aim of this work is to synthesize, characterize, and evaluate the influence of two pillared bentonite (PILC) viz. Iron pillared bentonite (Fe-PILC) and Aluminium Pillared bentonite (Al-PILC) on cationic dye removal. The PILCs were investigated using X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Brunauer-Emmer Teller (BET) analysis, Thermogravimetric analysis (TGA), and Scanning Electron Microscopy (SEM). The parent clay and synthesized PILCs are used as adsorbents for Malachite Green (MG) and Chrysoidine-Y (CY) dyes. In Al-PILC, maximum dye adsorption capacities at equilibrium were 90.080 mg g-1 for MG and 76.369 mg g-1 for CY, Whereas, in Fe-PILC, it were 60.518 mg g-1 and 57.041 mg g-1 for MG and CY, respectively. Parent clay as well as the pillared clays followed Freundlich isotherm model and PSO model. |
