abstract = {Sorption of pyrene and phenanthrene to model (illite and
charcoal) and natural (Yangtze sediment) geosorbents were
investigated by batch techniques using fluorescence
spectroscopy. A higher adsorption of phenanthrene was
observed with all sorbents, which is related to the better
accessibility of smaller molecules to micropores in the
molecular sieve sorbents. In addition, pyrene sorption in
binary-solute systems with a constant initial concentration
of phenanthrene (0.1 μmol L(-1) or 2 μmol L(-1)) was
studied. A 0.1 μmol L(-1) concentration of phenanthrene
causes no competitive effect on the pyrene sorption. A 2
μmol L(-1) concentration of phenanthrene significantly
suppresses the sorption of pyrene, especially in the low
concentration range; nonlinearity of the pyrene sorption
isotherms thus decreases. The competitive effect of 2 μmol
L(-1) phenanthrene on the pyrene sorption is overestimated
by the ideal adsorbed solution theory (IAST) using the
fitted single sorption results of both solutes. An
adjustment of the IAST application by taking into account
the molecular sieve effect is proposed, which notably
improves the IAST prediction for the competitive effect.},
