Abstract

A two-dimensional nanoflake (Fe/Cu-TPA) was prepared through a simple ultrasonic-centrifuge method. Fe/Cu-TPA has prominent performance on the removal of Pb²⁺ with low consistences. More than 99% lead (II) (Pb²⁺) was removed. The adsorption equipoise was established within 60 min for 50 mg L^-1 Pb²⁺. Fe/Cu-TPA shows excellent regenerability with 19.04% decline of Pb²⁺ adsorption competence in 5 cycles. There are two models for Fe/Cu-TPA adsorption of Pb²⁺, pseudo-second-order dynamic model and Langmuir isotherm model, with a utmost adsorption competence of 213.56 mg g^-1. This work offers a new candidate material for the industrial-grade Pb²⁺ adsorbents with promising application prospect.
