Web14 jul. 2015 · The results also indicated that although the pH and ionic strength of the solution played a significant role in the adsorption process, there was no significant influence on the adsorption capacity. Moreover, PIL-SAC could be reused at least five times with only minor losses in its adsorption capacity.
Ionic strength can be molar (mol/L solution) or molal (mol/kg solvent) and to avoid confusion the units should be stated explicitly. The concept of ionic strength was first introduced by Lewis and Randall in 1921 while describing the activity coefficients of strong electrolytes . Meer weergeven The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect … Meer weergeven The ionic strength plays a central role in the Debye–Hückel theory that describes the strong deviations from ideality typically encountered in ionic solutions. It is also important for … Meer weergeven • Ionic strength • Ionic strength introduction at the EPA web site Meer weergeven The molar ionic strength, I, of a solution is a function of the concentration of all ions present in that solution.
