Adsorption of heavy metal ions onto ethylene diamine-derived and Cibacron Blue F3GA-incorporated microporous poly(2-hydroxyethyl methacrylate) membranes
(Elsevier Science Bv, 2000)
Microporous poly( 2-hydroxyethylmethacrylate) (PHEMA) membranes carrying ethylene diamine (EDA) and Cibacron Blue F3GA were prepared for the removal of heavy metal ions (i.e. mercury, copper, lead and cadmium) from aqueous ...
Structures of four- and six-coordinate monomers of [N,N '-bis(5-chlorosalicylidene)-1,3-diaminopropane]nickel(II)
(Kluwer Academic/Plenum Publ, 2000)
[N,N' -Bis(5-chlorosalicylidene) -1,3 -diaminopropane] nickel(II) [Ni(C17H14N2O2Cl2)] 1 and [N,N' -Bis(5-chlorosalicylidene)-1,3 -diaminopropane] nickel(II) dihydrate [Ni(C17H14N2O2Cl2).2(H2O)] 2 were synthesized, and their ...
Removal of heavy metal ions from aquatic solutions by membrane chromatography
(Elsevier Science Bv, 2000)
Polyvinylalcohol membranes were prepared by a solvent casting technique. Metal-complexation ligand, i.e. monochlorotriazinyl-dye Cibacron Blue F3GA was then attached. These membranes with a high water content of 119%, and ...
In vitro cadmium removal from human serum by Cibacron Blue F3GA-thionein-complex conjugated affinity membranes
(John Wiley & Sons Ltd, 2000)
A new membrane affinity biosorbent carrying thionein has been developed for selective removal of cadmium ions from human serum. Microporous poly(2-hydroxyethyl methacrylate) (pHEMA) membranes were prepared by photopolymerization ...
Immobilization of glucoamylase onto spacer-arm attached magnetic poly(methylmethacrylate) microspheres: characterization and application to a continuous flow reactor
(Elsevier Science Bv, 2000)
Magnetic poly(methylmethacrylate) microspheres (MPMMA) were prepared by the solvent evaporation method and a 6-carbon spacer-arm (i.e. hexamethylene diamine, HMDA) was covalently attached by the reaction of carbonyl groups ...
Conformational study and structure of bis-N,N′-p-bromo-salicylideneamine-1,2-diaminobenzene
(Elsevier Science Bv, 2000)
Bis-N,N'-p-bromo-salicylideneamine-1,2-diaminobenzene (C20H14Br2N2 O-2) has been investigated by X-ray analysis and AM1 semi-empirical quantum mechanical method. Thc crystal is in the orthorhombic space group Pbca with a ...
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 ...
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 ...
