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 ...
Affinity microspheres and their application to lysozyme adsorption: Cibacron Blue F3GA and Cu(II) with poly(HEMA-EGDMA)
(Wiley, 1999)
Lysozyme adsorption onto Cibacron Blue F3GA attached and Cu(II) incorporated poly(2-hydroxyethyl methacrylate-ethylene glycol dimethacrylate) [poly(HEMA-EGDMA)] microspheres was investigated. The microspheres were prepared ...
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. ...
Biosorption of inorganic mercury and alkylmercury species on to Phanerochaete chrysosporium mycelium
(Elsevier Sci Ltd, 1999)
The biosorption of inorganic mercury (HgCl2), methyl mercury (CH3HgCl) and ethyl mercury (C2H5HgCl) onto the dry biomass of Phanerochaete chryosponum was studied from aqueous media which concentrations in the range of 5-500 ...
Immobilization of catalase in poly(isopropylacrylamide-co-hydroxyethylmethacrylate) thermally reversible hydrogels
(John Wiley & Sons Ltd, 1999)
Catalase was entrapped in thermally reversible poly (isopropylacrylamide-co-hydroxyethyl-methacrylate) (pNIPAM/HEMA) copolymer hydrogels. The thermoresponsive hydrogels, in cylindIl-rical geometry, were prepared in an ...
Wastewater treatment at the petroleum refinery, Kirikkale, Turkey using some coagulants and Turkish clays as coagulant aids
(Pergamon-Elsevier Science Ltd, 1998)
In this study, waste water of Kirikkale Refinery (Turkey) was treated with coagulants (alum, ferric chloride, ferrous sulfate and lime) and coagulant aids (polyelectrolytes: anionic, cationic, nonionic) and some Turkish ...
Determination of Cu, Zn and Cd in water by FAAS after preconcentration by baker's yeast (Saccharomyces cerevisiae) immobilized on sepiolite
(Springer Verlag, 1999)
By using the adsorbent Saccharomyces cerevisine immobilized on sepiolite an adsorption-elution method was developed for the preconcentration of Cu, Zn, and Cd followed by flame atomic absorption spectrometry (FAAS). ...
Immobilization of glucose oxidase and urease in hydrogel matrices
(Scientific Technical Research Council Turkey, 1997)
Immobilization of glucose oxidase and urease in hydrogels of 2-hydroxyethyl methacrylae, and N-vinyl pyrrolidone (NVP) was achieved by irradiation (using UV kand gamma-rays). The effect of radiation on entrapment efficiencies, ...
Controlled release of Aldicarb from carboxymethylcellulose microcapsules
(Scientific Technical Research Council Turkey, 1997)
Sodium carboxymethyl cellulose was converted into microspheres by crosslinking with aluminum chloride. Various microsheres with different amounts of crosslinker, biopolymer of various concentrations and molecular weights, ...
Failure analysis of two-dimensional carbon-epoxy composite plate pinned joint
(Taylor & Francis Inc, 1999)
The aim of this study is to investigate failure strength and failure mode of a mechanically fastened carbon-epoxy composite plate of arbitrary orientation. The failure load and the failure mode are analyzed numerically and ...
