Phosphorus-nitrogen compounds. 14. Synthesis, stereogenism, and structural investigations of novel N/O spirocyclic phosphazene derivatives
(Amer Chemical Soc, 2007)
The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6, with N/O donor-type N-alkyl-o-hydroxybenzyl- and o-hydroxynaphthylamines result in novel mono-(3a, 4a and 4b), di- (5a and 5b), and tri- (3b, 6a, and 6b) spirocyclic ...
Removal of heavy mercury(II), cadmium(II) and zinc(II) metal ions by live and heat inactivated Lentinus edodes pellets
(Elsevier Science Sa, 2008)
The live and heat inactivated forms of Lentinus edodes pellets were used for the biosorption of Hg2+, Cd2+ and Zn2+ ions. The maximum adsorption of metal ions on the live and heat inactivated pellets of fungus was observed ...
Immobilization of glucose isomerase in surface-modified alginate gel beads
(Wiley, 2008)
In this study, glucose isomerase enzyme was entrapped into modified and nonmodified calcium alginate gel beads. Various characteristics of free and immobilized enzymes such as the optimum pH, temperature and dependence of ...
Preparation of nanofibrous polymer grafted magnetic poly(GMA-MMA)-g-MAA beads for immobilization of trypsin via adsorption
(Elsevier, 2008)
Poly (glycidylmethacrylate-methylmethacrylate), poly(GMA-MMA) beads were prepared via suspension polymerization in the presence of ferric ions. The epoxy groups of the poly(GMA-MMA) beads were converted into amino groups ...
Tetrakis(μ3-phenoxo-acetonitrilelithium), a tetrameric lithium aryloxide with a cubane core
(Int Union Crystallography, 2003)
The title compound, (CH3CNLiOC6H5)(4) or [Li-4 (C6H5O)(4) (C2H3N)(4)], is tetrameric with a distorted Li4O4 cube core. The molecule has crystallographic (4) over bar symmetry. Each Li atom has distorted tetrahedral ...
Poly[μ-aqua-aqua-μ-3-carboxypyrazine-2-carboxylato-sodium(I)]
(Int Union Crystallography, 2006)
The crystal structure of the title compound, [Na(C6H3N2O4)(H2O)(2)](n), consists of molecular ribbons containing octahedral NaO5N units. Two adjacent Na atoms are bridged by two water molecules to give a centrosymmetric ...
Adsorption of trypsin onto magnetic ion-exchange beads of poly(glycidylmethacrylate-co-ethyleneglycoldimethacrylate)
(John Wiley & Sons Inc, 2008)
Magnetic beads were prepared from glycidyl methacrylate (GMA), and ethyleneglycol dimethylmethacrylate (EGDMA) in the presence of Fe3O4 nanopowder via suspension polymerization. The magnetic beads were characterized by ...
Removal of Cd(II), Hg(II), and MID ions from aqueous solution using p(HEMA/Chitosan) membranes
(Wiley, 2007)
An interpenetration network (IPN) was synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan, p(HEMA/chitosan) via UV-initiated photo-polymerization. The selectivity to different heavy metal ions viz Cd(II), ...
Ca-alginate as a support for Pb(II) and Zn(II) biosorption with immobilized Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2003)
The basidio spores of Phanerochaete chryosporium were immobilized in alginate gel beads, and the immobilized spore containing alginate beads were incubated for the growth of fungus. The biosorption of Pb2+ and Zn2+ ions ...
Removal of chromium(VI) from aqueous solutions using poly(4-vinyl pyridine) beads
(Wiley, 2006)
Sorption of hexavalent chromium ions from aqueous solution by poly 4-vinyl pyridine [Poly(4-VP)] was studied. The batch method was applied for adsorption processes. The effects of initial ion concentration, time, pH and ...
