Ion pairextraction is a technique used for the distribution ofionic compoundsto an organic phase with the aid ofcounterionsof opposite charge. Ion pairs are formed in the organic solvent, e.g., the extraction of a cation HA+with an anion X−making up an ion pair HAX, and the distributi...
(+) from the extremely hydrophilic chlorides.It has also been proved that the loaded Li in TBP can be effectively stripped by concentrated HCl solution with a Li/Fe separation factor>500.The understanding of the ion-pair transport mechanism is helpful for optimizing the recovery process or ...
a quasi-equilibrium transport model, a linear relationship with slope near 1 was obtained from a log-log plot of Caco-2 P (app) versus HNAP concentration, supporting the ion-pair mechanism behind the permeability enhancement. The potential of ion-pair formation to improve the ...
Among hydrophobic drugs, swelling rates in NH4SCN correlate poorly with octanol:water partition coefficients, suggesting that the rate of ion pair transport is determined by the formation constant for lipophilic ion pairs... KD Garlid,RA Nakashima - 《Journal of Biological Chemistry》 被引量: 166...
In this case, an optimal (Uinv, kinv) pair might be different for the cathode and the anode and one may need to compromise the speed of discharging at one of the electrodes. In practice, Uinv and kinv must be optimized for the entire supercapacitor. Experimental results With the same ...
Owing to polarizability, a single Cl− ion will more likely be extracted than a single Na+ ion or a Na–Cl ion pair. Figure 5e–h shows the charge density difference plots and its cross-sectional plots of a water molecule at the interfacial step. The water molecule adsorbed near Na+ ...
At the same time the charge transfer in the compound can be "effectively" described as the motion of Li-Li ion pairs with an intrapair ion distance equal to approximately the sum of the lithium ion radii. 关键词: HIGH-TEMPERATURE SUPERCONDUCTIVITY MICROWAVE CAVITIES SAMPLE SURFACE IMPEDANCE ...
The ion deflector () includes a pair of parallel flat electrodes ( and ) and deflects ions using a direct-current electric field. By causing the deflected ions to reach the ion receiving range of the rear-stage quadrupole ion guide (), it is possible to efficiency introduce ions while ...
Comparing the numerical values found here with the corresponding data determined for the system with NaCl solutions it is shown that cation-anion frictional force, which is usually assumed zero, cannot be neglected for the Na+-OH− pair of ions. These interactions influence diffusional and ...
