Ion-pair reagents (IPRs), on the other hand, are added to the eluent to increase the retention of charged compounds. The underlying mechanism has been discussed for many years, and two main models are as follows: (i) ion-pair formation between the solute and lipophilic IPR bonded to the ...
Ion-pair formation in thallous solutions: IIIChemical shifts and spin-lattice relaxation times have been measured for the thallium resonance in solutions of thallous salts containing ferricyanide ions, and citrate ions. The results provide strong evidence that the ion-pairs which are formed in these ...
excited-state charge distribution, evincing large differences in both the ground- and excited-state dipole moment depending on whether X is a small associating anion (PF6−) that forms a contact-ion pair versus a large one that either dissociates or forms a solvent-separated pair (BArF4−...
5.2 Ion Pair Formation in Dimethylsulfoxide (DMSO) In this study we present the structure and equilibrium properties of CIPs and SIPs in mixtures of PILs and molecular solvents. A particular focus was put on the dependences of solvent polarity and solvent concentration. Some important questions are...
Base line separation of the chloroanions of the platinum group metals (Pt, Pd, Tr, Rh) in chloride media has been achieved using centrifugal partition chromatography (CPC) employing a heptane-water phase pair, by both complexation with trioctylphosphine oxide (TOPO) and ion pair formation with ...
Ion Pair Formation in Multiphoton Excitation of NO2 Using Linearly and Circularly Polarized Femtosecond Light Pulses: Kinetic Energy Distribution and Fragm... The NO2 ion pair photodissociation dynamics leading to NO+(X1Σ+,v) + O−(2P3/2 or 2P1/2), induced by a 1 kHz femtosecond laser...
The process could be named counterion-aided extraction rather than ion pair extraction, since the latter may indicate that ion pair formation in the aqueous phase is preceding the phase transfer. However, it should be emphasized that this is by no means an inevitable first step, although the ...
1) ion-pair formation 离子对缔合1. The mechanism that ion-pair formation was weaken by ion competition and extraction was carried out only based on H-b onding instead was proposed. 采用三元模拟体系 ,以三辛胺为萃取剂 ,在不同离子类型及离子强度下对丙酮酸的络合萃取过程进行了研究 ,证实无机阴...
2) ion pair formation 离子对生成3) generation probability 生成几率 1. The generation probability P N of ring polymer chain is theoretical analyzed and computer simulated. 建立了两端都被某一不可穿透的吸附壁物理吸附或化学结合的高分子环形链在格点上随行走的物理模型,对环形链的生成几率PN进行了...
