“…This result demonstrates that the developed porous poly(2-oxazoline)-based polymers perform better than previously reported materials and can be effectively used for the selective removal of bisphenol S from water solutions. Finally, the q m values obtained for 2-naphthol are also higher than those reported for Fe3O4@polyaniline core–shell nanomaterials (28.7356 mg g –1 ), modified silica (71.9 mg g –1 ), and anion–cation organopalygorskite (33.65 mg g –1 ), indicating that the obtained porous polymers are effective adsorbents for the removal of 2-naphthol.…”

The development of porous poly(2-oxazoline)based polymers by a high internal phase emulsion procedure is reported. The porous polymers are obtained by cross-linking of short poly(2-oxazoline) chains possessing ester side chains using a triazabicyclodecene-catalyzed amidation reaction with diethylenetriamine as a cross-linker. The polymers are studied for adsorption of phenolic compounds, namely, 2,4-dichlorophenol, bisphenol S, and 2-naphthol as exemplary compounds. The influence of initial concentration, contact time, and pH on the adsorption process is investigated as well as the reusability of these porous polymers. The highest adsorption capacity is observed for adsorption of 2,4dichlorophenol, and it reached 260 mg g −1 . The adsorption kinetics for 2,4-dichlorophenol and bisphenol S are very fast as the maximum adsorption was reached after 30 and 15 min, respectively. Thermodynamic studies showed that the adsorption for 2,4-dichlorophenol and bisphenol S is entropy-driven, whereas the adsorption of 2-napthol is enthalpy-driven. The porous polymers are also used for quantification of the phenolic compounds by directly coupling them with ambient plasma mass spectrometry. The obtained limits of detection are two orders of magnitude lower than the ones obtained for analysis of the corresponding solutions, which include river samples. These results indicate that the porous poly(2-oxazoline)-based polymers possess a large potential for water purification as well as for the quantification of organic contaminants in water samples.

“…The reported adsorbents include carbons activated by KOH, HNO 3 H 3 PO 4 and ZnCl 2 , 17 olive wood biosorbents, 18 UiO-66-NH 2 , 19 glycidyl methacrylate graed cotton cellulose, 20 yellow bentonite, 21 XAD-4 resin, 22 activated carbon bers, 23 layered double hydroxides and their calcined products, 24 carbon nanospheres, 25 date seeds 26 and active carbon. 27 In recent years, ionic liquid-modied silicas (IL-silicas) as adsorbents have been widely used to remove Cu(II), Fe(III), Mn (II) and Ni(II), 28 Pb(II), [29][30][31] Cr(III,VI), [32][33][34] lanthanides and scandium ions, 35 oxymatrine, 36 bovine serum albumin, 37 racemic amino acids, 28 thiophenic sulfur compounds, 38 anionic dye, 39,40 dibenzothiophene 41 and phenolic compounds (4-chlorophenol, 42 polyphenols, 43 phenolic acids, 44 naphthols, 45 bisphenol A 46 and 2,4-DNP [47][48][49] ). To elucidate the relation between the structure of IL-silicas and their adsorption performance for phenolic compounds, a series of IL-silicas were designed by varying substituents, the functional groups of the imidazolium ring, counter ions and silane-coupling agents.…”

“…49 In order to overcome the negative effects of coexisting anions on the adsorptive removals of naphthols, a silica adsorbent was prepared through the co-modication of 1-vinyl-3octadecylimidazolium cations and p-styrenesulphonate anions on silica via click chemistry reaction. 45 In addition, imidazole, phenyl and hexadecyl were further co-immobilized onto silica via silane coupling reaction or thiol-ene click chemistry for bisphenol A adsorption from high salt aqueous solutions. 46 The review of literatures showed that one imidazolium-based ionic liquid was oen used to prepare the IL-silicas via silane coupling reaction.…”

“…1-Naphthol is an important raw material for the organic synthesis of pharmaceuticals, pesticides, and dyestuffs (4,5) and is also the major intermediate during the degradation of carbaryl (6), napropamide (7,8), and polycyclic aromatic hydrocarbons (PAHs) (9). Because of its common use, 1-naphthol is frequently detected in soil, water, and even the ocean (10,11).…”

1-Naphthol, a widely used raw material for organic synthesis, is also a well-known organic pollutant. Due to its high toxicity, 1-naphthol is rarely used by microorganisms as the sole carbon source for growth. In this study, catabolism of 1-naphthol by Sphingobium sp. strain B2 was found to be greatly enhanced by additional supplementation with primary carbon sources (e.g., glucose, maltose and sucrose), and 1-naphthol was even used as the carbon source for growth when strain B2 cells had been pre-induced by both 1-naphthol and glucose. A distinct two-component flavin-dependent monooxygenase NdcA1A2 was found to be responsible for the initial hydroxylation of 1-naphthol to 1,2-dihydroxynaphthalene, a more toxic compound. Transcriptional levels of ndcA1A2 genes were significantly up-regulated when strain B2 cells were cultured with both 1-naphthol and glucose as compared to cells cultured with sole 1-naphthol or glucose. Two transcriptional regulators, the activator NdcS and the inhibitor NdcR were found to play key roles in the synergistic regulation of the transcription of the 1-naphthol initial catabolic genes ndcA1A2. Importance Co-metabolism is a widely observed phenomenon, especially in the field of microbial catabolism of highly toxic xenobiotics. However, the mechanisms of co-metabolism are ambiguous and the roles of the obligately co-existing growth substrates remain largely unknown. In this study, we revealed that the roles of the co-existing primary carbon sources (e.g. glucose) in the enhanced catabolism of the toxic compound 1-naphthol in Sphingobium sp. strain B2 was not solely because they were used as growth substrates to support cell growth, but more importantly they acted as “co-inducers” to interact with two transcriptional regulators, the activator NdcS and the inhibitor NdcR, to synergistically regulate the transcription of the 1-naphthol initial catabolic genes ndcA1A2. Our findings provide new insights into the co-metabolic mechanism of highly toxic compounds in microorganisms.
