Study on the Adsorption Properties of D113 Cation Exchange Resin for Zn2+
The adsorption properties of D113 cation exchange resins on Zn2+ were researched systematically using the traditional batch method. Under different initial Zn2+ concentrations, reaction times, and temperatures, the adsorption efficiency and capacity were measured respectively. In addition, the adsorption equilibrium of D113 resin for Zn2+ obeyed the Langmuir adsorption isotherm model well; the adsorption process agreed with pseudo second-order kinetics model, and was dominated by chemisorption; ΔH＞0 and ΔG＞0 at different temperatures indicated the adsorption was a spontaneous endothermic process in nature. Finally, SEM and FT-IR were properly used to characterize the resins.
