“…As can be seen, the pseudo second-order kinetic equation is representing adsorption kinetic well for each system. As many precious metal ion adsorption studies (P. Cyganowski et al, 2017;Fayemi et al, 2013;Sivrikaya et al, 2017;Urucu et al, 2019;Vojoudi et al, 2017;Zhang et al, 2019;Zhao et al, 2019), Kanagare et al studied Pd (II) adsorption onto commercial dithio diglycolamide impregnated XAD-16, it is represented better by a pseudo second order kinetics equation (Kanagare et al, 2016). At high initial concentrations, the deviations in the intraparticle diffusion calculated qe values is very high.…”

“…Zhang at al. (Zhang et al, 2019) obtained an adsorption capacity of 459.29 mg/g with the 2,6-diaminopyridine functionalized PVP polymer with Au (III) chloro complexes. Chemin et al (Chemin, Moreau, Cathala, & Villares, 2020) are reported of Au (III) adsorption with polyamine dendrimer bonded cellulose polymer and 10 times more adsorption than normal cellulose.…”

Adsorption of gold and palladium species containing chlorine ion species onto commercial N-(2-[bis(2-aminoethyl)amino)ethyl]aminomethyl−polystyrene polymer beads (TRIS) was investigated. The influence of the pH, initial metal ion concentration, and contact time on the adsorption performance was examined in a batch adsorption experiment. To examine and discuss both the theoretical character of the metal ion adsorptions, Langmuir, modified Langmuir, Freundlich, Tempkin, Dubinin−Radushkevich, and nonlinear solutions of modified Langmuir and Redlich−Peterson isotherm models variables are calculated. The modified Langmuir monolayer adsorption capacities of the Pd(II) and Au(III) chlorine ions species were found to be 206.93 and 173.18 mg/g, respectively. The two metal adsorption kinetics fit the pseudo-second-order kinetic models. In thermodynamic calculations, the choice of different equilibrium constants with having a dimension is an important problem in the field. To overcome these problems, the modified Langmuir isotherm equilibrium constant was used for determination of thermodynamic parameters. Adsorption mechanism steps were characterized using Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The adsorbent is made to interact with each metal ion in the HCl solution electrostatic interaction and surface complex formation between the amine groups. The calculation of the thermodynamic parameters using the dimensionless modified Langmuir equilibrium constant was found to be more satisfying and reliable. Adsorptions of Pd(II) and Au(III) on TRIS beads were exothermic and endothermic spontaneous processes, respectively.

Adsorption of gold, rhodium, platinium, and palladium species containing chlorine ions species onto commercial N-{2-[Bis(2-aminoethyl)amino]ethyl}aminomethyl–polystyrene polymer beads (TRIS) were investigated. The influence of the pH, initial metal ion concentration, and contact time on the adsorption performance was examined in a batch adsorption experiment. Langmuir, Modified Langmuir, Freundlich and Freundlich, Dubinin–Radushkevich isotherm model variables are calculated. The Langmuir monolayer adsorption capacities of the Pd (II), and Au (III) chlorine ions species were found to be 204.5, and 168.5 mg/g, respectively. The two metal adsorption kinetics fit the pseudo-second order kinetic models. In thermodynamic calculations, the choice of different equilibrium constant and withal using dimension containing constant usage are an important problem in the field. To overcome these problems, the Modified Langmuir isotherm equilibrium constant is used at determination of thermodynamic parameters. Adsorption mechanism steps were characterized by using FT-IR, SEM, and EDS. The adsorbent is interacted with each metal ions in HCl solution electrostatic interaction and surface complex formation between the amine groups. The calculation of the thermodynamic parameters using the dimensionless modified Langmuir equilibrium constant calculated more satisfying and more reliable way. All thermodynamic parameters suggested that Pd (II) and Au (III) adsorptions onto TRIS beads was a spontaneous, physisorption.
