Изобретение относится к аналитической химии и может быть использовано для определения количества содержащихся в воде органических примесей. Изобретение направлено на сокращение длительности и трудности процесса, уменьшение количества операции. Способ предполагает окисление и перемешивание анализируемой пробы подачей озоно-воздушной смеси в потоке, циркулирующем в замкнутом трубчатом контуре, который содержит рабочий и U-образный холостой участки. На рабочем участке контура формируют восходящий поток анализируемой пробы, для чего в озоно-воздушную смесь подают в нижнюю его точку. Отвод исходящей струи газов осуществляют через открытый канал, располагаемый в верхней точке рабочего участка. Контроль достижения заданного порога избытка озона в пробе после окисления органики ведут датчиком в виде пары платиновых электродов, подключенных к источнику постоянного тока, электронной схеме усиления и регистрации сигнала. Датчик располагают в циркулирующем потоке пробы на холостом участке контура. Рабочий участок может быть выполнен спиральным, а открытый патрубок - сечением, превышающем сечение рабочего участка. Заполнение замкнутого контура пробой ведут через воронку и подающий патрубок, соединенный с холостым участком, при этом данный патрубок и подающий патрубок для озоно-воздушной смеси присоединяют к разным ветвям U-образного холостого участка замкнутого контура.The invention relates to analytical chemistry and can be used to determine the amount of organic impurities contained in water. The invention is aimed at reducing the duration and difficulty of the process, reducing the number of operations. The method involves the oxidation and mixing of the analyzed sample by supplying the ozone-air mixture in a stream circulating in a closed tubular loop, which contains the working and U-shaped idle sections. On the working section of the contour, an upward flow of the analyzed sample is formed, for which an ozone-air mixture is fed to its lower point. The discharge of the outgoing gas stream is carried out through an open channel located at the top of the work area. Monitoring the achievement of a given threshold of excess ozone in the sample after the oxidation of organic matter is carried out by the sensor in the form of a pair of platinum electrodes connected to a DC source, an electronic gain circuit and a signal recording. The sensor is placed in the circulating sample stream in the idle portion of the circuit. The working section can be made spiral, and the open pipe can be made with a cross section exceeding the section of the working section. The filling of the closed circuit breakdown lead through the funnel and the feed pipe connected to the idle section, while this pipe and the feeding pipe for the ozone-air mixture is attached to different branches of the U-shaped idle section of the closed loop.
