Abstract

A novel magnetic adsorbent for Pb²⁺ was synthesized based on 4′-aminobenzo-18-crown-6 (AB18C6) and Fe₃O₄–CHO via the Mannich reaction. It showed excellent adsorption and selectivity for Pb²⁺, and the established MSPE method had excellent potential, displaying the selective determination of trace Pb²⁺ from apples, milk and rice.
