in present study, molecular dynamics simulation of cadmium (ii), lead (ii) and copper (ii) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. the results showed that, most of the particles had the highest affinity of ion exchanging with lead (ii) and the lowest affinity with copper (ii). the calculated mean ion-exchange ratios showed t...

as igm and iga-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of igm and iga enriched immunoglobulins. fraction iii which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using sephadex deae a-50 and 0.1 m tris-d.35m naci buff...

the main goal of this study is to investigate the capability of zeolites a and p synthesized from iranian natural clinoptilolite for uranium uptak. the removal of uranium(vi) from aqueous solution via ion exchange by zeolites in a single component system with various contact times,  temperatures and initial concentrations of uranium(vi) was investigated. the experimental results were fitted to ...

Graphitic carbon nanocapsules, nanosheets and nanoplates were selectively obtained via a solid-state pyrolysis route from various ion-exchange resin-iron complexes.

We demonstrate the use of a novel pulse (18)O-(16)O isotopic exchange technique for the rapid determination of the oxygen surface exchange rate of oxide ion conductors while simultaneously providing insight into the mechanism of the oxygen exchange reaction, which contributes to the efficient development of devices incorporating these solids, such as solid oxide fuel cells and oxygen transport ...

-The process of solid-state film ion exchange (Ag +-Na +) in glass substrates for the fabrication of integrated, optical waveguides has been investigated as a solid-state electrochemical process. The ion exchange process is initiated by establishing a space-charge distribution in the more mobile charge carrier. The space charge establishes an intense electric field that drives oxygen to the sur...

A novel ester-rich copolymer/ionic liquid quasi-solid-state electrolyte (SPE-IL) was designed, and dual Li-ion migration channels (“association–disassociation” with the carbonyl groups rapid ion exchange ionic liquids) were built in it.
