Monitoring Lead–Phosphorus Interactions Through ³¹P-NMR Used as a Sensor in Phosphine Functionalized Silica Gel Adsorbent

A triphenylphosphine-functionalized silica gel material, optimized for lead adsorption, was synthesized via a one-pot sol–gel reaction and characterized using FTIR and solid-state ¹³C and ²⁹Si NMR and XPS spectroscopy. The interaction between lead cations and phosphine groups w...
