Adsorption of copper(II), cobalt(II), and iron(III) ions from aqueous solutions on poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 1998)
The adsorption behavior of poly(ethylene terephthalate) (PET) fibers towards copper(II), cobalt(II), and iron(III) ions in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment time, ...
3,3-Dichloro-1-(p-chlorophenyl)4-(p-methoxyphenyl)-2-azetidinone
(Wiley-Blackwell, 1999)
The crystal structure of the title compound, C16H12Cl3NO2, has a nearly planar beta-lactam ring with the N atom out of the best plane by 0.032(2) Angstrom. The C-C bond distances in the beta-lactam ring are 1.544(4) and ...
A noise reduction algorithm in ECG signals using wavelet transform
(Ieee, 1998)
A noise reduction algorithm based on multiresolution orthogonal wavelet transform in ECG signals is discussed. The results are presented for different analysis and synthesis filter coefficients proposed by Vetterli-Herley ...

Preparation and characterization of magnetic polymethylmethacrylate microbeads carrying ethylene diamine for removal of Cu(II), Cd(II), Pb(II), and Hg(II) from aqueous solutions
(John Wiley & Sons Inc, 2000)
Magnetic polymethylmethacrylate (mPMMA) microbeads carrying ethylene diamine (EDA) were prepared for the removal of heavy metal ions (i.e., copper, lead, cadmium, and mercury) from aqueous solutions containing different ...
Procion blue MX-3G-attached microporous poly(2-hydroxyethyl methacrylate) membranes for copper, arsenic, cadmium, and mercury adsorption
(Marcel Dekker Inc, 1999)
pHEMA membranes carrying 25.6 mmol Procion Blue MX-3G/m(2) were used for removal of heavy metal ions (i.e., copper, arsenic, cadmium, and mercury) from aqueous media containing different amounts of these ions (0.1-4.5 ...
Monosize and non-porous p(HEMA-co-MMA) microparticles designed as dye- and metal-chelate affinity sorbents
(Elsevier Science Bv, 2000)
Congo red was immobilised onto monosize and non-porous poly(2-hydroxyethylmethacrylate-co-methylmethacrylate) [p(HEMA-co-MMA)] copolymer microparticles (4.0 mu m in diameter). Then Fe(III) ions were complexed by chelation ...
Affinity interaction of hydroxypyruvate reductase from Methylophilus spp. with Cibacron blue F3GA-derived poly(HEMA EGDMA) microspheres: partial purification and characterization
(Elsevier Sci Ltd, 1999)
A methylotrophic hydroxypyruvate reductase was partially purified and characterized from Methylophilus spp. using the biomimetic dye, Cibacron Blue F3FA attached to poly(HEMA-EGDMA) microspheres. The absorption capacities ...
Effect of cyclodextrin-encapsulated β-carotene on progesterone production by bovine luteal cells
(Elsevier Science Bv, 2000)
Experiments were conducted to examine the effect of cyclodextrin-encapsulated beta -carotene on basal or cholesterol (cyclodextrin-encapsulated), LH and dibutyryl cyclic AMP (dbcAMP)stimulated progesterone production by ...
Determination of iron and nickel by flame atomic absorption spectrophotometry after preconcentration on Saccharomyces cerevisiae immobilized sepiolite
(Elsevier Science Bv, 1998)
Iron and nickel have been preconcentrated on Saccharomyces cerevisiae immobilized sepiolite and determined by flame atomic absorption spectrophotometry (FAAS). Preconcentration studies were conducted by the column method. ...
