Adsorption kinetics, isotherms and thermodynamics of aromatic amino acids in feather hydrolysate onto modified activated carbon

Dexing Wang,
Song Ding,
Wei Zhang
et al.

Abstract: The main objective of this study was to produce low cost activated carbons for the adsorption of aromatic amino acids (AA) from feather hydrolysate. By optimizing the static adsorption conditions (time, pH and concentration) of amino acids, the adsorption amounts of tyrosine and phenylalanine reached 15.2 and 20.1 mg/g, respectively, under optimal conditions. Furthermore, it exhibits excellent reusability as it maintains a removal efficiency of 82.0% and 82.8% for tyrosine and phenylalanine after being reused … Show more

“…The theoretical maximum adsorption capacity was found to be 11.071 mg•g −1 , which closely matches the measured maximum adsorption capacity of 11.44 mg•g −1 . The adsorption process of F-g-GMA-NMDG is accurately characterized by the pseudo-second-order kinetic model, suggesting that chemical adsorption is the primary factor limiting the rate of this process [41].…”
