      abstract     = {The effect of organic carbon (OC) and mineral surface on
                      the sorption of polycyclic aromatic hydrocarbon (PAH) pyrene
                      molecule to four Yangtze River sediments was investigated by
                      sorption batch techniques using fluorescence spectroscopy.
                      Pyrene sorption to the mineral fraction was estimated with
                      model sorbent illite, the main clay mineral in Yangtze
                      sediment. The Freundlich model fitted sorption to illite and
                      to sediments was normalized to the specific surface area
                      (SSA). Comparison of the SSA-normalized sorption capacities
                      of illite and sediments suggests a negligible contribution
                      of the pyrene sorption to the mineral fraction. In addition,
                      composite models, such as the linear Langmuir model (LLM)
                      and the linear Polanyi-Dubinin-Manes model (LPDMM) were
                      applied for fitting the sorption of pyrene to the pristine
                      sediments. The application of composite models allows
                      assessing the partition of pyrene into amorphous organic
                      carbon (AOC) and the adsorption in the porous structure of
                      black carbon (BC). The modelling results indicate that the
                      pyrene adsorption to the minor BC components $(<0.2\%)$ is
                      more effective than the partition to AOC $(0.5-1.3\%).$
                      Besides the pristine sediments, sediments preheated at 375
                      degrees C were also studied, in which the AOC fraction was
                      removed during the preheating treatment. The modelling
                      results with LPDMM and Polanyi-Dubinin-Manes model (PDMM)
                      indicate a similar adsorption capacity of BC in pristine and
                      preheated sediments, respectively. The low AOC
                      concentrations in sediments do not diminish the BC micropore
                      filling with pyrene. Simulation of pyrene distribution in
                      the investigated Yangtze River sediments support the
                      importance of the BC fraction in the PAH immobilization
                      under environmental conditions.},
