Title: Ion chromatographic determination of acidity
Author: De Borba, Brian M.
Abstract: The practice of acidity measurements by volumetric titration has remained unchanged for over two centuries . Though optochemical methods may exist for measuring H* concentrations , none of these methods are capable of measuring large concentration ranges or are able to determine the concentration of multiple cations , in addition to H* (i .e . , K+ , NH4+ , etc . ) , which may be of interest to the analytical chemist . The present work presents a new approach to acidity measurements based on cation exchange chromatography . A sulfonated styrenedlvinylbenzene based stationary phase is used to separate hydrogen ion from other monovalent cations . In addition , several factors that govern the direct determination of strong and weak acids were examined .
