Abstract
The regularity of retention of unsubstituted and methylsubstituted pol yphenyls and condensed polycyclic aromatic hydrocarbons in normal-phas e (NP) HPLC with a non-polar mobile phase (n-hexane) on hydroxylated s ilica has been studied. It was shown that chromatographic retention of aromatic hydrocarbons depends not only on number of aromatic rings an d methyl groups in a molecule, but also on a nature of the bond betwee n the aromatic rings of polyphenyls and condensed polycyclic aromatic hydrocarbons. A structure - retention relationship has been proposed f or description of the retention regularity of the aromatic hydrocarbon s studied.
