METHOD FOR DETERMINATION OF REDUCING SUBSTANCES CONTENT IN SUGAR-CONTAINING MEDIA

摘要

FIELD: chemistry. ^ SUBSTANCE: present invention refers to determination of reducing substances in water solutions at various natures of analysed media. The method is carried out by oxidation of reducing substances with copper (II) compounds in alkali media in the excess of oxidiser, reducing substances concentration is determined by decrease of optical density at 670 nm. ^ EFFECT: providing of high accuracy and labour input of the analysis. ^ 2 tbl
