Solvent extraction and entrainment problem
(Association of Metallurgical Engineers of Serbia, 2020)
Applications of solvent extraction operations and processes play one of the most important roles in Hydrometallurgy. Therefore, in this brief review, some general concepts for selected representative applications are ...
Corrosion behavior and thermal stability of electrodeposited PANI/epoxy coating system on mild steel in sodium chloride solution
(Elsevier Science Sa, Lausanne, 2006)
The corrosion behavior, sorption characteristics and thermal stability of epoxy coatings electrodeposited on mild steel (MS) and mild steel with electrochemically deposited polyaniline (PANI) film were investigated in 3% ...
Thermal shock damage characterization of high temperature ceramics by non destructive test methods
(University of Chemistry and Technology, Prague, 2008)
In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with ...
Solubility and Pitzer's ionic parameters in the system H2O-NaCl-MgCl2
(University of Belgrade, Technical Faculty, Bor, 2001)
The object of this work was to determine Pitzer's ionic parameters, θ and Ψ, for the mixed salt solution H2O-NaCl-MgCl2 at following temperatures: 273.15, 298.15, 356.15 and 378.15 K in ionic strength interval from 7 to ...
Prediction of thermal shock behavior of alumina based refractories: Temperature difference, fracture resistance parameters and water quench
(Trans Tech Publications Ltd, Durnten-Zurich, 2001)
In this paper temperature difference and fracture resistance parameters were used for prediction of thermal shock behavior of the samples. Materials were alumina based commercial refractories with different content of Al2O3 ...
Using geothermal water for greenhouse heating
(Vinca Institute of Nuclear Sciences, 2006)
On construction with dimensions 15 x 5 x 2 m, conditions of temperature transmission and vegetables growth are examined. We have been cultivating pepper, cucumber, small cucumber, tomato, and lattice. Over ground heating ...
Osmotic coefficient of the ZnSO4(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2002)
The osmotic coefficient of ZnSO4(aq) has been measured at T = 298.15 K by the iso-piestic method, in the range of molalities from 1.3 to 3.0 mol . kg(-1), with KCl(aq) as the reference solution. Experimental data of osmotic ...
Accumulation of heavy metal(loid)s and polycyclic aromatic hydrocarbons in the sediment of the Prahovo Port (Danube) and associated risks
(Springer Science and Business Media Deutschland GmbH, 2023)
The current study investigated the concentrations, possible sources, toxicity, and ecological risk of eight heavy metal(loid)s (As, Cd, Cr, Cu, Hg, Ni, Pb, Zn) and sixteen priority polycyclic aromatic hydrocarbons (PAHs) ...
Nonlinear frequency response method for estimation of single solute adsorption isotherms. Part II Experimental study
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The aim of this paper is to investigate the possibility of applying a nonlinear frequency response (FR) method described by Ilic et al. [2007b. Nonlinear frequency response method for estimation of single solute adsorption ...
Physical and mathematical models of an inert macroelectrode modified with active hemispherical microelectrodes
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The physical model of an inert electrode partially activated with hemispherical microelectrodes was formed by the deposition of silver grains on a graphite substrate. It is shown that the process on the microelectrodes can ...
