Title Of Article :
THE INVESTIGATION OF THE ADSORPTION OF ACID BLUE 121 ON BANANA SHELL IN A BATCH SYSTEM
Abstract :
In this study, the effects of initial pH, temperature, initial dye concentration and adsorbent concentration to the adsorption of Acid Blue 121 (AB 121) on banana shell (MK), an agricultural waste, was investigated in a batch system. It was obtained that the equilibrium data of AB 121adsorption on MK was well fitted to the Langmuir isotherm model and the maximum monolayer adsorption capacity of MK was to be 141 mg/g. It was concluded that the kinetic of AB 121 adsorption on MK could be described with the pseudo second order kinetic model, and also the external and intraparticle diffusion were effective in the actual adsorption process. The thermodynamic parameters of AB 121adsorption on MK were determined and it was observed that the adsorption of AB 121 on MK was exothermic and spontaneous in nature. The characterization studies of adsorbent were carried out with FTIR, SEM and EDX analysis methods.
