MA-202U (Macroporous Strong-Base Anion Exchange Resin)

Uranium ndi radionuclide, nthawi zambiri imachitika m'madzi apansi kuposa madzi apamtunda, ndipo nthawi zambiri

amapezeka pamodzi ndi radium. Kuchepetsa madzi ovuta kungafune chithandizo kuti kuchotsedwa kwa uranium ndi radium.

Uranium imapezeka m'madzi momwe uranyl ion, UO22 +, imapangidwira pamaso pa oxygen. Pa pH pamwambapa sikisi, uranium imapezeka m'madzi abwino makamaka ngati uranyl carbonate complex. Mtundu wa uraniumwu umakondana kwambiri ndi utomoni wamphamvu wa anion.

Ndondomeko yoyandikana ndi ma resin olimba amchere a anion amitundu yodziwika m'madzi akumwa akuwonetsa uranium pamwamba pamndandanda:

Kusintha

Pofuna kubwezeretsanso uranyl carbonate ndikofunikira kuti kuchuluka kwa zosinthika pabedi la resin kukhale kokwanira mokwanira kuti muchepetse kapena kuchepetsa zoperekazo kuti zikhale zovomerezeka ndikugwiritsa ntchito nthawi yokwanira yobwezeretsanso komanso nthawi yolumikizirana. Sodium chloride ndiwowonjezereka kwambiri.

Kukhazikika pamwamba pa 10% NaCl, pamiyeso yobwezeretsa ya 14 mpaka 15 lbs. pa cu. Ft. ndikwanira kutsimikizira bwino kuposa 90% ya uranium yochotseredwa kudzera muntchito. Mlingowu upititsa osachepera 50% ya uranium yosungidwa kuchokera mu utomoni. Kutulutsa kumakhalabe kotsika kudzera munthawi yantchito ngakhale osasinthiratu chifukwa chakusankha kwakukulu munthawi yantchito. Zotayikira sizikhala ndi magawo obwezeretsanso a 15 lbs. wa sodium chloride pa cu. Ft. pamlingo wa 10% kapena kupitilira apo wokhala ndi nthawi yolumikizana yochepera mphindi 10 pakusintha.

Chitetezo ndi Kusamalira

Zinyalala zosachiritsika zochotsa ureniamu ndi mtundu wina wa uranium ndipo uyenera kutayidwa bwino. Kwa mwininyumba, yankho lomwe lagwiritsidwa ntchito nthawi zambiri limatulutsidwa chimodzimodzi momwe softener brine amatulutsidwira, kuchuluka kwa uranium yomwe ikufika pomwe ikufikidwako ndiyofanana kaya mulibe uranium yomwe ilipo. Komabe, ndikofunikira kuwunika malamulidwe a malo omwe mwapatsidwa.

Kutaya kwa utomoni wodzaza ndi uranium kuyenera kuganizira kuchuluka kwa ma radioactivity omwe amapezeka munyuzipepala.

Dipatimenti Yoyendetsa ku United States imayang'anira kayendedwe ndi kayendedwe ka zinyalala zotsika kwambiri. Uranium ndi yopanda poizoni ndipo ili ndi milingo yayikulu kuposa radium. Mulingo wonenedwa wa uranium ndi ma pico 2,000 mazana awiri pagalamu iliyonse yazofalitsa.

Zoyembekeza zomwe zitha kuwerengedwa zitha kuwerengedwa ndi omwe akupatsani ma resin omwe amakupatsani. Kugwiritsa ntchito kamodzi kokha kumatha kufikira voliyumu yopitilira 100,000 (BV), pomwe ntchito zomwe zingasinthidwe zitha kukhala pafupifupi 40,000 mpaka 50,000 BV. Ngakhale zili zoyeserera kuyendetsa utomoni wautali momwe ungathere pamafunso omwe adachitika kamodzi, kulingalira kuyenera kuperekedwa ku kuchuluka kwa uranium komwe kusonkhanitsidwa komanso zomwe zidzachitike pambuyo pake.
