Abstract
Изобретение относитс к аналил и- ческой химии, а именно к способам определени содержани хлорид-ионов в жидких средах, и может быть использовано в сельском хоз йстве, пи1 1евой промышленности и медицине с пелью удетаевлени анализа за счет исключени солей серебра. Дл этого к анализируемой пробе, помещенной в тр.рмо- изолированную пенопластом кювету,добавл ют Г мл насьпценного раствора сульфата меди и одновременно регистрируют температуру пробы термодатчиком ТФ-3, чувствительный элемент которого экранирован алюминиевой фольгой . Через 5 мин после введени в пробу насыщенного раствора сульфата медн измер ют теьшсрптуру рлстпора. По калибровочноьгу графику и экспериментально определенной величине повышени температуры раствора определ ют .содержание хлорид-ионов в пробе. The invention relates to analytical chemistry, in particular, to methods for determining the content of chloride ions in liquid media, and can be used in agriculture, industry and medicine with an analysis of the effect by eliminating silver salts. For this purpose, to the analyzed sample, placed in a cuvette insulated with foam plastic, is added G ml of a fine copper sulphate solution and simultaneously record the temperature of the sample with a TF-3 thermal sensor, the sensitive element of which is shielded with aluminum foil. Five minutes after the introduction of a saturated solution of copper sulphate into the sample, the temperature of the rstpor was measured. According to the calibration curve and the experimentally determined value of the increase in the temperature of the solution, the content of chloride ions in the sample is determined.

Изобретение птиогитс к аналитической химии, именно к способам оп- ределпни содержани хлорид-иоттов в жидких средах, и может быть игполь- зовано в сельском хоз йстве, пищевой промъпчленности и медицине.The invention of analytical chemistry, specifically to methods for determining the content of chloride in liquid media, can be used in agriculture, food industry and medicine.
Цель изобретени - удешевление анализа за счет исключени солей се- ребра.The purpose of the invention is to reduce the cost of analysis by eliminating salts of silver.
Пример. К анализируемой пробе объемом 1 МП, помещенной н термоизолированную пенопластом кювету, добавл ют 1 мл насыщенного раствора сульфата меди и одновременно регистрируют температуру пробы термодатчиком ТФ-3, чувствительный элемент ко- торого экранирован алюминиевой фольгой . Через 5 мин после введени в пробу насьпиенного раствора сульфата меди измер ют температуру раствора,Example. To the analyzed sample with a volume of 1 MP, placed on a cuvette insulated with foam, add 1 ml of a saturated solution of copper sulfate and simultaneously record the temperature of the sample with a TF-3 thermal sensor, the sensitive element of which is shielded with aluminum foil. Five minutes after the injection of the copper sulfate solution into the sample, the temperature of the solution was measured.
Температур исходной пробы , а температура р створа noche введени насьптенного раствора сульфата меди 32,5°С. По калибровочному графи ку наход т содержание хлорид-ионов в пробе, которое составл ет 0,14%,The temperature of the original sample, and the temperature of the nocherive solution, the introduction of a copper sulphate solution, was 32.5 ° C. The calibration graph shows the chloride ion content in the sample, which is 0.14%,

Экзотермический эффект последней реакции пропорционален содержанию хлорид-ионов в анализируемой пробе.The exothermic effect of the last reaction is proportional to the content of chloride ions in the sample being analyzed.
Анализ по предлагаемому способу проводитс без использовани солей серебра, что значительно уменьшает затраты на проведение анализа.The analysis of the proposed method is carried out without the use of silver salts, which significantly reduces the cost of the analysis.
