Abstract

Linear Solvation Energy Relationships To Explain Interactions Responsible for Solute Adsorption onto a Polar Polymeric Sorbent

“…Similar conclusions have been reported by Ageev et al . and Belyakova et al., who performed chromatographic studies with a polar copolymeric sorbent, a hexane eluent, and a series of monosubstituted, non-HBD benzene derivatives. The chromatographic capacity factors observed in their studies could be correlated to the solute's dipole moment.…”

“…Included in Figure 4 are π* values recently reported by Laurence et al 32 The correlation in Figure 4 suggests that dipolar or inductive mechanisms are responsible for the adsorption of monosubstituted benzenes or heterocyclics that have a single polar region but lack HBD acidity. Similar conclusions have been reported by Ageev et al 33 and Belyakova et al, 34 who performed chromatographic studies with a polar copolymeric sorbent, a hexane eluent, and a series of monosubstituted, non-HBD benzene derivatives. The chromatographic capacity factors observed in their studies could be correlated to the solute's dipole moment.…”
