Method of measuring carbon dioxide concentration in the solution

摘要

PROBLEM TO BE SOLVED: To provide a method and device for simply and quickly measuring the carbon dioxide gas concentration in a solution in a site.;SOLUTION: This method is provided to measure the carbon dioxide gas concentration in a solution with a carbon dioxide gas concentration of 100 mg/l or higher and a pH of 6 or lower. The method includes a process for putting a sample solution in a container by 1 to 50% of the container capacity and sealing the container, a process of shaking the container, a process of measuring the carbon dioxide gas concentration in gas phase in the container after shaking, and a process for converting the concentration in the gas phase to the carbon dioxide gas concentration in the solution.;COPYRIGHT: (C)2004,JPO
