Spectrophotometric Determination of Hg2+ after Solid Phase Extraction on Microcrystalline Naphthalene

Mercury is quantitatively retained with 1, 5-diphenylcarbazone (DPC) on microcrystallinenaphthalene in the pH range 6.5-8.5 from a large volume of aqueous solutions of various samples.After filtration, the solid mass consisting of the mercury complex and naphthalene was dissolvedin 5.0 mL of dimethylformamide (DMF) and mercury was determined by spectrophotometricmethod at 542 nm against the rea...

Quantitative SERS sensors for environmental analysis of naphthalene.

In the investigation of chemical pollutants, such as PAHs (Polycyclic Aromatic Hydrocarbons) at low concentration in aqueous medium, Surface-Enhanced Raman Scattering (SERS) stands for an alternative to the inherent low cross-section of normal Raman scattering. Indeed, SERS is a very sensitive spectroscopic technique due to the excitation of the surface plasmon modes of the nanostructured metal...

Characterization of naphthalene-degrading bacteria isolated from the Persian Gulf and the Caspian Sea as potential agents for naphthalene removal from polluted environments

Over fifty bacterial strains were isolated from seawater samples in the presence of naphthalene as a sole source of carbon and energy. Among them, three isolates with higher growth rate and naphthalene degradation ability were selected for further studies. Biochemical and molecular analysis revealed that two Persian Gulf isolates, strain PG-10 and strain PG-48 belonged to the group of hydrocarb...

Gold-catalyzed naphthalene functionalization

The complexes IPrMCl (IPr = 1,3-bis(diisopropylphenyl)imidazol-2-ylidene, M = Cu, 1a; M = Au, 1b), in the presence of one equiv of NaBAr'(4) (Ar' = 3,5-bis(trifluoromethyl)phenyl), catalyze the transfer of carbene groups: C(R)CO(2)Et (R = H, Me) from N(2)C(R)CO(2)Et to afford products that depend on the nature of the metal center. The copper-based catalyst yields exclusively a cycloheptatriene ...
