Abstract

Terephthalic acid reformed Al/Zn metal organic nanoflake was prepared and functionalized with triethylamine (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.
