Spin coated hexaammineruthenium(III)/Nafion/ITO electrodes for the determination of lead(II) and cadmium(II) via anodic stripping voltammetry

Hexaammineruthenium (III) [Ru(NH3)6]3+-Nafion®-isopropanol diluted films were spin coated on indium tin oxide (ITO)-coated glass substrates. The fabricated samples were used to determine the presence of lead and cadmium in solution using anodic strip-ping voltammetry (ASV). The calibration sensitivi...

Description
Summary:Hexaammineruthenium (III) [Ru(NH3)6]3+-Nafion®-isopropanol diluted films were spin coated on indium tin oxide (ITO)-coated glass substrates. The fabricated samples were used to determine the presence of lead and cadmium in solution using anodic strip-ping voltammetry (ASV). The calibration sensitivity of the electrodes for lead and cadmium were approximately equal. Detection limits of 5ppb and 4ppb were determined for lead and cadmium respectively. Real sampling tests with commercially available yellow water color yielded 0.7106 ppm of Pb with ASV. The result was verified with atomic absorption spectrometry (AAS) which yielded 0.6923ppm of Pb.
