摘要：

Lead contamination is a threat for the environment and human health due to lead non-degradability and non-detoxification. Therefore, methods for efficient removal of lead from contaminated waters are needed. Here, a novel material has been synthesised by surface functionalization of magnesium-aluminum layered double hydroxide with citrate (citric-LDH) and applied to the efficient removal of lead from aqueous solutions. Effects of ionic strength and temperature on the adsorption have been evaluated. Results show that lead adsorption by citric-LDH can be used for lead pollution cleanup. Adsorption kinetics were simulated using a revised model. Simulation results show that citric-LDH adsorb lead ions through a more efficient and time-dependent pathway, leading to the rapid and efficient removal of lead ions.
