摘要：

The distribution of n-alkylammonium ions on a Whatman ODS-2 reversed-phase column was investigated. It was found that only about 24% of the retained n-alkylammonium ions act as ion-pairing reagents on the column surface. Approximately 76% of the n-alkylammonium ions are electrostatically interacting with the deprotonated surface silanols.
