“…A wide range of non living biomass like bark, lignin, peanut hulls as well as live biomass like fungi, bacteria, yeast, moss, aquatic plants and algae has been used as biosorbent [9][10][11][12]. For removing heavy metals both live and dead biomass can be used, but dead biomass offers advantages, as it is not subjected to operational environmental shocks like change in pH, temperature, presence of inhibitors etc.…”

In this work the potential of fish scales as a suitable biosorbent for removal of Cr(VI) ions from aqueous solutions was investigated at various temperatures. The influence of temperature on equilibrium, kinetics as well as thermodynamic parameters was investigated. Various isotherm models such as Langmuir, Freundlich, R -P, D -R, Temkin and Halsey were used for the mathematical description of the biosorption of Cr(VI) ions onto fish scales. It was observed that Freundlich model exhibited the best fit to experimental data.Amongst the various kinetic models tested, the pseudo-first-order kinetic model represented the best correlation for the biosorption of Cr(VI) onto fish scales at various temperatures. In addition, various thermodynamic parameters such as ∆G o , ∆H o and ∆S o were also determined. The biosorption of Cr(VI) was found to be a spontaneous and endothermic process.

“…Villanueva-Espinosa et al (2001) found that the power law model can be used to predict the uptake rate for the various metal ions. The pseudo second order kinetic model gave good fit to the biosorption system studied by Nadeem et al (2008) and Srividya and Mohanty (2009).…”

This study focused on the effect of various experimental parameters like adsorption kinetics, effects of pH, temperature, initial Cu(II), biosorbent dose and agitator speed on biosorption of Cu (II) from aqueous solution onto Catla catla fish scales. Analysis of Fourier-transform infrared (FTIR) spectrum, scanning electron microscopy (SEM) images and energy-dispersive X-ray (EDX) spectroscopy suggested that both organic functional groups and inorganic constituent take part in the Cu (II) uptake process. Both the linear and nonlinear forms of the Langmuir and Freundlich adsorption isotherm models (at low concentration) predicted the equilibrium adsorption isotherm data fairly well. The maximum Cu (II) adsorption capacity of fish scale was determined to be 79.35 mg/g at 40°C and pH 5.5 by nonlinear regression. A mathematical model developed assuming the adsorption process to be diffusion controlled gave satisfactory fit to the experimental batch kinetic data.

“…Organic compounds comprise 40-90% in scales and most of them are collagen, regardless of fish species 13 . The functional groups in the fish scale structure, such as phosphate, carboxyl, amine and carbonyl, are supposed to be involved in the sorption process 14 . At present, large quantities of fish scales are produced in fish shops and fish-processing factories.…”

“…So, the active functional groups on the fish scale surface which involve in the sorption process are carboxyl (-COOH), amine (-NH 2 ) and phosphate (PO 4 3ˉ) groups 14 . The results of studies on adsorption isotherms at different pHs show that the adsorption of BR on fish scale surface is decreased with increasing pH of the solution (Fig.…”

Removal of brilliant red (C. I. Reactive Red 2) from aqueous solutions by adsorption on fish scales of Labeo rohita was investigated. Batch adsorption experiments were carried out under different experimental conditions such as contact time, initial concentration of dye solutions, temperature and pH of the solution. The optimum pH for the adsorption experiment was found to be 7.2. The equilibrium time for the adsorption of brilliant red (BR) on fish scales was estimated and found to be three hours. The amount of brilliant red adsorbed on fish scale surface decreased with increasing pH and temperature of the solution. The negative value of differential heat of adsorption suggests that the adsorption process is exothermic. Langmuir adsorption isotherm was found to fit the experimental data better than that of the Freundlich adsorption isotherm.
