I-MA-202U (iMacroporous Strong-Base Anion Exchange Resin)
I-uranium yi-radionuclide, kungenzeka kakhulu ukuthi yenzeke emanzini angaphansi komhlaba kunamanzi angaphezulu, futhi imvamisa
itholakale kanye ne-radium. Ukuncishiswa kwamanzi anenkinga kungadinga ukwelashwa ukuze kususwe i-uranium ne-radium.
I-Uranium uqobo ikhona emanzini njengoba i-uranyl ion, UO22 +, yakhiwa kukhona umoya-mpilo. Ku-pH ngenhla kwesithupha, i-uranium ikhona emanzini okuphuzwa ngokuyinhloko njenge-uranyl carbonate complex. Leli fomu le-uranium linobudlelwano obukhulu bezinhlaka ze-anion ezinamandla.
I-oda elihlobene lokusondelana kwama-resin anion base anamandla ama-ion athile emanzini okuphuza abonisa i-uranium phezulu kohlu:
Izici ezijwayelekile zomzimba nezamakhemikhali
| Isakhiwo sePolymer Matrix | I-Styrene Crosslinked ne-DVB |
| Ifomu Lomzimba nokubukeka | Ubuhlalu Opaque |
| Ukubala okuphelele kobuhlalu | 95% min. |
| Amaqembu asebenzayo | CN2-N + = (CH3)3) |
| Ifomu le-Ionic, njengoba lithunyelwe | SO4 |
| Ingqikithi Yokushintshaniswa Kwamakhono, SO4- ifomu, imanzi, ivolumu | 1.10 eq / l iminithi. |
| Ukugcinwa Komswakama, CL- ifomu | 50-60% |
| 0.71-1.60 mm> 95% | |
| Ukuvuvukala CL-→ OH- | 10% ubuningi |
| Amandla | Hhayi ngaphansi kuka-95% |
Ukuvuselelwa
Ukuze kuvuselelwe i-uranyl carbonate kubalulekile ukuthi ukugxila kokuvuselelayo embhedeni we-resin kube phezulu ngokwanele ukubuyisela emuva noma ukunciphisa ama-affinities ahlobene kumazinga amukelekile nokusebenzisa isikhathi esanele sokuvuselela kanye nesikhathi sokuxhumana. I-sodium chloride iyona evame kakhulu ukuvuselelwa.
Ukuhlushwa okungaphezu kwe-10% NaCl, emazingeni avuselelayo we-14 kuye ku-15 lbs. nge-cu ngayinye. I-ft. yanele ukuvikela kangcono kunokukhishwa kwe-uranium okungu-90% ngomjikelezo wokusebenza. Lo mthamo uzokhipha okungenani u-50% we-uranium eqoqwe kusuka ku-resin. Ukuvuza kuzohlala kuphansi ngemijikelezo yesevisi ngaphandle kokuvuselelwa okuphelele ngenxa yokukhethwa okuphezulu kakhulu phakathi nomjikelezo wesevisi. Ukuvuza empeleni akukho emazingeni wokuvuselela ama-15 lbs. kwe-sodium chloride nge-cu ngayinye. Ft. ekugxileni kwe-10% noma ngaphezulu ngesikhathi esiphansi sokuxhumana okungenani imizuzu eyi-10 ngesikhathi sokuvuselelwa.
Ukusebenza kahle kokugxila kasawoti okuhlukahlukene:

Ukuphepha nokuphatha
Imfucuza evuselelekayo evela ohlelweni lokususa i-uranium iyindlela egxilile ye-uranium futhi kufanele ilahlwe ngokufanele. Kumninikhaya, isixazululo esisetshenzisiwe sikhishwa ngendlela efanayo ne-softener brine ekhishwayo, inani eliphelele le-uranium elifinyelela lapho kulahlwa khona liyafana noma ngabe iyunithi yokususa i-uranium isendaweni. Noma kunjalo, kuyadingeka ukuhlola imithethonqubo yendawo ethile oyinikiwe.
Ukulahlwa kwe-resin egcwele i-uranium kufanele kubhekele inani le-radioactivity ekhona kwabezindaba.
Umnyango Wezokuthutha wase-US ulawula ukuthuthwa nokuphathwa kwemfucumfucu enemisebe esezingeni eliphansi. I-uranium ayinabuthi kangako futhi inamazinga aphakeme kakhulu avunyelwe kune-radium. Izinga elibikiwe le-uranium liyi-2 000 picoCuries ngegramu yemidiya.
Izindlela ezilindelwe ezingabalwa ngumhlinzeki wakho we-resin resin. Izicelo ezenziwa kanye kuphela zingafinyelela kumanani wokufunda okuthe xaxa amakhulu kakhulu kunamanani embhede angama-100,000 (BV), ngenkathi imijikelezo yesevisi esevisi evuselelekayo ingaba cishe ngama-40,000 kuye kuma-50,000 BV. Yize kulinga ukusebenzisa i-resin isikhathi eside ngangokunokwenzeka kuzicelo ezenziwa kanye, kufanele kubhekwe inani eliphelele le-uranium eqoqiwe kanye nezinkinga zokulahlwa okulandelayo.
