MA-202U (Macroporous Yakasimba-Base Anion Shanduro Resin)
Uranium iradionuclide, inowanzoitika mumvura yepasi pane pamusoro pemvura, uye kazhinji
yakawanikwa pamwechete neradium. Kudzikisira kwedambudziko remvura kunogona kuda kurapwa kwekubviswa kweiri uranium uye radium.
Uranium inowanzovapo mumvura sezvo uranyl ion, UO22 +, yakaumbwa pamberi pe oxygen. Pa pH pamusoro pematanhatu, uranium inowanikwa mumvura inotonhorera zvakanyanya seiyo uranyl carbonate yakaoma. Iyi fomu yeuranium ine hukama hwakakura hweakasimba base anion resins.
Kurongeka kwehukama hwehukama hwakasimba anion resin yemamwe maon ione mukunwa mvura inoratidza uranium pamusoro pechinyorwa:

Kuberekwa patsva
Kuti umutsiridze uranyl carbonate zvakakosha kuti iko kusunganidzwa kweanodzokorodza pamubhedha weRein kuve kwakaringana kukwirisa kana kudzikamisa hama dzakabatana kumatanho anogamuchirwa uye kushandisa yakakwana yekuzvidzora uye yekubata nguva. Sodium chloride ndiyo inowanzo regenerant.
Kusungirirwa pamusoro pe10% NaCl, pamatanho ekuvandudza e14 kusvika 15 lbs. pa cu. Ft. inokwana inishuwarenzi zvirinani pane 90% kubviswa kweuanium kuburikidza neiyo inoshanda kutenderera. Iyi dosage inokwenenzvera kanokwana 50% yeiyo yakaunganidzwa uranium kubva muresin. Kuvuza kucharamba kwakaderera kuburikidza nemasevhisi ebasa kunyangwe pasina kumutsiridzwa kwakazara nekuda kwekusarudzika kwakanyanya panguva yekutenderera kwebasa. Zvinodonhedza zvakanyanyisa nil zvekumutsiridza mwero we15 lbs. ye sodium chloride per cu.

Kudzivirirwa uye Kubata
Regenerant marara kubva muiyo uranium yekubvisa sisitimu inzira yakasunganidzwa yeiyo uranium uye inofanira kuraswa zvakanaka. Kune muridzi wemba, mhinduro yakashandiswa inowanzo buritswa nenzira imwecheteyo softener brine inoburitswa, iyo mambure huwandu hweiyo uranium inosvika panzvimbo yekurasa yakafanana kana kuti kana kwete urani yekubvisa yuniti iri munzvimbo. Zvakadaro, izvo zvinodikanwa kuti utarise iyo mirau yenzvimbo yakapihwa.
Kuraswa kweuranium-yakatakurirwa resin inofanirwa kutarisisa huwandu hweradioactivity irimo munhau.
Dhipatimendi rekutakura reU.S. rinotungamira kutakurwa nekubatwa kwemarara epasi ane mwero. Uranium haina chepfu uye saka ine yakakwira inotenderwa nhanho kupfuura radium. Iyo yakataurwa chikamu cheuranium is 2,000 picoCuries per gram of media.
Mafungidziro anotarisirwa anogona kuverengerwa neyako ion resin mutengesi. Kamwe-kubudikidza nekushandisa kunogona kusvika muzvinyorwa zvekuverenga zvakanyanya kupfuura zviuru zana zvemubhedha (BV), nepo masekero ebasa pane basa rinogadziriswazve anogona kunge ari makumi mana kusvika makumi mashanu eBV. Kunyangwe iri kuyedza kumhanyisa iyo resini sekureba sezvinobvira pane kamwe-kuburikidza nekushandisa, kutarisisa kunofanirwa kupihwa kune huwandu hwakazara weuranium yakaunganidzwa uye zvinotevera nyaya dzekurasa.
