Novel dye-attached macroporous films for cadmium, zinc and lead sorption: Alkali Blue 6B-attached macroporous poly(2-hydroxyethyl methacrylate)
(Elsevier Science Bv, 1998)
Alkali Blue GB-attached poly(2-hydroxyethyl methacrylate) (poly(HEMA)) microporous films were investigated as chelate forming sorbents for heavy metal removal. Poly(HEMA) microporous films were prepared by UV-initiated ...
The effects of the time-dependent and exposure time to air on Au epilayer n-Si Schottky diodes
(E D P Sciences, 1999)
A study on Au/n-Si Schottky barrier diodes (SBDs) parameters with and without thin native oxide layer fabricated on n-type Si grown by LPE (Liquid-Phase Epitaxy) technique has been made. The native oxide layer with different ...
Tautomeric properties, conformations and structure of N-(2-hydroxy-5-chlorophenyl) salicylaldimine
(Elsevier Science Bv, 1999)
The crystal structure of N-(2-hydroxy-5-chlorophenyl) salicylaldimine (C13H10NO2Cl) was determined by X-ray analysis. It crystallizes orthorhombic space group P2(1)2(1)2(1) with a = 12.967(2) Angstrom, b = 14.438(3) Angstrom, ...
Biosorption of inorganic mercury and alkylmercury species on to Phanerochaete chrysosporium mycelium
(Elsevier Sci Ltd, 1999)
The biosorption of inorganic mercury (HgCl2), methyl mercury (CH3HgCl) and ethyl mercury (C2H5HgCl) onto the dry biomass of Phanerochaete chryosponum was studied from aqueous media which concentrations in the range of 5-500 ...
Covalent immobilization of α-amylase onto pHEMA microspheres: preparation and application to fixed bed reactor
(Elsevier Sci Ltd, 1995)
Microspheres of poly(2-hydroxyethyl methacrylate) with and without cross-linker were prepared by suspension polymerization. As the amount of cross-linker increased, the equilibrium water content, enzyme loading, immobilization ...
3,3-Dichloro-1-(p-chlorophenyl)4-(p-methoxyphenyl)-2-azetidinone
(Wiley-Blackwell, 1999)
The crystal structure of the title compound, C16H12Cl3NO2, has a nearly planar beta-lactam ring with the N atom out of the best plane by 0.032(2) Angstrom. The C-C bond distances in the beta-lactam ring are 1.544(4) and ...
[N,N '-bis(5-bromosalicylidene)-1,3-diaminopropane]copper(II)
(Munksgaard Int Publ Ltd, 1999)
The title compound, [Cu(C17H14Br2N2O2)], has a crystallographic twofold axis. The coordination geometry about the Cu-II centre is a tetrahedrally distorted square plane formed by the four-coordinate N2O2 donor set of the ...
Determination of iron and nickel by flame atomic absorption spectrophotometry after preconcentration on Saccharomyces cerevisiae immobilized sepiolite
(Elsevier Science Bv, 1998)
Iron and nickel have been preconcentrated on Saccharomyces cerevisiae immobilized sepiolite and determined by flame atomic absorption spectrophotometry (FAAS). Preconcentration studies were conducted by the column method. ...
Adsorption of copper(II), cobalt(II), and iron(III) ions from aqueous solutions on poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 1998)
The adsorption behavior of poly(ethylene terephthalate) (PET) fibers towards copper(II), cobalt(II), and iron(III) ions in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment time, ...
Kinetic study of ligand exchange reaction of anions as ligands on DAE-sporopollenin
(Academic Press Inc Jnl-Comp Subscriptions, 1996)
The specific rate coefficients and ligand sorption isotherms of Br and I- as ligands on diaminoethyl-sporopollenin were determined as a function of pH and temperature between 20 and 60 degrees C. The ligand exchange rates ...
