    Abstract: Single-walled carbon nanotubes (SWCNTs), used as the stationary phase materials, were packed into the HPLC column by the downward slurry method. Retention factors of 18 common organic compounds in acetonitrile phase on SWCNTs column were measured and used to investigate the interaction between SWCNTs and organic compounds. The results show that the interactions between SWCNTs and organic compounds in acetonitrile phase are related to the number and types of functional groups and the number of hetero-atoms. The interactions between SWCNTs and organic compounds were characterized quantitatively using the linear solvation energy relationships (LSER). The obtained LSER model has a goodness of fit (R2=0.844) and robustness (QLOO2=0.768). The results demonstrate that the interaction with π-/n- electrons and cavity/dispersion interactions are the main factors that influence the interactions between SWCNTs and organic compounds.
