Significance of Ionic strength
Ionic strength is a measure of the concentration of ions in a solution that can significantly influence various chemical processes. It impacts competitive adsorption of dye molecules, reaction rates, and the behavior of chemical systems. Ionic strength also affects the hydration and solubility of polymers in drug formulations, the stability of metal-ligand complexes, and the electric properties of skin formulations. Various studies indicate that while ionic strength is crucial, it can have negligible effects on reaction rates under certain conditions.

(1) The higher ionic strength of NaCl produces an increase in the current density at the same cell voltage, impacting the overall efficiency of the electrochemical process.[9] (2) Ionic strength refers to the concentration of ions in a solution, and the rise of ionic strength will lead to the inhibition of the adsorption capacity of certain contaminants on microplastics.[10] (3) Ionic strength, related to the concentration of ions in the solution, affects arsenic adsorption and desorption, influencing the interactions between arsenic and the surfaces of the media.[11] (4) A condition where, as it increases, the adsorption capacity decreases for all four adsorbents, and it was studied at three ionic states, 0, 0.01, and 0.1 M, obtained with KCl solution.[12] (5) Ionic strength may lead to a decrease in adsorption capacity because high concentrations of ions compete with antibiotics for adsorption sites on microplastics.[13]

(1) This is a measure of the concentration of ions in a solution, which can affect the efficiency of praseodymium migration in the microtubule ultrafiltration reactor.[14] (2) Ionic strength is a factor in environmental waters that can contribute to enhanced aggregation of CuO NPs, according to observations in the study.[15] (3) Ionic strength affects the adsorption of Cd(II) on manganese oxide, with the process decreasing with increasing ionic strength at pH < 5.0, but is independent at pH > 6.0.[16] (4) Ionic strength can affect zeta potential; if a solution containing NPs shifts to a lower ionic strength, then the zeta potential will increase because the EDL expands.[17] (5) The increased ionic strength caused a decrease in the equilibrium adsorption constant and the molecule binding strength of myoglobin.[18]
