| Abstract | This work investigated the potential use of organo-pomelo peel(OPP) biomass prepared by adsolubilization to removeRhodamine B (RB), a common dye in industries, from aqueous solutions. The OPP and precursor were characterized byBrunauer-Emmett-Teller method, Fourier transform infrared spectrometer, and scanning electron microscope. The biosorption ofRB strongly depends on the initial dye concentration, pH, temperature, and contact time. The optimum condition was observed atpH6.0, 35?C and 40 min. The equilibrium data was analyzed by using Langmuir, Freundlich, and Temkin isotherm models. Thepseudo-first order, pseudo-second order, and intra particle kinetic models were applied to study the kinetic behavior. Thethermodynamic study showed that the biosorption process was exothermic and spontaneous. Results indicated that the OPP wasan effective adsorbent for removal of RB from aqueous solution. |
