Dendrimers are exotic multi-functional ligands and expected to give rise better extraction/transport results as compared the mono-functional ligands. Diglycolamide (DGA) based dendrimers scarcely reported literature on their transport studies very limited. Transport of Am(III) Eu(III) across a PTFE (polytetrafluoroethylene) flat sheet supported liquid membrane containing generation 1 dendrimer ...

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Carbon membrane can be produced using a wide variety of polymer precursor materials via heat treatment process. A general concept route of precursor selection-preparation-modification-performance analysis platform for the carbon membrane has been proposed to promote the development of carbon membrane material for a wide range of application. The current review considers the recent progress of c...

There is a growing need to develop technologies that can separate and selectively remove hazardous chemical species from waste effluents. Selective removal of cadmium ions through a supported liquid membrane (SLM) containing triethanolamine (TEA) as a mobile carrier has been studied. The effects of Cd(II) concentration, HCl in feed and carrier concentration in membrane has been studied. Cd(II) ...

A comprehensive study pertaining to the emulsion liquid membrane (ELM) extraction process to enrich dilute aqueous solutions of silver salt is presented. The study has highlighted the importance and influence of membrane composition for maximizing the extraction of Ag+ ions. The liquid membrane was made up of Cyanex-302 as an extractant and the industrial solvent mainly consists of p...
