Depositions of calcium oxalate on process equipment can be a great problem when the degree of system closure of a bleach plant in a kraft pulp mill is increased. As part of an equilibrium model for bleach plant filtrates, an equilibrium model has been developed involving aqueous solutions and...
The presence of calcium and magnesium affects the purity of the final product MnCl2 in hydrometallurgical treatment processes. The solvent extraction method can be used to separate Ca2+ and Mg2+ from Mn2+ solutions containing impurity ions such as Ca2+ and Mg2+. This article aims to investig...
equilibrium potential of the intermetallic compounds formed by lanthanide elements and zinc and their atomic radius.This equation is not only applicable to lanthanide elements but also hold for other elements such as alkali metal lithium,alkaline earth metal magnesium,calcium and transition metal niobium...
these should be considered at least as concurrent selection pathways. Historically, the Formose reaction has been considered the major pathway, by which ribose could be formed. However, detailed
Gibbs-Donnan potential is passive; that is, energy is not necessary for its establishment. In contrast, the resting potential is actively generated (indirectly or directly) by the action of the Na + -K + pump. The resting potential of most cells in the body, including nerve and muscle ...
The canonical equilibrium properties of classical Coulomb systems are investigated in 2 + dimensions for any value of the plasma parameter 螞 = e 2 k BT... C Deutsch,Y Furutani,MM Gombert - 《Physics Reports》 被引量: 64发表: 1981年 Strontium substitution in bioactive calcium phosphates: a...
A small membrane potential will bias either ion to dissociate on one side of the membrane. The different koff rates for Na þ and K þ primarily alter how quickly an ion dissociates from the channel, not which side it will dissociate. So if the two ions have similar association rates ...
If Cp*2OsH+ is used as an anchoring point, ΔHMH+ (DCE) can be converted to pKa (acetonitrile) data which in conjunction with the pertinent E°(M/M+) electrode potential gives access to M–H BDEs for the cationic hydrides using Equation (7), Scheme 3. Wang and Angelici proposed ...
calcium ions. Solubility of ferrous iron and the solid-phase minerals that would be stable in a solution containing activities of 10 ppm of sulfate and 100 ppm of bicarbonate or related species is expressed by means of a stability-field diagram with pH as abscissa and redox potential as ...
Influence of soil pH on the nitrate-reducing microbial populations and their potential to reduce nitrate to NO and N2O Slurries of an acid forest soil (pH 4.0) and two slightly alkaline agricultural soils (pH 7.6鈥 7.8) were adjusted to pH values between 3.8 and 7.8 and test... W N?Gele...
