The inevitable expansion of industries for development is at the cost of release of industrial pollutants into the natural reservoirs of the environment. Biosorption is becoming an important component in the integrated approach to the treatment of aqueous effluents. The adsorption properties of Gallus Domesticus are determined as a function of batch operating conditions including contact time, solution initial concentration and temperature. Metal ion fixed Fourier transform infrared spectroscopy spectrum depicted amine, alcohol, carboxyl, and carbonate ion as active sites for metal sorption. Augmentation of removal capacity to 5 and 17% is tailored by esterification and acetylation of different surface functional groups of the base matrix. Kinetics is dissected through diffusion-based kinetic models, and best fit was figured out for Elovich equation. The thermodynamic relationship draws that enthalpy (ΔH° 45.48 KJ/mol) and entropy (ΔS° 153.32 J/mol K) are positive and entropy of the system is much larger than enthalpy. Results propose alteration of domestic waste into economical adsorbent for commercialization with no processing in the efficient removal of cadmium from wastewater.
