Efficiency of membrane extraction of phenol-4-aminoantipyrine complex with n-alcohols
(Elsevier, Amsterdam, 2004)
In this study, the membrane extraction of phenol-4-aminoantipyrine complex with the series of aliphatic alcohols was investigated by monitoring the efficiency of the process. A commercial polysulphone hollow-fiber membrane ...
Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures
(Taylor & Francis Ltd, Abingdon, 2004)
The excess molar volume V data of the binary liquid systems were correlated by the Peng-Robinson-Stryjek-Vera equation of state coupled with two different types of mixing rules: composition dependent van der Waals mixing ...
Dynamic calibration of a sensor gas calorimeter for measurement of heat generation rates during kinetic of adsorption experiments
(Elsevier, Amsterdam, 2004)
A procedure for dynamic calibration of a sensor gas calorimeter, resulting with a calibration transfer function, instead with a calibration line, is presented. The main factors influencing the calibration transfer function ...
Synthesis and characterization of complexes between poly(itaconic acid) and poly(ethylene glycol)
(Springer, New York, 2004)
Interpolymer complexes of poly(itaconic acid) and poly(ethylene glycol) (PIA/PEG) were prepared by two different procedures: simple mixing of preformed PIA and PEG and by polymerization of itaconic acid on poly(ethylene ...
Thermodynamic modeling of vapor-liquid equilibria and excess properties of the binary systems containing diethers and n-alkanes by cubic equation of state
(Korean Institute Chemical Engineers, Seoul, 2004)
A comparison of the performances of two different approaches of cubic equations of state models, based on a classical van der Waals and mixing rules incorporating the G(E) equation, was carried out for correlation of ...
Protective properties of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloys
(Elsevier Science Sa, Lausanne, 2004)
A review is given on Zn-Ni alloys electrochemically deposited on steel under various deposition conditions. The influence of deposition current density and type of deposition solution on the chemical content, phase structure ...
Metal sorption on macroporous poly(GMA-co-EGDMA) modified with ethylene diamine
(Elsevier Science Bv, Amsterdam, 2004)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and modified by ...
Lipase immobilization in a hollow fibre membrane reactor: Kinetics characterization and application for palm oil hydrolysis
(Versita, Warsaw, 2004)
Feasibility of lipase immobilization in a hydrophilic hollow fibre membrane reactor for oil hydrolysis has been demonstrated. A simple immobilization technique was applied resulting in about 155 mg m(-2) of immobilized ...
Photoacoustic study of CO2-laser coincidences with absorption of some organic solvent vapours
(Elsevier, Amsterdam, 2004)
Detection of specific molecules in the atmosphere is motivated by the need for monitoring the emission of industrial pollutants. CO2-laser photoacoustic (PA) spectroscopy was used here to obtain coincidence spectra of the ...
Pertraction of phenol in hollow-fiber membrane contactors
(Elsevier, Amsterdam, 2004)
In this paper the multistage membrane pertraction (simultaneous extraction and reextraction) of phenol with linear monoalkyl cyclohexane (IMACH) as a carrier and sodium hydroxide solution as a strip, in laboratory scaled ...
