摘要
Two different anthryl-modified silica packings were investigated for the separation of PAHs and nitro-PAHs. Plots of k′ versus mobile phase composition show distinct selectivity both with acetonitrile/water and with methanol/water. PAHs are separated by π-π-interactions, whereas the corresponding nitrosubstituted compounds are longer retained on both stationary phases due to charge-transfer interactions being possible. © 1990 Friedr.
