Spin Coated Hexaammineruthenium(III)/Nafion/ITO electrodes for the Determination of Lead(II) and Cadmium(II) via Anodic Stripping Voltammetry

Abstract

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.

Determination of Lead(II) and Cadmium(II) in Selected Commercially Available Water‐Based Paints of Ethiopia by Anodic Stripping Voltammetry Using a Bismuth‐Modified Glassy Carbon Electrode

“…Water‐based paints samples of four colors (Green 160, Red 225, Violet 224, and White 117) were purchased from three different paint companies (DH‐Geda paint factory, Nifas silk paint factory, and Tsehay paint factory), a total of twelve samples, in Addis Ababa, Ethiopia. The samples were prepared using a procedure reported elsewhere with minor modifications [16–17] . A sample of paint was spread on the surface of a clean glass slide and air dried for 24 h. Then further dried in the oven for 12 h at 120 °C.…”
