| 英文摘要 | A polyether sulphone (PES)-type chelating membrane containing aminophosphonic acid groups was fabricated for the purpose of Pb(II) removal from the aqueous solution. Effects of pH, initial Pb(II) concentration, temperature, contact time, thickness of membrane stack, flow rate, three coexisting cations (Cd(II), Ni(II) and Cu(II)), and three complexing reagents (citric acid, nitrilotriacetic acid and ethylenediaminetetraacetic acid) on the Pb(II) adsorption by the membrane were evaluated. The adsorption kinetics, adsorption isotherms and breakthrough curves with the presence of the six coexisting substances were studied. The adsorption-diffusion partial differential equations for Pb(II) adsorption were analyzed and verified by energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy. In addition, the reused performance of the membrane was evaluated. The presence of coexisting substances reduces the Pb(II) uptake, Cu(II) and ethylenediaminetetraacetic acid show a more remarkable interference than other cations and complexing reagents. The Langmuir and pseudo-second-order models are competent for the description in adsorption isotherms and adsorption kinetics; the breakthrough process can be described by the bed depth service time model. The Pb(II) adsorption is a spontaneous and exothermic process. When Pb(II) permeates through the membrane stack, the decrease of this metal uptake along the axial depth direction is validated. |
