文摘
- •
Charge-transfer and hypercrosslinked phases retain polycyclic aromatic hydrocarbons.
- •
Shape selectivity and planarity selectivity on DNAP, 5HGN and HC-Tol are studied.
- •
The retention of PAHs is dependent on π–π interaction and inductive interaction.
- •
DNAP has the largest planarity selectivity. 5HGN has the strongest π–π interaction.
- •
Thermodynamics shows no change in retention mechanism for PAHs over 20–60 °C.
