“…The choice of adsorbents is determined by several factors such as collection efficiency, capacity of adsorbent (breakthrough volume), the adsorbent chemical stability during sampling, storage, and extraction, low blank levels, low affinity for water vapor, and high facile recovery of adsorbed vapors. This last factor has led to performing PAH sampling with adsorbents such as XAD-2, − XAD-4, , Tenax, , polyurethane foam (PUF), , fluorisil, alumina, Bondapak C18 on Porasil, Chromosorb 102, SepPak-C18, Graphpac GC, and Graphtrap GC 17 instead of carbonaceous compounds. The carbonaceous compounds are characterized by a high PAH retention capacity, due to their high specific surface, but they have a low efficiency in PAH desorption .…”

This is the first time that the adsorption of phenanthrene (Phe) for hot gas emissions cleaning from combustion has been studied. For this goal, the adsorption capacity of 10 active carbons with different origins and a wide range of textural characteristics has been assessed for Phe removal from hot gas emissions. The study was carried out at laboratory scale and the main aim has been to test the Phe adsorption capacities by the porous materials at the ranges that Phe could be emitted from new energy systems generation. The protocol followed in this work was the following: first, to check the influence of the bed mass on the Phe adsorption capacity, and second, once it was shown that the bed mass is not relevant for the studied Phe concentration range, the adsorption capacity of the 10 adsorbents was analyzed. The CA-3 adsorbent was selected to check the inlet concentration at three different temperatures, 125, 150, and 175 °C, within the range of atmospheric emissions from the power stations. The results obtained show that there is a good correlation between the Phe adsorption capacity and the total micropore volume calculated with the Dubinin-Radushkevich equation for the N 2 isotherm data. No relationship was found between Phe adsorption capacity and mesopore volume calculated by BJH method. Besides, no relationship was found between chemical surface (CO and CO 2 groups desorbed on thermal program desorption (TPD)) and adsorption capacity.

“…For the sampling of PAH the sorbents used have included Tenax, XAD-2, polyurethane foam (PUF), Florisil, Chromosorb 102 38 and Bondapak-Cis on Porasil. 34 The use of charcoal tubes for the collection of organic vapours was widespread and they have been used to collect three-ring PAH but the release of PAH from charcoal is usually difficult. 88 Tenax GC was utilized as a sorbent in source sampling of combustion sources.…”

“…Several studies have been reported in which HiVol samplers with a PUF plug as a back-up sorbent have been used in sampling for ambient PAH. 34 The collection efficiencies of sorbents have not been sys-tematically investigated in order to define and quantify relationships between parameters such as flow rates, linear face velocities, retention volume, effects of temperature and nature of target compound. However, several studies have reported some aspect of the collection efficiencies of some sorbents.…”

“…It was assumed that the collection efficiency of PUF was adequate. Lindgren et al 34 compared the retention capacities of two 27-mm diameter, 38-mm thick plugs (PUF), Bondapak-Cis (on Porasil B 37-75 jim) and GC Bondapak-C18 (on Porasil C 120-150 mesh, two 5-7 mm thick layers separated by glass wool). For equal air volumes, the Bondapak-Cis consistently absorbed larger amounts of PAH than PUF plugs.…”
