Although not normally present in biological samples, nonionic surfactants can be present in calibrating, rinse, and quality control solutions used within modern automated electrolyte analyzers. This paper describes the effect of nonionic surfactants containing poly(ethylene oxide) units (Brij 35 and Triton X-100) within these structures and alkyl-N-methylglucamide-based (MEGA) surfactants on the potentiometic...
The reversibility of a host-guest reaction is known to follow a thermodynamic description of the equilibration process. This thermodynamic description distinguishes the enthalpic and the entropic term. Electrostatic interactions between hard ions and a ligand have been shown to be mainly entropy-stabilized which means that the predominant conformer of the ion-ligand complex is more stable than the...
