Amorphous manganese silicate/PVDF membrane in the diffusive gradient in a thin-film for selective monitoring of lead

Abstract

Herein, a simple co-precipitation and phase invasion technique was applied to prepare a MnSi-loaded PVDF membrane (PMn), which exhibited highly selective adsorption for Pb²⁺. By employing the PMn as the binding phase, the high selectivity and rapid desorption of PMn effectively achieved low-cost, in situ, and selective monitoring of bioavailable Pb.
