The use of an organic carrier consisting of di-(2-ethylhexyl) phosphoric acid (D2EHPA) and mono-(2-ethylhexyl) phosphoric acid (M2EHPA), diluted in kerosene, for separation of cadmium through a supported liquid membrane (SLM) was investigated. The extraction percentage of cadmium and permeability coefficients rose by increasing M2EHPA and feed phase concentration. By increasing the volume percentage of M2EHPA, the permeability coefficient of cadmium increased to a maximum value of 8 cm s 21 at 1?5 vol.-% declining at higher volume percentages. The permeability of cadmium ions through the SLM decreased with time. The permeation coefficient increased as the initial cadmium concentration increased.On a é tudié l'utilisation d'un support organique consistant d'acide phosphorique di-(2-é thylhexyle) (D2EHPA) et mono-(2-é thylhexyle) (M2EHPA), dilué dans du ké rosè ne, pour la sé paration du cadmium à travers une membrane liquide supporté e (SLM). Le pourcentage d'extraction du cadmium et les coefficients de permé abilité s'é levaient avec l'augmentation du M2EHPA et de la concentration de la phase d'alimentation. En augmentant le % de volume de M2EHPA, le coefficient de permé abilité du cadmium augmentait à une valeur maximale de 8 cm s 21 à un volume de 1?5% et dé clinait à des % plus é levé s du volume. La permé abilité des ions de cadmium à travers la SLM diminuait avec le temps. Le coefficient de permé ation augmentait avec l'augmentation de la concentration initiale de cadmium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
