A simple colorimetric method has been developed for the detection of lead (Pb) 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 which results in a change in the color of the functionalized gold nanoparticles. The change in color and the amount of Pb 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 in water samples and the results compared to that of measurement carried out with Atomic Absorption Spectroscopy.
