Abstract
OBJECTIVE: Consider the use of calcimeter “Fann” to analyze the absorbing substance for the content of carbon dioxide.
MATERIALS AND METHODS: There was an analysis of the absorbing substance for the content of carbon dioxide by two methods. Their working principle is based on decomposing acid effect on chemical absorber, resulting in a chemical reaction and producing carbon dioxide.
RESULTS: Pressure, generated in the reaction process in a closed reactor, is directly proportional to the carbonate content in the sample. The use of calcimeter “Fann” allows to determine the content of carbon dioxide in chemical absorber fast and with high degree of accuracy
