A method is described for direct electrothermal atomic absorption spectrometric (ETAAS) determination of cadmium in untreated samples of wine. Pyrolytic graphite tubes and graphite tubes with standard L'vov pyrolytic platforms were tested as atomizers. The detection limit achieved was 0.08 microg L(-1) Cd in wine. The relative standard deviation for the concentration range from 0.2 to 10 microg L(-1) Cd ranged from 1 to 7%. The accuracy of the method was confirmed by comparing the current results with those found for wet digested wine samples and by the analysis of spiked samples. By applying the proposed method it was found that the cadmium concentration in Macedonian wines ranges from 0.10 to 0.90 microg L(-1).
描述了一种直接电热原子吸收光谱法（ETAAS）测定未处理葡萄酒样品中镉的方法。测试了热解石墨管和带有标准L'vov热解平台的石墨管作为原子化器。葡萄酒中镉的检测限为0.08 μg L⁻¹。镉浓度在0.2至10 μg L⁻¹范围内的相对标准偏差为1%至7%。通过将当前结果与湿消解葡萄酒样品的结果进行比较以及对加标样品的分析，证实了该方法的准确性。应用所提出的方法发现，马其顿葡萄酒中的镉浓度范围为0.10至0.90 μg L⁻¹。
