The Adsorption of Nickel from Wasterwater Samples on Grass Carp Scales

Article Preview

Abstract:

The adsorption of grass carp fish scale was used to remove Ni2+ in the heavy metals wastewater. The effect of shaking time, temperature and pH value on the adsorption Ni2+ onto fish scale was investigated. The maximum biosorption was both observed at pH 6.3 on the eggshell membrane. Optimal adsorption capacity was 120.9 mg g-1 at initial concentration 100 mg L-1. Characterization of the biosorbent fish scales was performed using scanning electron microscope (SEM), and Fourier transform-infrared (FTIR) spectroscopy. The mechanism for the adsorption was studied. The adsorption of Ni2+on to fish can be described by Langmuir isotherm model when the concentration of Ni2+ under 100mg•L-1.
