Adsorption for the Removal of Malachite Green by Using Eggshell Membrane in Environment Water Samples

Abstract:

Article Preview

The performance of native eggshell membrane in removing of malachite green (MG) from aqueous solution was investigate. The effect of pH, adsorbent concentration, temperature, and contact time were performed by static testing. The maximum biosorption was both observed at pH 6.0 on the eggshell membrane. Optimal adsorption capacity (89.72 mg g-1) at initial concentration 100 mg L-1 and rate (98.69%) was obtained at pH 5.5. Characterization of the biosorbent eggshell membrane was performed using scanning electron microscope (SEM), and Fourier transform-infrared (FTIR) spectroscopy. The kinetic and equilibrium studies suggest that the adsorption follows Langmuir isotherm model. Desorption studies revealed that MG could be well removed from wastewater.
