摘要 我国进口葡萄酒消费量逐年增加,其安全问题不容忽视。以来自8个不同国家的9种葡萄酒为样品,经消解后,采用原子吸收光谱法测定了其中铜(Cu)、铅(Pb)、铬(Cr)、镉(Cd)和锡(Sn)5种重金属元素的含量。该方法快速、准确、灵敏。葡萄酒样中5种元素的平均质量浓度分别为238.6,81.8,30.2,0.7和13.8μg/L,其中Cu元素的平均含量最高,Cd元素的平均含量最低。根据OIV标准,一款进口葡萄酒中铅元素的含量超标,其它元素的含量未超标。 Wine is a kind of fashion and healthy drink. Consumption of imported wine developed rapidly in domestic market, but more attention are paid on food safety. 9 kinds of different wine are collectedfrom eight countries, including America, Australia, Chile, Cyprus, Italy, France, New Zealand and Spain. A method for the determination of heavy metal (Pb, Cd, Cr, Sn, and Cu) in them by atomic absorption spectrometers (AAS) with high digestion is developed. The average mass concentrations of Cu, Pb, Cr, Cd, and Sn are 238.6, 81.8, 0.2, 0.7 and 13.8 μg/L, respectively. The average content of Cu element in wine is the highest; The average content of Cd element is the lowest. The method is rapid, accurate and sensitive. According to international standards Pb content in one wine samples exceed the standard level. And other elements were not exceeded. The experimental results provide a reliable experimental data for regulation of the Chinese imported wine consumption market.
