چکیده:
In this study, sugar beet pulp was used to remove thallium (I) from aqueous solution. This sorbent was modified by various chemical agents, including H2SO4 NaOH, HNO3, NH3, NaCl, NaHCO3 and HCl. Among the various chemical modifiers NaOH was chosen. Experimental data were analyzed by the Langmuir, Freundlich, Harkins-jura, Halsy, Dubinin-Redushkevich, Temkin, Generalized biosorption, Henderson and Frumkin isotherm. For modified Sugar beet, equilibrium data fitted well with the Langmuir model with maximum capacity 185.18 mg/g. The effect of four main factors pH, Temperature (T), sorbent dosage (m) and initial concentration of Tl (C0) were studied. Various thermodynamic parameters such as [Formula] and [Formula] were calculated indicating that this system was spontaneous and exothermic process. Reusability of sorbent was examined by the adsorption studies.
