对于糖的测定,目前国内外均采用斐林法、碘量法、分光光度法及离子选择电极法等。本文研究了用原子吸收法测定被糖还原的 Cu_2O 的量间接测定还原糖含量的实验条件,并用于葡萄糖中间体、成品、桔子汁、蔬菜、酱、醋、蜂蜜及人体血液等样品中还原糖含量的测定。其线性范围0.05—3mg,回收率98—101%,变动系数1%。本工作是在 pH约为11的碱性介质中,以还原糖将柠檬酸铜络合物
For the determination of sugar, both at home and abroad are used Feilin method, iodometry, spectrophotometry and ion-selective electrode method. In this paper, the experimental conditions for the determination of reducing sugar content by sugar reduction Cu 2 O by indirect atomic absorption spectrometry were studied and used for reducing sugar in glucose intermediate, finished product, orange juice, vegetable, sauce, vinegar, honey and human blood Determination of content. The linear range of 0.05-3mg, recovery rate of 98-101%, coefficient of variation of 1%. This work is in a pH of about 11 alkaline medium, reducing sugar will be copper citrate complex
