Abstract
Изобретение может быть использовано в отрасл х промышленности. производ щих или потребл ющих уксусную кислоту. Цель изобретени - обеспечение раздельного определени концентраций Jj и J -и улучшение условий труда. Поставленна цель достигаетс тем, что концентраци йода в- уксусной кислоте определ етс пу тем измерени потенциала йод-селективного электрода сначала в исходном растворе уксусной кислоты, где диссоциаци молекул рного йода равна 1/2, а затем в уксусной кислоте, в которую добавлена щелочь до рН 3, где диссоциаци молекул рного йода равна 1. В результате обеспечиваетс раздельное определение J и J и исключаетс применение мышь ка. , 1 ил. о фThe invention can be used in industry. producing or consuming acetic acid. The purpose of the invention is to provide a separate determination of the concentrations Jj and J - and the improvement of working conditions. The goal is achieved by the fact that the concentration of iodine in acetic acid is determined by measuring the potential of the iodine-selective electrode first in the stock solution of acetic acid, where the dissociation of molecular iodine is 1/2, and then in acetic acid, to which alkali is added pH 3, where the dissociation of molecular iodine is equal to 1. As a result, a separate determination of J and J is provided and the use of a mouse is excluded. , 1 Il. about f
