Dithiocarbamate-immobilized silica coated magnetic Fe3O4 nanoparticles for solid-phase extraction of lead in shellfish

This study describes the synthesis, characterization and application of dithiocarbamate-immobilized silica coated magnetic nanoparticles (Fe3O4-CPTS-DTC) as an adsorbent for separation and preconcentration of trace lead in shellfish. The adsorbent was characterized using FTIR, SEM and XRD. The ext...
