Continuous acid-free measurements of total alkalinity

Research output: Contribution to journal › Article › peer-review

Abstract

A system and method for the substantially continuous measurement of the total alkalinity of a sample solution, which includes, equilibrating a sample solution and a gas at a chosen CO2 fugacity across a gas permeable membrane, measuring the equilibrium pH of the equilibrated solution in an optical cell using a spectrophotometric pH indicator and calculating the total alkalinity of the solution from the equilibrium pH measurement of the solution and a known partial pressure of CO2.
