The phrase "alkaline concentration" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or environmental studies, to refer to the amount of alkaline substances present in a solution.
Example: "The alkaline concentration in the water sample was measured to determine its suitability for irrigation."
Alternatives: "alkaline level" or "alkaline content".
A higher alkaline concentration is favorable for oxidation at low potential with high current density.
Investigations on the formation process indicated that the citrate complexant, alkaline concentration and temperature played important roles for the formation of the special flowery nanostructures.
The kinetic analysis reveals the dependence of reaction resistances on the alkaline concentration, ion transfer, and reaction sites on the electrode surface, the latter is determined by the electrode materials.
The electrodialysis performances and power consumption for CO2 recovery and alkaline solution regeneration were examined using laboratory-scale electrodialysis equipment under various conditions; degree of CO2 absorption, CO2 recovery ratio, alkaline concentration, and type of cation exchange membrane.
The sandpack flood results show that the tertiary oil recovery can reach about 20% of the initial oil in place (IOIP) using 1.0% NaOH, and the tertiary oil recovery has been found to increase as the alkaline concentration increases.
The equilibrium relations between equilibrated organic sodium concentration and aqueous alkaline concentration for sodium extraction from sodium aluminate solutions under different concentrations of organic acid at various temperatures were systematically investigated.
The influence of alkaline concentrations on the structure, morphology, and optical properties of the samples has been systematically investigated.
In contrast to acidophilic bacteria, alkalophilic bacteria are able to grow in alkaline concentrations as great as pH 10 to 11. Alkalophiles have been isolated from soils, and most are species of the gram-positive genus Bacillus.
The effect of electrode material, alkaline concentrations, roughness, position and disk diameter of the electrode, gas pressure and of temperature upon the δ/gn relation is given.
Using these optimum alkaline concentrations, 22 displacement runs have been performed; 13 runs with the variable salinity of the alkaline solutions, six runs with the variable injection flow rate, and the remaining three runs were the base floods, performed without oil to see the interaction of alkaline solutions with the porous matrix.
The K++Na+, SO4 2− and Cl−, Ca2+ and Mg2+, and alkaline concentrations were determined by atomic absorption spectrometry, ion chromatography, EDTA titration, and acid-based titration, respectively.
