[More] The photocatalytic degradation of a series of six acid dyes (Direct Red 80, Direct Red 81, Direct Red 23, Direct Violet 51, Direct Yellow 27, and Direct Yellow 50) has been tested compared in terms of color removal, mineralization, and toxicity (Lactuca sativa L. test) after photocatalysis on immobilized titanium dioxide. The dyes were examined at their natural pH and after hydrolysis at pH 12. Results show that hydrolysis decreases strongly the efficiency of color removal, that full mineralization takes much longer reaction time than color removal, and that toxicity is only very partially reduced. Some structural parameters, related to the structure and the topology of the dye molecules, could be correlated with the apparent color removal rates at natural pH.

pi(+)-pi Interactions between (Hetero)aromatic Amine Cations and the Graphitic Surfaces of Pyrogenic Carbonaceous Materials

Authors: Xiao, F; Pignatello, JJ (2015) Environmental Science and Technology 49:906-914. HERO ID: 3019877

[More] Many organic compounds of environmental concern contain amine groups that are positively charged at environmental pH. Here we present evidence that (hetero)aromatic amine cations can act as p acceptors in forming pi(+)-pi electron donoracceptor (EDA) interactions with the p electron-rich, polyaromatic surface of pyrogenic carbonaceous materials (PCMs) (i.e., biochar, black carbon, and graphene). The pi(+)-pi EDA interactions combine a cation-p force with a pp EDA force resulting from charge polarization of the rings quadrupole. Adsorption on a biochar and reference adsorbent graphite was conducted of triazine herbicides, substituted anilines, heterocyclic aromatic amines, and other amines whose charge is insulated from the aromatic ring. When normalized for the hydrophobic effect, the adsorption increased with decreasing pH as the amines became ionized, even on graphite that had no significant fixed or variable charge. The cationic p acceptor (quinolinium ion) was competitively displaced more effectively by the p acceptor 2,4-dinitrobenzene than by the p donor naphthalene. The maximum electrostatic potential of organocations computed with density functional theory was found to be a strong predictor of the pi(+)-pi EDA interaction. The pi(+)-pi EDA interaction was disfavored by electropositive alkyl substituents and by charge delocalization into additional rings. Amines whose charge was insulated from the ring fell far out of the correlation (more positive free energy of adsorption). Identifying and characterizing this novel pi(+)-pi EDA interaction on PCMs will help in predicting the fate of organocations in both natural and engineered systems.

[More] Global concern about pharmaceutical and endocrine disrupting compounds in water resources is at its most intense due to their adverse effects on human health and environmental sustainability. Polydopamine-coated magnetic nanoparticles (MNPs@PDA) and polypyrrole-coated magnetic nanoparticles (MNPs@PPy) were successfully synthesized with strong magnetic attraction for easy separation. Their binding efficiencies with bisphenol A (BPA), metformin (MF), naphthalene acetic acid (NAA), phenformin (PF), quinine sulfate (QS), and triclosan (TC) in water were determined using capillary electrophoresis with UV detection. At a concentration of 200mgmL(-1), the binding efficiencies of MNPs@PPy were found to be 99 +/- 1% BPA, 34 +/- 4% MF, 39 +/- 6% NAA, 99 +/- 1% PF, 98 +/- 2% QS, and 99 +/- 1% TC, whereas MNPs@PDA afforded 65 +/- 5% BPA, 14 +/- 6% MF, 21 +/- 4% NAA, 99 +/- 1% PF, 94 +/- 2% QS, and 92 +/- 3% TC. Hence, both MNPs@PDA and MNPs@PPy have a high capacity for efficient removal of aromatic compounds from water.

[More] The first hybrid base constructed from 1,8-bis(dimethylamino)naphthalene (proton sponge or DMAN) and glycine, N-methyl-N-(8-dimethylamino-1-naphthyl)aminoacetic acid, was synthesised in high yield and its hydrobromide was structurally characterised and used to determine the acid-base properties via potentiometric titration. It was found that the basic strength of the DMAN-glycine base (pKa = 11.57, H2O) is on the level of amidine amino acids like arginine and creatine and its structure, zwitterionic vs. neutral, based on the spectroscopic (IR, NMR, mass) and theoretical (DFT) approaches has a strong preference to the zwitterionic form. Unlike glycine, the DMAN-glycine zwitterion is N-chiral and is hydrolytically cleaved with the loss of glycolic acid on heating in DMSO. This reaction together with the mild decarboxylative conversion of proton sponge-based amino acids into 2,3-dihydroperimidinium salts under air-oxygen was monitored with the help of the DMAN-alanine amino acid. The newly devised amino acids are unique as they combine fluorescence, strongly basic and redox-active properties.

