  Iron Pillared Clay for Sorption of Toluene in Aqueous Solution: Kinetics and Equilibrium Studies

  By Emole, P. O, Kelechi Emmanuel Onwuka, Emeruwa, C. N.

  Abstract: The adsorption of toluene using unmodified and Fe-pillared clay were investigated in this study using UV/Visible, FT-IR spectroscopic measurements and batch adsorption process. The framework vibration of the clay before and after pillaring were determined using FTIR spectra. Effect of Contact time and initial and various concentration of toluene at constant temperature were investigated. The experimental data were studied using equilibrium isotherm (Langmuir and Freundlich) and kinetics models (pseudo first …
