摘要：

The basicity of alkali-exchanged zeolites has been characterized by chloroform adsorption using FTIR spectroscopy. The chloroform is adsorbed on the basic oxygen site through its hydrogen atom, while a weak interaction also exists between the adjacent cation and the chlorine atom of chloroform. The charge on the oxygen atoms (basic sites) was calculated using the electronegativity equivalence method. The CH stretching frequency of chloroform adsorbed on basic sites is well correlated with this oxygen charge.
