Abstract
(PANI)-(Ag-Au) alloy nanocomposites (ANC) were synthesized by an interfacial polymerization method using ammonium persulfate
as oxidant at the water/chloroform interface. Ag+ and Au+ ions from the AgNO3 and HAuCl4 solutions were utilized in the formation of
PANI-(Ag-Au) ANC. The structural variations of silver and gold incorporated PANI were confirmed by X-ray diffraction (XRD). Particle
size and its distribution were determined from the transmission electron micrograph (TEM). The surface morphology and the bonding
nature of the above-prepared sample were studied by scanning electron micrograph (SEM) and Fourier transform-infrared (FT-IR)
respectively. The presence of Ag and Au metals in the sample was confirmed by EDX analysis. The thermal behavior of the alloy sample
was studied by thermogravimetric analysis. The adsorption behavior of the sample for heavy metal ions, such as Pb2+ and Hg2+, was
determined by atomic absorption spectrometry (AAS). The results showed the considerable adsorption of heavy metal ions onto the ANC.
