Extraction of Na+, K+ and Li+ ions have been studied using dipropyleneglycoldibenzoate as carrier through organic liquid membranes viz. 1,2-dichloroethane, chloroform and carbontetrachloride. Picrates, dinitrophenolates and orthonitrophenolates have been used as anions. Higher extraction values were observed for Na+ than K+ and Li+ from picrate salts in 1,2-dichloroethane. K+ cation distributes itself to much extent among all cations. The results of extraction studies reveal that this selectivity can be used for fabrication of ion selective electrodes and sensors.
