In het afgelopen jaar zijn diverse technisch vervaardigde nanomaterialen en membranen ontwikkeld om te verwijderen van gevaarlijke radioactieve metalen en zware metalen in water op basis van hun specifieke functionaliteit in adsorptie technieken25,26,, 27 , 28 , 29 , 30 , 31 , <su...

Voor decennia, is enorme hoeveelheid radioactieve vloeibare afvalstoffen gegenereerd door medische instituten, onderzoeksfaciliteiten en nucleaire reactoren. Deze verontreinigende stoffen zijn vaak een tastbaar bedreiging voor milieu en gezondheid van de mens1,2,3. Vooral, wordt radioactief jodium erkend als één van de meest gevaarlijke elementen van kerncentrale ongevallen. Bijvoorbeeld, een milieu verslag over de Fukushima en in Tsjernobyl nucleaire reactor aangetoond dat de hoeveelheid radioactief iodines met inbegrip van 131vrijgegeven I (t-1/2 = 8.02 dagen) en 129ik (t-1/2 = 15,7 miljoen jaar) voor het milieu was groter dan die van andere radionucliden4,5. In het bijzonder, resulteerde de blootstelling van deze radio-isotopen in hoge opname en verrijking in de menselijke schildklier6. Vrijgegeven radioactieve iodines veroorzaken bovendien ernstige verontreiniging van bodem, zeewater en grondwater vanwege hun hoge oplosbaarheid in water. Dus een heleboel sanering processen met behulp van verschillende anorganische en organische adsorbents zijn onderzocht om vast te leggen van radioactieve iodines in waterige afvalstoffen7,,8,,9,10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20. Hoewel uitgebreide inspanningen voor de ontwikkeling van geavanceerde adsorberende systemen hebben besteed, de oprichting van een methode van de decontaminatie tonen bevredigende prestaties onder voortdurende in-flow voorwaarde was zeer beperkt. Onlangs meldden we een roman ontzilting proces tonen goede verwijdering efficiëntie, ion-selectiviteit, duurzaamheid en hergebruik door het gebruik van hybride nano-composiet materialen gemaakt van gouden nanoparticle (AuNPs)21,22 , 23. onder hen, gouden nanoparticle-embedded celluloseacetaat membranen (Au-CAM) vergemakkelijkt hoogefficiënte ontzilting van jodide-ionen onder een continue-stroom systeem vergeleken met die van bestaande adsorberende materialen. Bovendien kon de hele procedure worden afgewerkt in een korte tijd, die een ander voordeel voor de behandeling van nucleair afval gegenereerd door na gebruik in de medische en industriële toepassingen was. Het algemene doel van dit manuscript is bedoeld als een stapsgewijze protocol voor de bereiding van Au-CAM24. We tonen ook een snelle en gemakkelijke filtratie proces voor het vastleggen van de ion-selectieve van radioactief jodium met behulp van de gemanipuleerde samengestelde membranen. Het gedetailleerd protocol in dit verslag biedt een nuttige toepassing van nanomaterialen op het gebied van het onderzoek van milieukunde.

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

Hier tonen we een gedetailleerd protocol voor de bereiding van nanomaterialen-embedded samengestelde membranen en de toepassing ervan voor de efficiënte en ion-selectieve verwijdering van radioactieve iodines. Met behulp van citraat-gestabiliseerde gouden nanodeeltjes (gemiddelde diameter: 13 nm) en celluloseacetaat membranen, goud nanoparticle-embedded celluloseacetaat membranen (Au-CAM) hebben gemakkelijk zijn vervaardigd. De nano-adsorbents op Au-CAM waren zeer stabiel in het bijzijn van de hoge concentratie van anorganische zouten en organische moleculen. De jodide-ionen in waterige oplossingen kunnen snel worden onderschept door deze gemanipuleerde membraan. Door middel van een filtratie proces met behulp van een Au-CAM met filter eenheid, uitstekende verwijdering efficiëntie (> 99%) zo goed als ion-selectieve ontzilting resultaat werd bereikt in een korte tijd. Bovendien, Au-CAM verstrekt goede herbruikbaarheid zonder significante afname van de prestaties. Deze resultaten voorgesteld dat de huidige technologie met behulp van de gemanipuleerde hybride membraan zal een veelbelovend proces voor de grootschalige ontsmetting van radioactief jodium van vloeibaar afval.

We hebben eenvoudige methoden voor de fabrikatie van Au-CAM met citraat-gestabiliseerde AuNPs en celluloseacetaat membraan (Figuur 1een) aangetoond. Het oppervlak van de Au-CAM werd waargenomen door SEM waaruit bleek dat de nanomaterialen stabiel zijn opgenomen op de cellulose nanofibers (Figuur 2). De nanodeeltjes opgesloten op het membraan stabiel waren opgelopen en werden niet vrijgegeven van het membraan door...
