摘　　要：通过原子分光光度计测定了葡萄酒及其蒸馏酒中的铜含量,数据显示,所有原酒及玻璃器皿蒸馏的酒样中铜含量都较低,符合国家标准,而紫铜壶蒸馏获得酒样中的铜含量较高,其中一个酒样超过国家标准。研究结果显示,葡萄蒸馏酒中铜含量主要来源于紫铜蒸馏器,使用紫铜蒸馏器进行蒸馏更应该注意分析和控制铜含量才能生产合格的蒸馏酒或白兰地。Cu content in grape wine and brandy was determined by flame absorption spectrometry in the experiment.The data showed that,Cu content in wine and brandy distilled in glassware was comparatively low,and met the national standards.However,Cu content in brandy distilled in purple copper distiller was high(one sample exceeded national standards).The research results also revealed that Cu in brandy mainly came from purple copper distiller.Accordingly,it was important to analyze and control Cu content in order to produce eligible brandy when purple copper distiller was used.
