Functionalization of low molecular weight atactic polypropylene - Part II. Thermal and molecular weight studies
(Springer, 2000)
Number average molecular weight (M-n), intrinsic viscosity ([eta]) and glass transition temperature (T-g) of low molecular weight atactic polypropylene (APP) grafted with 4-allyl-1,2-dimethoxybenzene (DMAB), 4-allyl-2-me ...
Intramolecular hydrogen bonding and tautomerism in Schiff bases. Part II. Structures of 1-[N-(2-pyridyl)aminomethylidene}-2(1H)-naphtalenone (1) and bis[2-hydroxy-κO–N-(2-pyridyl)-1-naphthaldiminato-κN]zinc(II) (2)
(Elsevier Science Bv, 2000)
The Schiff base ligand (1) and its Zn(II) complex (2) have been synthesized and their crystal structures have been determined. Compound (1) crystallizes in the monoclinic space group C2/c with a = 26.993(2), b = 5.891(1), ...
Separation and speciation of Cr(III) and Cr(VI) with Saccharomyces cerevisiae immobilized on sepiolite and determination of both species in water by FAAS
(Elsevier Science Bv, 2000)
A rapid, sensitive and accurate method for the separation, preconcentration and determination of Cr(III) and Cr(VI) in water samples is described. Chromium species can be separated by biosorption on Saccharomyces cerevisiae ...
Adsorption behavior of copper(II) ion from aqueous solution on methacrylic acid-crafted poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 2000)
The adsorption behavior of methacrylic acid-grafted poly(ethylene terephthalate) fibers was studied toward the copper(II) ion in aqueous solutions by a batch equilibriation technique. The influence of treatment time, ...
Determination of zinc, cadium, cobalt and nickel by flame atomic absorption spectrometry after preconcentration by poly(ethylene terephthalate) fibers grafted with methacrylic acid
(Pergamon-Elsevier Science Ltd, 2000)
A method for the determination of Zn, Cd, Co and Ni by flame atomic absorption spectrophotometry after preconcentrating on poly(ethylene terephthalate) fibers grafted with methacrylic acid has been developed. The batch ...
Determination of Cu, Zn, Fe, Ni and Cd by flame atomic absorption spectrophotometry after preconcentration by Escherichia coli immobilized on sepiolite
(Elsevier Science Bv, 2000)
A method for the determination of Cu, Zn, Fe, Ni and Cd by flame atomic absorption spectrophotometry (FAAS) after preconcentrating on a column containing Escherichia coli immobilized on sepiolite has been developed. Optimum ...
Novel hydrophobic ligand-containing hydrogel membrane matrix: preparation and application to gamma-globulins adsorption
(Elsevier Science Bv, 2001)
In this study, phenylalanine as a hydrophobic ligand was covalently attached to the co-monomer methacrylochloride. Then, poly(2-hydroxyethylmethacrylate-co-methacrylamidophenyalanine) [poly(HEMA-MApA)] membranes were ...
Surface energy components of a dye-ligand immobilized pHEMA membranes: Effects of their molecular attracting forces for non-covalent interactions with IgG and HSA in aqueous media
(Elsevier, 2005)
In the present paper, we report the study of the adsorption behaviour of human immunoglobulin G (IgG), human serum albumin (HSA) and polyethylenimine (PEI) onto surfaces of Procion Green HE-4BD (PG) immobilized ...
Electrochemical polymerization of 4-allyl-1,2-dimethoxybenzene
(Elsevier Science Bv, 2004)
Redox behaviour of 4-allyl-1,2-dimethoxybenzene (DMAB) was studied by using cyclic voltammetry and electro-chemical polymerization was conducted at the measured peak potential. Constant potential electrolysis of the monomer ...
Controlled release of insecticide carbaryl from crosslinked carboxymethylcellulose beads
(Parlar Scientific Publications (P S P), 2004)
Copper-carboxymethylcellulose (CuCMC) beads containing carbaryl were prepared by the ionotropic crosslinking of sodium carboxymethylcellulose (NaCMC) with copper ions. The beads were characterized by carbaryl encapsulation ...
