The invention relates to a lithium ion-selective membrane, including a polymer carrier, a plasticizer, a conductive compound and a lithium ion specific ionophoric compound. The invention consists in that said ionophoric compound is dibenzyl-14-crown-4 and derivatives thereof, and represents between 0.5 and 3 % by weight of the total composition of the membrane, the polymer carrier representing 25 to 30% by weight of the total composition of the membrane, the plasticizer from 65 to 72% by weight of the total composition of the membrane and the conductive compound from 0.2 to 1.5 % by weight of the total composition of the membrane. Said invention can be used to determine the lithium ion concentration of a fluid, such as a primary fluid for a pressurized water reactor in a nuclear power plant.
L'invention concerne une membrane sélective des ions lithium, comprenant un support polymère, un plastifiant, un composé conducteur ainsi qu'un composé ionophore spécifique des ions lithium. L'invention consiste en ce que ledit composé ionophore est le dibenzyl-14-couronne-4 et ses dérivés, et représente entre 0,5 et 3 % en poids de la composition totale de la membrane, le support polymère représentant 25 à 30% en poids de la composition totale de la membrane, le plastifiant de 65 à 72% en poids de la composition totale de la membrane et le composé conducteur de 0,2 à 1,5 % en poids de la composition totale de la membrane. Application à la détermination de la concentration en ions lithium d'un fluide, tel qu'un fluide primaire de réacteur à eau pressurisée de centrale nucléaire.
