ionic strength

[ī′än·ik ′streŋkth]
(physical chemistry)
A measure of the average electrostatic interactions among ions in an electrolyte; it is equal to one-half the sum of the terms obtained by multiplying the molality of each ion by its valence squared.

This is achieved by varying pH, introducing ions at different ionic strengths as well as by changing viscosities.
The subsequent GWPI had greater heat stability at a wide range of pH and ionic strengths.
Different ionic strengths of the solution in the EDLs and of the bulk solution may cause diverse ionic mobilities in the two solution phases (Bockris and Reddy 1972).
Topics include: correlations of the PZC and isoelectric points (IEP) with other physical quantities and properties, surface charging in mixed and nonaqueous solvents, surface charging at high ionic strengths, and ion-specificity in 1-1 electrolytes.
and OH adsorption-pH curves at different ionic strengths was reported as the soil PZSE.
Several such runs were performed consecutively for different samples of the membrane at ionic strengths of 0.
In conclusion, we demonstrate an improved photonic crystal glucose sensor consisting of a polyacrylamide-PEG polymer network with an embedded CCA that reports on glucose concentrations at physiologic ionic strengths and at pH 7.
2] (second dissociation constant of MOBS), (b) the evaluation of pH values for six dilute buffer solutions in which NaCl has been added in amounts sufficient to raise the ionic strengths to 0.
The immobilization conditions are very mild; room temperature, compatibility with standard buffers and ionic strengths, and highly specific covalent bond formation.
Variable surface charge soil changes the magnitude and sign of its charge with the pH, but a the ionic strength may also modify the magnitude of its charge, which can be easily observed through potentiometric titration curves carried out at different ionic strengths (Fig.
The solvency is likely affected at high ionic strengths (Marra et al.
