摘要
利用乙醇-水缔合体系产生的吸收峰强度与乙醇含量成比例的关系,建立了测定乙醇的新方法。乙醇体积浓度在15%～85%范围内,相关系数0.9983,变异系数0.186%。回收范围在99.52%～104.87%。该方法操作简便、快速,将其应用于白酒中乙醇含量的测定,所得结果与比重法相近。(丹妮)
The absorption peak intensity of alcohol-aqua association system was in proportion to alcohol content.Accordingly,new method to determine alcohol content was discovered.The volume concentration of alcohol was in the range of15%～85%,the correla-tion coefficient and variation coefficient were0.9983and0.186%respectively.The recovery range was between99.52%～104.87%.This method had superiorities of simple operation and rapid determination.Its application in the determination of alcohol content had almost the same results as hydrometer method.(Tran.by YUE Yang)
