Adsorption of gold(III), platinum(IV) and palladium(II) onto glycine modified crosslinked chitosan resin
TL;DR: The correlation results suggested that the pseudo-second-order model was the best choice among all the kinetic models to describe the adsorption behavior of Au(III), Pt(IV) and Pd(II) onto GMCCR.

Adsorption of platinum (IV), palladium (II) and gold (III) from aqueous solutions onto l-lysine modified crosslinked chitosan resin
TL;DR: Kinetic data correlated well with the pseudo-second-order kinetic model, indicating that the chemical sorption was the rate-limiting step and the thermodynamic study indicated that the adsorption process is spontaneous and exothermic in nature.
