摘要:Mg-Fe layered double hydroxide (LDH) with a Mg/Fe molar ratio of 3 : 1 was synthesized by using a coprecipitation method and the sorption removal of Pb(II) by the LDH sample from Pb(NO(3))(2) solution was investigated. It was found that Mg-Fe LDH showed a good sorption ability for Pb(II) from Pb(NO(3))(2) solution, indicating that the use of LDH as a promising inorganic sorbent for the removal of heavy metal ions is possible. The sorption kinetics and the sorption isotherm of Pb(II) on the LDH sample obeyed the pseudo-second order kinetic model and Aranovich-Donohue equation, respectively. The sorption mechanism of Pb(II) on the LDH may be attributed to the surface-induced precipitation and the chemical binding adsorption, and the removal ability arising from the surface-induced precipitation is much higher than that from the chemical binding adsorption.
