摘要

High levels of lead in the environment threaten human health,plants,soil quality and ecological systems.Because heavy metals are not biodegradable,they must be removed from water3'4.Adsorption is a suitable process with the use of nanomaterials(NM)as adsorbents.In this work,the adsorption on ZIF-8 and NMZIF-8 for the elimination of Pb~(2+)ions from aqueous solution is studied.The lead ions adsorption properties on ZIF-8 and NMZIF-8 were then explored with respect to kinetics,isotherms,thermodynamics,mechanism,and recycling for the first time.The effect of the pH and the temperature of the solution on the removal efficiency is also studied.This work demonstrates that NMZIF-8 can be a good candidate as an adsorbent for the elimination of Pb~(2+)ions from water.
