“…The solutions were stirred constantly until the equilibrium was reached. The equilibrium concentration, C e (mmol L −1 ), was determined and the equilibrium adsorption capacity, q e (mmol g −1 ), was calculated [31]. Kinetic adsorption studies of phenol, p-NPh and p-cresol were performed at the temperature of 293, 313 and 333 K, respectively, by analyzing the adsorption capacity q t (mmol g −1 ) vs. the initial concentration of 1 mmol L −1 at different time intervals until the adsorption equilibrium was reached.…”

The mechanism of thermal degradation of poly(furfuryl alcohol) (PFA) deposited on the MCM-48 mesoporous silica was studied. The behaviour of the thin PFA film homogeneously dispersed on the silica surface (the material with the real PFA/MCM-48 mass ratio of 0.06) was compared to that of the 3D structure of PFA completely filling the MCM-48 channels (the material with the real PFA/MCM-48 mass ratio of 1.02). The progress of decomposition was controlled by thermogravimetry accompanied by infrared spectroscopy providing information on the composition of gaseous products evolved during the sample degradation. The thermal treatment of PFA/ MCM-48 composites at various temperatures in the range of 523-1323 K enabled us to synthesize two series of PFAderived carbon adsorbents: (1) containing the degraded PFA film supported on the mesoporous silica and (2) CMK-1 type carbon replicas, which were obtained by leaching of SiO 2 from the PFA/MCM-48 composite after the previous pyrolysis. The structural and textural properties of these materials were determined by powder X-ray diffraction, DRIFT spectroscopy and low-temperature nitrogen adsorption. Furthermore, the samples were tested as adsorbents of different volatile organic compounds (VOCs). The PFA/MCM-48 materials showed the high adsorption capacity only in the removal of polar molecules, whereas CMK-1 was effective in the elimination of linear alkanes and aromatic VOCs as well.

“…Hence, they are ubiquitous in the soil environment and tend to accumulate in the top soil mainly around industrial and urban activities (Johnsen and Karlson 2007). Persistence of high molecular weight (HMW) PAHs in the environment mainly due to dense clouds of p-electrons on both sides of the ring structures is a serious environmental concern which needs to be addressed for ensuring human health (Long et al 2008).…”

An investigation was carried out to compare the ability of two bacteria Pseudomonas aeruginosa PSA5 and Rhodococcus sp. NJ2 isolated from petroleum sludge for degradation of benzo(a)pyrene [B(a)P], a HMW PAH compound in MSM. During 25 days of incubation, 50 ppm B(a)P was degraded by 88 and 47 % by P. aeruginosa PSA5 and Rhodococcus sp. NJ2, respectively. Besides, involvement of different catabolic enzymes, that is, salicylate hydroxylase, 2-carboxybenzaldehyde dehydrogenase, catechol 1,2-dioxygenase and catechol 2,3-dioxygenase, was also examined to identify their differential role in B(a)P degradation. Among these enzymes, the highest induction of 2-carboxybenzaldehyde dehydrogenase (773.5 nmol mg -1 protein) was recorded in P. aeruginosa PSA5, while salicylate hydroxylase was highly expressed (839.6 nmol mg -1 protein) in Rhodococcus sp. NJ2. Both the bacteria were found biosurfactant (glycolipid) producing, and role of biosurfactant in PAH degradation was also ascertained by reduced surface tension, higher emulsification index and increased cell surface hydrophobicity.
