Measuring method and the measurement equipment of carbon dioxide concentration which dissolves in the seawater

摘要

(57) Abstract PH measurement is done manner and the device namely CO₂ concentration in order to measure the CO₂ content which dissolves in the seawater CO₂ concentration of that seawater by the chrometric analysis of the solution which makes equal, wavelength of absorption peak of basic configuration of the dye (measurement is run with _M) property and the, the wavelength where dye is not absorbed (_B) with acquisition measurement is done and is close to the isosbestic point of the, dye the wavelength which (_I) with acquisition absorbency measurement is done. The device although measurement is run in the output of the measurement electrolysis cell and the electrolysis cell where the solution of the coloration indicator entering has entered, with this manner consists of with the means which consecutively put the filter on the light beam at necessary respective wavelength.
