Complexation of Oppositely Charged Polyelectrolytes: Effect of Ion Pair Formation [PDF]
Macromolecules, 2004 Complexation in symmetric solutions of oppositely charged polyelectrolytes is studied theoretically. We include polyion crosslinking due to formation of thermoreversible ionic pairs. The electrostatic free energy is calculated within the Random Phase Approximation taking into account the structure of thermoreversible polyion clusters. The degree of ion

Characterization of a mixed-reagent ion-pair complex
International Journal of Research in Engineering and Innovation, 2023 A method has been proposed for the determination of drug containing amino group phenylephrine hydrochloride (PHP) in pharmaceutical dosage forms. The method is based on the ion pair reaction of this drug with reagent (egg yellow) in alkaline medium to give intense orange colored product (λmax at 470 nm of PHP) with molar absorptivity values of 1.67 ...

Towards an analytical theory for charged hard spheres [PDF]
, 2007 Ion mixtures require an exclusion core to avoid collapse. The Debye Hueckel theory, where ions are point charges, is accurate only in the limit of infinite dilution. The MSA is the embedding of hard cores into DH, is valid for higher densities.
