Terephthalic acid reformed Al/Zn metal organic nanoflake was prepared and functionalized with trie-thylamine(T-AlZn).Without adding terephthalic acid,there was no product of metal organic nanoflake.T-AlZn has a remarkable performance in removing trace lead(Ⅱ)ions(Pb2+).The adsorption equipoise with the removal rate ≥97％was reached within 35 min.The removal rates of T-AlZn for Pb2+declined by only 16.73％after four regenerations.The adsorption of T-AlZn for Pb2+follows the Langmuir isotherms model and pseudo-second-order dynamics model.The utmost adsorption competence was calculated as 215.27 mg g-1.The T-AlZn adsorbent exhibits a bright prospect in the adsorption for Pb2+and is a considerable candidate in the disposal of industrial sewage.
