摘要：
 2-Amino-1-cyclopentene-1-dithiocarboxylic acid silica gel (ACDA-SG) loaded with Ag(I) or Pd(II) ions has been examined for the group fractionation of polycyclic aromatic sulfur heterocycles (PASH) from polycyclic aromatic hydrocarbons (PAH) via ligand-exchange chromatography in the normal phase mode. It is shown that metal loading has a great impact on the selectivity of ACDA-SG for PASH and PAH. Pd(II) loaded ACDA-SG proved to be suitable for the group isolation of PASH from the aromatic fractions of petroleum mixtures (number of condensed rings?3).
