摘　　要：建立微波消解-电感耦合等离子质谱检测葡萄酒中重金属的方法,并用该方法对葡萄酒中Fe、Zn、Cu、Pb、As、Cd和Cr等7种重金属进行检测。结果发现该方法具有较好的准确性和精密度,通过加标回收测定,7种重金属回收率在95.2%～101.2%。同时通过对6个不同厂家生产的葡萄酒中7种重金属元素进行测定,发现葡萄酒中Fe、Zn、Cu的含量相对较高,但均未超出国家允许的限量标准。A method for determination of heavy metal（Fe,Zn,Cu,Pb,As,Cd and Cr）in wine by inductively coupled plasma-mass spectrometry（ICP-MS）with microwave digestion was developed.When using it to determine the heavy metal of wine,the results showed that this method was high accuracy and precision.In the recovery experiment controlled by adding standard substance,the recovery of these seven elements was in the range of 95.2%-101.2%.In addition,the results showed that the wine contain more Fe,Zn and Cu.However,all the data showed that the wine meets the national hygiene standards.