[More] In this study, a sediment microbial fuel cell (SMFC) was explored to bioremediate polycyclic aromatic hydrocarbons (PAHs) in water originated from soil. The results showed consistent power generations of 6.02±0.34 and 3.63±0.37 mW/m(2) under an external resistance of 1500 Ω by the aerobic and anaerobic SMFC, respectively. Although the power generations were low, they had relatively low internal resistances (i.e., 436.6±69.4 and 522.1±1.8 Ω for the aerobic and anaerobic SMFC, respectively) in comparison with the literature. Nevertheless, the significant benefit of this system was its bioremediation capabilities, achieving 41.7%, 31.4% and 36.2% removal of naphthalene, acenaphthene and phenanthrene, respectively, in the aerobic environment and 76.9%, 52.5% and 36.8%, respectively, in the anaerobic environment. These results demonstrated the ability of SMFCs in stimulating microorganisms for bioremediation of complex and recalcitrant PAHs.

[More] Nanometer control over the porous shell thickness of sub-2-μm-shell particles is investigated. Three seeded growth mesoporous thin shell particles for HPLC were prepared, with 0.05μm (or 50nm) porous shell layers: particle sizes 1.5μm (solid core diameters 1.4μm), 1.7μm (solid core diameter 1.6μm), 1.9μm (solid core diameter 1.8μm) and compared with a fourth 1.7μm particle (solid core diameter 1.4μm) surrounded by 0.15μm (or 150nm) porous shell thickness. The thin shell particles were functionalised using a mono-functional octadecyldimethylchlorosilane ligand (C20H43SiCl) under optimised reflux conditions and packed in-house in narrow bore columns (2.1 I.D.×50mm) denoted as TS1.5-50-C18, TS1.7-50-C18, and TS1.9-50-C18 respectively. The synthesised thin shell particles and bonded materials were comprehensively characterised using scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), zeta potential, BET analysis, elemental analysis (CHN), thermogravimetric analysis (TGA) and diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy. Experimental data from inverse size exclusion chromatography (ISEC) was used to measure external, internal and total column porosities. Five probe analytes (uracil, naphthalene, acetophenone, benzene and toluene) were chosen for the chromatographic performance analysis of these columns. Column evaluation and measurements of height equivalent to a theoretical plate (HETP) data were performed on naphthalene using 55% acetonitile in water. The retention coefficients for the thin shell particles (TS1.9-50-C18, TS1.7-50-C18, TS1.5-50-C18) were in the range 1.26-1.35 and 5.6 for the core-shell particle (EiS1.7-150-C18). The minimum reduced plate heights range from 3.89 to 4.26 for the thin shell particles and 2.03 for the core-shell particle.

[More] A series of fifteen new N-alkoxyphenylanilides of 3-hydroxynaphthalene-2-carboxylic acid was prepared and characterized. Primary in vitro screening of the synthesized compounds was performed against Staphylococcus aureus, three methicillin-resistant S. aureus strains, Mycobacterium tuberculosis H37Ra and M. avium subsp. paratuberculosis. Some of the tested compounds showed antibacterial and antimycobacterial activity against the tested strains comparable with or higher than that of the standards ampicillin or rifampicin. 3-Hydroxy-N-(2-propoxyphenyl)naphthalene-2-carboxamide and N-[2-(but-2-yloxy)-phenyl]-3-hydroxynaphthalene-2-carboxamide had MIC = 12 µM against all methicillin-resistant S. aureus strains; thus their activity is 4-fold higher than that of ampicillin. The second mentioned compound as well as 3-hydroxy-N-[3-(prop-2-yloxy)phenyl]-naphthalene-2-carboxamide had MICs = 23 µM and 24 µM against M. tuberculosis respectively. N-[2-(But-2-yloxy)phenyl]-3-hydroxynaphthalene-2-carboxamide demonstrated higher activity against M. avium subsp. paratuberculosis than rifampicin. Screening of the cytotoxicity of the most effective antimycobacterial compounds was performed using THP-1 cells, and no significant lethal effect was observed for the most potent compounds. The compounds were additionally tested for their activity related to inhibition of photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. N-(3-Ethoxyphenyl)-3-hydroxynaphthalene-2-carboxamide (IC50 = 4.5 µM) was the most active PET inhibitor. The structure-activity relationships are discussed.
