WebTo confirm this scenario, t he possible displacement process es of Ag ion in AgCr 2 S 4 as well as its H-passivated cases are simulated by the NEB method. The corresponding energy profile are shown in Figure 5. Obviously, unilateral s adsorption breaks the centro- symmetry and forces Ag to shift away from H, resulting in an asymmetric potential ... WebIn this work adsorption of heavy metal ions (Cu2+, Pb2+, Zn2+ and Ni2+) from aqueous solution by chitosan was investigated in a batch reactor. Three commercially different viscosity chitosans were used as adsrobents. pH value, adsorption temperature, time and initial concentration had affected adsorption efficiency of metal ions.
