Abstract

Extraction and facilitated transport of alkali metal ions have been studied using ethyleneglycoldiacetate as a carrier through bulk liquid membranes using dichloromethane, 1, 2-dichloroethane and chloroform. Picrate, dinitrophenolate and orthonitrophenolate have been used as anions. Higher extraction and transport values were observed for sodium ions. Picrate anion is found to be the best in comparison to dinitrophenolate and orthonitrophenolate. Liquid membranes provide applications in organic synthesis, photochemical energy conversion and isomer and isotope separation techniques.
