Fabrication of a Greener TiO₂@Gum Arabic-Carbon Paste Electrode for the Electrochemical Detection of Pb²⁺ Ions in Plastic Toys.

ABSTRACT: A novel greener methodology is reported for the synthesis of titanium dioxide (TiO₂) nanoparticles (NPs) using gum Arabic (Acacia senegal) and the characterization of the ensuing TiO₂ NPs by various techniques such as X-ray diffraction (XRD), Fourier transform infrared, Raman spectroscopy, scanning electron microscopy-energy dispersive X-ray, transmission electron microscopy (TEM), high resolution-TEM, and UV-visible spectroscopy. The XRD analysis confirmed the formation of TiO₂ NPs in the anatase phase with high crystal purity, while TEM confirmed the size to be 8.9 ± 1.5 nm with a spherical morphology. The electrode for the electrochemical detection of Pb²⁺ ions was modified by a carbon paste fabricated using the synthesized TiO₂
