I-MA-202U (iMacroporous Strong-Base Anion Exchange Resin)
Iuranium iradionuclide, kunokwenzeka ukuba yenzeke emanzini angaphantsi komhlaba, kwaye ihlala ikhona
ifunyenwe kunye ne-radium. Ukuncitshiswa kwengxaki yamanzi kunokufuna unyango lokususa zombini i-uranium kunye ne-radium.
I-Uranium ihlala ikhona emanzini njenge-uranyl ion, UO22 +, eyenziwe phambi kweoksijini. Kwi-pH ngaphezulu kwesithandathu, i-uranium ikhona emanzini aselwayo ikakhulu njenge-uranyl carbonate complex. Olu hlobo lwe-uranium lunobudlelwane obumangalisayo bee-resion ze-anion ezomeleleyo.
Umyalelo osondeleyo wobumbano lwee-anion resins ezomeleleyo ze-ion eziqhelekileyo emanzini okusela zibonisa i-uranium ephezulu kuluhlu:
Iimpawu ezibonakalayo zomzimba kunye neMichiza
| Ulwakhiwo lweMatrix yePolymer | Isitayile esiNxibeleleneyo neDVB |
| Uhlobo lomzimba kunye nokuBonakala | Opaque amaso |
| Ukubala konke kweBead | 95% imiz. |
| Amaqela aSebenzayo | CN2-N + = (CH3)3) |
| Ifom ye-Ionic, njengoko ithunyelwe | SO4 |
| Amandla okuTshintshiselana ewonke, SO4- ifom, emanzi, yevolumetric | 1.10 eq / l imiz. |
| Ukugcinwa kokufuma, i-CL- ifom | 50-60% |
| 0.71-1.60 mm> 95% | |
| Ukudumba CL-→ OH- | 10% ubuninzi |
| Amandla | Ngaphantsi kwe 95% |
Ukuhlaziywa
Ukulungiselela ukuvuselela i-uranyl carbonate kubalulekile ukuba uxinizelelo lwento ehlaziyayo ebhedini ukuba ibuyele umva okanye inciphise izinto ezinxulumene noko kwinqanaba elamkelekileyo kunye nokusebenzisa ixesha lokuhlaziya kunye nexesha lokunxibelelana. Isodium chloride yeyona nto ihlaziya ngokutsha.
Uxinzelelo ngaphezulu kwe-10% NaCl, kumanqanaba ahlaziyayo e-14 ukuya kwi-15 lbs. ngekota nganye. Ft kwanele ukuqinisekisa ngcono ngaphandle kwe-90% yokususwa kwe-uranium ngomjikelo wokusebenza. Le dosi iya kuphakamisa ubuncinci i-50% ye-uranium eqokelelweyo evela kwi-resin. Ukuvuza kuya kuhlala kusezantsi ngemijikelo yenkonzo nokuba ngaphandle kohlaziyo olupheleleyo ngenxa yokukhetha okuphezulu kakhulu ngexesha lomjikelo wenkonzo. Ukuvuza akubalulekanga kumanqanaba okuhlaziya kwakhona ee-15 lbs. Isodiyam chloride nganye cu. Ft.kugxininiso lwe-10% okanye ngaphezulu ubuncinci bexesha lokunxibelelana ubuncinci imizuzu eyi-10 ngexesha lokuvuselelwa.
Ukusebenza kokungafaniyo kwetyuwa:
Inqanaba lokuhlaziya - Malunga ne-22 lbs. ngekota nganye. Ft. yohlobo 1 Gel Anion Resin.

Ukhuseleko nokusingatha
Inkunkuma evuselelekayo evela kwinkqubo yokususa i-uranium yifomathi ye-uranium kwaye kufuneka ilahlwe ngokufanelekileyo. Kumninikhaya, isisombululo esisetyenzisiweyo sihlala sikhutshwa ngendlela efanayo nesithambisi esikhululwayo, isixa semali ye-uranium efikelela kwindawo yokulahla iyafana nokuba iyunithi yokususa i-uranium ikho. Okwangoku, kuyimfuneko ukujonga imigaqo yendawo ethile.
Ukulahlwa kwe-resin egcwele i-uranium kufuneka kuthathelwe ingqalelo inani le-radioactivity ekhoyo kumajelo eendaba.
ISebe lezoThutho laseMelika lilawula ukuthuthwa nokuphathwa kwenkunkuma eqhumayo yenqanaba elisezantsi. Iuranium ayinetyhefu encinci kwaye ke inamazinga aphezulu avumelekileyo kune-radium. Inqanaba elichaziweyo le-uranium ngamawaka amabini eepico ngegramu yemithombo yeendaba.
Iziphumo ezilindelweyo zinokubalwa ngumthengisi wakho we-ion resin. Ukusetyenziswa kwezicelo kunokufikelela kwimilinganiselo yokuhamba kwezinto ezinkulu kakhulu kuneebhedi eziyi-100,000 (BV), ngelixa iijikelezo zenkonzo kwiinkonzo ezingenakuhlaziywa zingaba ngama-40,000 ukuya kuma-50,000 BV. Nangona kulinga ukuqhuba i-resin ixesha elide kangangoko kunokwenzeka kwizicelo ezenziwa kube kanye, kufuneka kuthathelwe ingqalelo inani elipheleleyo le-uranium eqokelelweyo kunye nemicimbi yokulahla elandelayo.
