Pyridine-Functionalized Fe^sub 3^O^sub 4^ Nanoparticles as a Novel Sorbent for the Preconcentration of Lead and Cadmium Ions in Tree Leaf as a Bioindicator of Urban Traffic Pollution

We have developed a facile and highly sensitive sorbent for cadmium and lead ions. It is based on Fe^sub 3^O^sub 4^ nanoparticles functionalized with a derivative of picoline and was characterized by scanning electron microscopy, differential thermographic analysis, and elemental analysis.

Description
Summary:We have developed a facile and highly sensitive sorbent for cadmium and lead ions. It is based on Fe^sub 3^O^sub 4^ nanoparticles functionalized with a derivative of picoline and was characterized by scanning electron microscopy, differential thermographic analysis, and elemental analysis. The material can be applied to the preconcentration of lead and cadmium ions. Factors such as the type, concentration and volume of eluent, the pH of the sample solution, the time for extraction, and the volume of the sample were studied. The effects of a variety of ions on preconcentration and recovery of these ions were also investigated. The ions were determined by FAAS, and the limits of detection are
