Cadmium atomization on W, Ru, and W + Ru modifier-coated platforms and pyrolytic graphite-coated platforms with and without W, Ru, W + Ru, and Pd + Mg modifier solutions was obtained by electrothermal atomic absorption spectrometry (ETAAS). Surface morphologies of coated and uncoated platforms were investigated by scanning electron microscopy to show the evidence of coating. Pyrolysis, peak appearance, and atomization temperatures of Cd with or without coated platforms and modifier solutions were obtained. The activation energies and frequency factors of Cd atomization were found and evaluated. Results obtained were comprehensively compared with each other and published values.
