Abstract
Since Saint-Flour and Papirer first introduced Gutmann's acceptor number and donor number parameters into the inverse gas chromatography (IGC) field in 1982, IGC has become an important technology for the measurement of surface Lewis acid-base properties of solid materials. However, introducing new roles of Lewis acid-base parameters, especially using them to predict material properties rather than just explain material properties, is an important aspect in developing IGC technology. In this paper, we first introduce the Schultz and Abraham methods for measurement of acid-base properties and discuss the traditional role of acid-base parameters. Then, we present a relation between the ratio of acid-base constants, Ka/Kb, and triboelectric charge density of some polymers to prove the possible new application field of IGC.
