葡萄酒中微量元素丰富,且含量易受到产地、酿造、加工等因素的影响。某些元素的过量存在,如铁、锰和铜等,不仅会降低葡萄酒的品质,还会对健康造成危害。常见的元素分析方法需对样品进行前处理,以去除有机基体的干扰,如湿法和干法消化。但样品的前处理,通常繁琐,易造成元素的污染或损失[1,2]。该文采用电感耦合等离子体光谱法(ICP-OES)直接测定葡萄酒中Cr,Cu,Fe,Mg,Mn,Zn,通过增大RF功 Trace elements rich in wine, and the content is susceptible to origin, brewing, processing and other factors. Excessive presence of certain elements, such as iron, manganese and copper, will not only reduce the quality of the wine, but also harm the health. Common elemental analysis methods require sample pretreatment to remove interference from organic substrates such as wet and dry digestion. However, the sample pretreatment, usually cumbersome, easily lead to the pollution or loss of elements [1,2]. In this paper, direct determination of Cr, Cu, Fe, Mg, Mn, Zn in wine by inductively coupled plasma spectrometry (ICP-OES)
