dc.description.abstractMontmorillonite (Mt) was used to remove copper (Cu2+) ion from wastewater stream generated from industrial effluents. This clay was modified (Mt-TOA) by using an amine-based solvent, trioctylamine (TOA). Equilibrium and kinetic experiments were carried out to determine the effect of adsorbent amount (w, 0.05 g to 0.3 g for Mt, 0.001 to 0.006 g for MtTOA), initial Cu2+ ion concentration (C-0, 8 mg.L-1 to 16 mg.L-1), pH (2 to 10), and contact time (t, 10 to 90 min) on the capacity of both adsorbents. With an increase in the adsorbent amount, the uptake capacity of Mt and Mt-TOA for Cu2+ ion was found to decrease but with an enhancement in the removal efficiency. The optimum amount of Mt and Mt-TOA was found to be 0.1 and 0.001 g, respectively. A better adsorption of Cu2+ ion was observed at low pH value of aqueous solution, and was found to decrease with an increase in the value of pH. In the kinetic experiments, the amount removal of Cu2+ ion reached to a constant value of 75.62 % with Mt (0.1 g) and 80.12 % with Mt-TOA (0.001 g) after 70 min. Equilibrium and kinetic data were analyzed by using eight different isotherm (Langmuir, Freundlich, Elovich, Temkin, Dubinin-Radushkevich, Redlich-Peterson, Toth, and Sips) and two different kinetic (pseudo-first-order and pseudo-second-order) models, respectively.en_US
