摘要: A direct method for silicon determination in milk samples by Electrothermal Atomic Absorption Spectrometry was developed. Palladium used as chemical modifier at a concentration of 610 mg L–1; with this modifier, stable up to 1800 °C. The precision and accuracy the were investigated. detection limit 16.2, 2.7 7.2 µg L–1 cows' milk, human infant formula, respectively. applied 17 formula samples, 13 12 samples.
