Lipoic Acid Decorated Gold Nanoparticles and Their Application in the Detection of Lead Ions

A simple colorimetric method has been developed for the detection of lead (Pb(2+)) in water samples using lipoic acid-functionalized gold nanoparticles. The lipoic acid-functionalized gold nanoparticles are induced to aggregate in the presence of the Pb(2+) which results in a change in the color of...

description A simple colorimetric method has been developed for the detection of lead (Pb(2+)) in water samples using lipoic acid-functionalized gold nanoparticles. The lipoic acid-functionalized gold nanoparticles are induced to aggregate in the presence of the Pb(2+) which results in a change in the color of the functionalized gold nanoparticles. The change in color and the amount of Pb(2+) producing the change could be monitored via UV-visible spectrophotometry. A good correlation coefficient of 0.9927 was obtained for the calibration curve of the colorimetric method. The method was applied in the determination of Pb(2+) in water samples and the results compared to that of measurement carried out with Atomic Absorption Spectroscopy.
