Pincer ligand mesoporous material in heavy metal adsorption for environmental purposes.

ABSTRACT: Based on our previous results obtained on the coordination of bis-pyrazolyl bis-acetate pincer ligand towards heavy metals, mesoporous silica (pore size: 60 Å) was functionalized with a new NNN pincer ligand prepared through three surface modification steps to obtain a novel mesoporous material @SiA₃. This study reports the synthesis and the application of @SiA₃ for the removal of heavy metal ions (Pb²⁺, Cu²⁺, and Cd²⁺) from aqueous media. The obtained material @SiA₃ was characterized by a series of analytical techniques including FT-IR, solid-state NMR ¹³C and ²⁹Si, BET, EA, SEM and BJH which all confirmed the successful grafting. Following the characterization, batch adsorption experiments were conduc
