Osmotic and activity coefficients of {yKCl+(1-y)MgCl2}(aq) at T=298.15 k
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor-pressure measurements were made at the temperature 298.15 K for aqueous KCl + MgCl2 solutions using KCl(aq) as the reference standard. The measurements for these ternary solutions were made at KCl ionic ...
The influence of polypyrrole films on the corrosion behavior of iron in acid sulfate solutions
(Elsevier Science Sa, Lausanne, 1998)
The corrosion behavior of mild steel covered by electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from an aqueous solution of ...
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 ...
Correlation of osmotic coefficient data for ZnSO4(aq) at 25 degrees C by various thermodynamic models
(Kluwer Academic/Plenum Publ, New York, 2003)
The available literature data on the osmotic coefficient of ZnSO4(aq) at 25degreesC in the molality range from 0.1 to 4.3 mol-kg(-1) and new experimental data from 1.2 to 2.9 mol-kg(-1), at the same temperature, are ...
A new approach to the velocity field investigation in case of the entry flow in curved pipes with circular cross section
(Springer Wien, Wien, 2000)
In this paper an analysis of a laminar flow in a bend preceded by the straight section is presented. The flow is supposed to be unperturbed far upstream, while far downstream it becomes fully developed. In the vicinity of ...
Hydrogels based on 2-hydroxyethyl methacrylate obtained by gamma irradiation
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Hydrogels based on 2-hydroxyethyl methacrylate and different types of poly(alkylene glycol) acrylates and methacrylates, with a small percent of itaconic acid, have been prepared by solution copolymerization using gamma ...
Synthesis of substituted 3-cyano-2-pyridones: Part III - Enzyme kinetics
(Natl Inst Science Communication, New Delhi, 1998)
Lipases from Candida cylindracea and hog pancreas have been used to study the reaction kinetics of enzyme catalysed synthesis of substituted 3-cyano-2-pyridones by cyclization of 1,3-diketones with cyanoacetamide. Influence ...
Sulphatization of manganese slime from zinc electrolysis with ferrosulphate
(Wiley, Hoboken, 1998)
The kinetics and mechanism of the sulphatization of manganese slime from the zinc electrolysis with Fe(ll) sulphate was studied. The priority of chemical reactions was determined on the basis of the results of thermodynamic ...
Electrodeposition of silver from nitrate solution: Part II. Mechanism of the effect of phosphate ions
(Springer, Dordrecht, 1998)
The mechanism of compact Ag-film formation by electrolysis from nitrate solution with addition of small amounts of phosphate ions is elucidated. It is shown that the phosphate ions exert their effect by lowering the exchange ...
Theoretical assessment of calcium arsenates stability: Application in the treatment of arsenic contaminated waste
(8th Conference of the Yugoslav Materials Research Society, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca5(AsO4)3 OH have been proposed. These immobilization techniques ...
