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.
Adsorption rate was investigated using the values of dye adsorbed at different initial dye concentrations, stirring speeds, adsorbent dosages, ionic strengths, temperatures and pHs as a function of reaction time.
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.
