Dans les récentes années, divers nanomatériaux et les membranes ont été développés pour éliminer les métaux radioactifs dangereux et les métaux lourds dans l’eau fondé sur leurs fonctionnalités propres à l’adsorption des techniques25,26, 27 , 28 , 29 , 30 , 31 , <...

Depuis plusieurs décennies, une quantité énorme de déchets liquides radioactifs a été générée par les réacteurs nucléaires, installations de recherche et instituts médicaux. Ces polluants ont souvent été une menace palpable à l’environnement et la santé humaine1,2,3. En particulier, l’iode radioactif est reconnu comme un des éléments plus dangereux des accidents de la centrale nucléaire. Par exemple, un environnement rapport sur la Fukushima et de Tchernobyl réacteur nucléaire ont démontré que la quantité de libérée iodes radioactifs dont 131I (t1/2 = 8,02 jours) et 129je (t1/2 = 15,7 millions d’années) dans l’environnement était plus gros que ceux d’autres radionucléides4,5. En particulier, l’exposition de ces radio-isotopes abouti à haute absorption et enrichissement dans la thyroïde humaine6. En outre, les iodes radioactifs libérés peuvent causer grave contamination des sols, l’eau de mer et l’eau souterraine en raison de leur grande solubilité dans l’eau. Par conséquent, un grand nombre de processus d’assainissement à l’aide de différents adsorbants inorganiques et organiques ont été étudiés pour capturer les iodes radioactifs déchets aqueux7,8,9,10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20. bien que des efforts considérables ont été consacrés au développement de systèmes avancés de l’adsorbants, la mise en place d’une méthode de décontamination montrant des performances satisfaisantes sous condition de flux continue était très limité. Récemment, nous avons rapporté un procédé de dessalement roman montrant la bonne efficacité, la sélectivité ionique, durabilité et réutilisabilité en utilisant des matériaux nano-composite hybride de nanoparticule or (AuNPs)21,22 , 23. parmi eux, membranes d’acétate de cellulose de nanoparticules-embedded or (UA-CAM) a facilité le dessalement très efficace des ions iodure sous un système de flux continu, comparé à celles des matériaux adsorbants existants. En outre, l’ensemble de la procédure pourrait être fini en peu de temps, qui était un autre avantage pour le traitement des déchets nucléaires produit de l’utilisation dans des applications médicales et industrielles. L’objectif global de ce manuscrit est de fournir un protocole étape par étape pour la préparation de l’UA-CAM24. Nous démontrons également un procédé de filtration rapide et commode pour la capture sélective des ions d’iode radioactif en utilisant les membranes composites machinés. Le protocole détaillé dans le présent rapport offre une application utile de nanomatériaux dans le domaine de la recherche des sciences de l’environnement.

an efficient method for selective desalination of radioactive iodine anions by using gold nanoparticles-embedded membrane filter

Ici, nous démontrons un protocole de détail pour la préparation des membranes composites nanomatériaux incorporé et son application à l’élimination efficace et sélectives des iodes radioactifs. En utilisant des nanoparticules d’or citrate-stabilisé (diamètre moyen : 13 nm) et les membranes d’acétate de cellulose, or membranes d’acétate de cellulose NANOPARTICULE incorporé (UA-CAM) ont facilement été fabriquées. Les nano-adsorbants sur UA-CAM ont été extrêmement stables en présence de forte concentration de sels inorganiques et de molécules organiques. Les ions iodure dans des solutions aqueuses pourraient rapidement être capturées par cette membrane machinée. Grâce à un procédé de filtration à l’aide d’une unité de filtration contenant UA-CAM, excellente efficacité (> 99 %) aussi bien que sélectives dessalement résultat a été obtenu en peu de temps. En outre, Au-CAM fourni bonne réutilisation sans diminution significative de ses performances. Ces résultats suggèrent que la technologie actuelle en utilisant la membrane machiné hybride sera un processus prometteur pour la décontamination à grande échelle d’iode radioactif de déchets liquides.

Nous avons démontré des méthodes simples pour la confection d’UA-CAM à l’aide de stabilisé citrate AuNPs et acétate de cellulose membrane (Figure 1a). La surface d’UA-CAM a été observée par SEM qui a montré que les nanomatériaux ont été incorporés stablement sur les nanofibres de cellulose (Figure 2). Les nanoparticules incarcérés sur la membrane se sont maintenues de façon stable et n’é...
