SIMPLIFIED SAMPLER FOR MEASURING CONCENTRATION OF CARBON DIOXIDE USING TURBIDITY CHANGE AND METHOD FOR MEASURING CONCENTRATION OF CARBON DIOXIDE USING SAME

摘要

The present invention relates to a method for simply measuring concentration of carbon dioxide in the air using change of turbidity and a simplified sampler for the same. When a liquid barium hydroxide (Ba(OH)2) solution reacts with carbon dioxide gas by natural concentration diffusion, and forcible injection, BaCO3 granular precipitate is generated. The amount of the generated precipitate is measured using a turbidimeter as a turbidity value. Using the correlation equation between the measured turbidity value and concentration of carbon dioxide, the concentration of carbon dioxide in the target gas can be simply measured. The simplified sampler is able to collect carbon dioxide gas in the air.;COPYRIGHT KIPO 2014
