Performance of different metal-dye chelated affinity adsorbents of poly(2-hydroxyethyl methacrylate) in lysozyme separation
(Marcel Dekker Inc, 2000)
The triazine dye Cibacron Blue F3GA was covalently immobilized as an affinity ligand onto microporous poly(2-hydroxyethyl methacrylate) (pHEMA) membranes. Three different metal ions [i.e.. Fe(III), Zn(II), or Cu(II)] were ...
Biodegradation of aldicarb in a packed-bed reactor by immobilized Methylosinus
(Elsevier Science Inc, 1999)
Carboxymethylcellulose microspheres cross-linked via aluminum ions were used as a support material for immobilization of Methylosinus isolated from soil contaminated with aldicarb. The degradation capacity of immobilized ...
Intramolecular hydrogen bonding and tautomerism in 1-[N-(4-bromophenyl)]aminomethylidene-2(1H) naphthalenone
(Kluwer Academic/Plenum Publ, 2000)
1-[N-(4-bromophenyl)]aminomethylidene-2(1H)naphthalenone (C17H12NOBr) (1) was synthesized and its crystal structure was determined. Compound (1) is monoclinic, space group P2(1)/n with a = 4.808(1) Angstrom, b = 20.617(1) ...
Effect of annealing period on the resistive transitions and AC losses in a Bi1.6Pb0.4Sr2Ca3Cu4O12 superconductor fabricated by a wet technique
(Elsevier Science Sa, 2000)
We estimated the irreversibility lines from the resistive-superconducting transition in DC magnetic fields up to 1 T for the Bi1.6Pb0.4Sr2Ca3Cu4O12 superconducting samples prepared by liquid ammonium nitrate with the same ...
The Detection of Mutagenic Activity of Some Chemicals (Azamethyphos, Dichlor zamethyphos, Dichlorvos, Methyl par os, Methyl parathion, Aflat athion, AflatoxinB1) b xinB1) by SMART Drosophila melanogaster
(Scientific Technical Research Council Turkey, 2000)
In this study mutagenic effects of some chemicals used in Veterinary Medicine and agricultural fields was investigated by Somatic Mutation and Recombination Test (SMART). SMART test was to observe the chemical effects on ...
Structure and conformation of 2,3,4-triphenyl-1-oxa-4-azabutadiene
(Elsevier Science Bv, 2000)
2,3,4-triphenyl-1-oxa-4-azabutadine (C20H15NO) has been studied by X-ray analysis and AMI molecular orbital methods. It crystallises in the triclinic space group P-l with a = 9.414(3), b = 10.479(3), c = 8.385(2) Angstrom, ...
Dithiocarbamate-incorporated monosize polystyrene microspheres for selective removal of mercury ions
(Elsevier Science Bv, 2000)
Dithiocarbamate-incorporated monosize polystyrene based microspheres (2 mu m in diameter) were used for selective removal of Hg(II) from aqueous solutions containing different amounts of Hg(II) (10-100 ppm). Adsorption ...
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
(Taylor & Francis Ltd, 1999)
Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate ...
Removal of cadmium(II) ions from human plasma by thionein modified pHEMA based membranes
(Elsevier Science Bv, 2000)
Microporous poly(2-hydroxyethylmethacrylate) [pHEMA] membranes carrying Cibacron Blue F3GA and/or thionein were prepared and used for cadmium(II) removal from human plasma. pHEMA membranes were produced by a photopolymerization ...
β-galactosidase immobilization into poly(hydroxyethyl methacrylate) membrane and performance in a continuous system
(Wiley-Blackwell, 1999)
The activity of beta-galactosidase immobilized into a poly(2-hydroxyethyl methacrylate) (pHEMA) membrane increased from 1.5 to 10.8 U/g pHEMA upon increase in enzyme loading. The K-m values for the free and the entrapped ...
