XRF Analysis of Heavy Metals for Surface Soil of Qarun Lake and Wadi El Rayan in Faiyum, Egypt
(Scientific Research, 2013-07)The environmental pollution with some heavy metals for twenty four surface soil samples collected from Qarun Lake and Wadi El Rayan region in Faiyum, Egypt utilizing X-ray fluorescence (XRF) spectroscopy was measured. The ... -
Comparative Study on Heavy Metals Biosorption by Different Types of Bacteria
(Scientific Research, 2013-07)Biosorption of Cd(II), Ag(I) and Au(III) by cyanobacteria Spirulina platensis, of Au(II)—by Streptomyces spp. 19H, and of Cr(VI) and Cr(III)—by Arthrobacter species was studied by using the dialysis and atomic absorption ... -
Assessment of Heavy Metals Immobilization in Artificially Contaminated Soils Using Some Local Amendments
(Scientific Research, 2013-07)Three alluvial soil samples with different textures were artificially polluted with chloride solutions of Cd, Pb, Co and chromate solution for Cr. The aqua-regia extracted concentration ranges in the artificially polluted ... -
Heavy Metal Contaminated Food Crops Irrigated with Wastewater in Peri Urban Areas, Zambia
(Scientific Research, 2013-07)Studies on peri urban farming in Zambia have not adequately tackled the issues pertaining to heavy metal contaminated wastewater irrigation farming. The study investigated heavy metal contamination of water, soils and ... -
A Novel Technique for Determination of Flow Characteristics of Blast Furnace Slag
(Scientific Research, 2012-06)A study of flow characteristics of blast furnace slag helps determine its softening and flow (liquid-mobility) temperatures. The slag with a narrow difference between the two temperatures is termed a “Short Slag”. Its ... -
Updated Definition of the Three Solvent Descriptors Related to the Van der Waals Forces in Solutions
(Scientific Research, 2018-02)Innovative viewpoint on the older topic of the van der Waals forces, is of interesting and significant issue to be concerned in both the fields related to the fundamental investigation and thus valuable in guiding the ... -
Simplified Step-by-Step Nonlinear Static Program Investigating Equilibrium Conditions of Electrons in Atom and Ionization Energies: Case Study on Argon
(Scientific Research, 2018-05)For investigation of equilibrium conditions of electrons in an atom, and Ionization Energies of Elements, a simplified deterministic static model is proposed. The electrons are initially uniformly and sparsely arranged ... -
A Specific Periodic Table for Chemistry of Organic, Semi-Organic and Inorganic Elements: Compatibility with the Even-Odd Rule,the Number of Electrons and the Isoelectronicity Rule
(Scientific Research, 2018-05)Following the introduction of the new even-odd and isoelectronic rules and definitions affecting the understanding of electronic structure and bonds, the author has thought necessary to summarize understandings in the ... -
The Relation between the Heat of Melting Point, Boiling Point, and the Activation Energy of Self-Diffusion in Accordance with the Concept of Randomized Particles
(Scientific Research, 2014-11)On the example of typical metals, it’s found that the activation energy of self-diffusion is above of the melting heat and below of vaporization heat. This corresponds to the existence of liquid-mobile particle classification ... -
Molecular Simulation of Ion Transport at the Water/Vapor Interface
(Scientific Research, 2012-08)Molecular dynamics was used to quantify the role of the size, charge and polarisability of F– , Cl– , Br– , I– and Na+ ions in their distribution in the water/vapour interface system. Our results show that the ... -
