Abstract

In this study, the removal of Malachite Green synthetic dye from aqueous environment was investigated using Sparus aurata as a source of fish bone. The removal efficiency of the adsorbent was investigated as a function of time and dye concentration via batch method at room temperature. The correlation coefficient values indicate that the data fit the Freundlich Isotherm (R-2= 0,9861) better than the Langmuir Isotherm (R-2=0,3695). The thermodynamic and reaction kinetic of Malachite Green from the aqueous solution were determined and correlated to pseudo-second order kinetic models and the experimental data revealed that pseudo-second order kinetic model is available to experimental data. Gibbs free energy value was found to be -1.308 kJ/mol and indicating the spontaneity of the system. Thermodynamic parameters exhibited that the adsorption process was spontenous (Delta G
