gNMR simulated H-1 and proton-coupled C-13 NMR spectra of substituted 3-nitropyridines. GIAO/DFT calculated values of proton and carbon chemical shifts and coupling constants
(Elsevier Science BV, 2006)
The magnitude of one bond and long-range coupling constants in 3-nitropyridine 1 and its derivatives 2-16 were determined from the proton-coupled C-13 NMR spectra in CDCl3. The GIAO/DFT (Density Functional Theory/Gauge ...
Equilibrium and kinetics of biosorption of lead(II) from aqueous solutions by Cephalosporium aphidicola
(Elsevier Science BV, 2006)
Biosorption of lead(II) onto Cephalosporium aphidicola was examined and the effects of pH, contact time, biosorbent and lead(II) concentrations and temperature on biosorption were investigated. The nature of the possible ...
Binding behavior of Fe3+ ions on ion-imprinted polymeric beads for analytical applications
(John Wiley & Sons Inc, 2006)
We used a molecular imprinting approach to achieve specific metal binding utilizing N-methacryloyl-(L)cysteine methyl ester (MAC) as a metal-complexing ligand. MAC was synthesized using methacryloyl chloride and cysteine ...
Measurement and correlation of solubility of Acid Red 57 in supercritical carbon dioxide by ion-pairing with hexadecyltrimethylammonium bromide
(Elsevier Science BV, 2006)
Solubility of C.I. Acid Red 57 (AR57) in supercritical carbon dioxide was measured by ion-pairing with hexadecyltrimethylammonium (HDTMA) bromide. The solubility measurements of AR57 and AR57-HDTMA in supercritical carbon ...
Affinity separation of immunoglobulin G subclasses on dye attached poly (hydroxypropyl methacrylate) beads
(Elsevier Science BV, 2006)
Poly(hydroxypropyl methacrylate) [poly(HPMA)] gel beads with an average size of 150-200 mu m were prepared by suspension polymerization of hydroxypropyl methacrylate (HPMA). The poly(HPMA) gel beads were characterized by ...
Synthesis and characterization of pseudo-affinity ligand for penicillin acylase purification
(Elsevier Science BV, 2006)
The aim of this work was to test a chromatographic affinity support containing methacryloyl antipyrine (MAAP) for penicillin acylase (PA) purification by using pure penicillin acylase and crude extract. First, MAAP as a ...
Ion-selective imprinted beads for aluminum removal from aqueous solutions
(American Chemical Society, 2006)
The aim of this study is to prepare ion-imprinted polymers that can be used for the selective removal of aluminum ions [Al3+] from aqueous solutions. N-Methacryloyl-L-glutamic acid (MAGA) was chosen as the complexing ...
Preconcentration of copper using double-imprinted polymer via solid phase extraction
(Elsevier Science BV, 2006)
The aim of this study is to prepare double-imprinted polymers which can be used for the selective removal of Cu(II) ions from synthetic waters. Chitosan-succinate (CS) was choosen as the metal complexing polymer. In the ...
