Abstract

This study focuses on the removal of organic dyes, such as Malachite Green (MG) and Rhodamine-B (Rh-B) from an aqueous solution with the help of a novel adsorbent (activated carbon) with magnetic property prepared by used disposal paper cups (AC@PC) at 500°C. The synthesized AC@PC adsorbent was characterized by using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDS) and point of zero charge (pHZPC). Adsorption of MG and Rh-B onto the AC@PC adsorbent from aqueous solution was investigated systematically. Langmuir, Freundlich and Temkin isotherms were also studied, however, it has been observed that Langmuir isotherm model was best fitted for both the dyes, which describe the adsorption behaviour at equilibrium. Pseudo-first and pseudo-second order kinetic model describe the rate of adsorption. Kinetic study explained that the process of adsorption followed the pseudo-second order model. Thermodynamic parameters such as enthalpy (?H°), entropy (?S°) and Gibb’s free energy (?G°) were also studied and revealed that the adsorption of MG was endothermic, whereas adsorption of Rh-B was exothermic onto the AC@PC. The prepared adsorbent shows potentially high adsorption properties for both the dyes.
