MA-202U (Macroporous Strong-Base Anion Exchange Resin)
Uranium yog radionuclide, feem ntau yuav tshwm sim hauv cov av hauv av dua li cov dej saum npoo av, thiab feem ntau
pom ua ke nrog radium. Kev txo qis ntawm cov teeb meem dej yuav xav tau kev kho kom tshem tawm ob qho uranium thiab radium.
Uranium feem ntau muaj nyob hauv dej raws li uranyl ion, UO22+, tsim thaum muaj cov pa. Ntawm pH siab dua rau rau, uranium muaj nyob hauv cov dej muaj peev xwm feem ntau yog uranyl carbonate complex. Daim ntawv no ntawm uranium muaj qhov zoo sib xws rau cov hauv paus ruaj khov anion resins.
Qhov kev txiav txim siab txheeb ze ntawm kev sib raug zoo ntawm cov hauv paus ruaj khov anion resins rau qee qhov ions hauv cov dej haus qhia uranium nyob rau saum toj ntawm cov npe:

Rov tsim dua tshiab
Txhawm rau rov tsim dua cov uranyl carbonate nws yog ib qho tseem ceeb uas cov concentration ntawm cov neeg tsim dua tshiab ntawm lub txaj txaj kom txaus txaus kom thim rov qab lossis txo cov txheeb ze sib raug zoo mus rau qib uas tau lees paub thiab siv txaus tsim dua tshiab thiab tiv tauj lub sijhawm. Sodium chloride yog feem ntau tsim dua tshiab.
Cov ntsiab lus siab dua 10% NaCl, ntawm qib rov tsim dua ntawm 14 txog 15 lbs. rau cu. ft. yog txaus los pov hwm zoo dua li 90% tshem tawm uranium los ntawm kev ua haujlwm. Qhov koob tshuaj no yuav tshem tawm tsawg kawg 50% ntawm cov uranium sau los ntawm cov cob. Cov dej xau yuav nyob qis qis los ntawm cov kev pabcuam mus los txawm tias tsis muaj kev rov tsim dua tshiab vim tias muaj kev xaiv ntau heev thaum lub sijhawm pabcuam. Cov dej xau yog qhov tseem ceeb nil rau qib kev tsim dua tshiab ntawm 15 lbs. ntawm sodium chloride ib cu. ft. ntawm qhov sib luag ntawm 10% lossis siab dua nrog lub sijhawm sib cuag yam tsawg kawg ntawm 10 feeb thaum tsim kho.

Kev Nyab Xeeb thiab Kev Ua Haujlwm
Kev rov tsim dua cov pov tseg los ntawm cov txheej txheem tshem tawm cov uranium yog daim ntawv ntawm cov uranium thiab yuav tsum tau muab pov tseg kom raug. Rau tus tswv tsev, kev siv tshuaj feem ntau yog tso tawm tib txoj kev ua kom cov dej qab ntsev ua kom mos, cov nuj nqis ntawm cov uranium mus txog qhov chaw pov tseg yog zoo ib yam txawm tias tsis muaj chav tshem tawm uranium nyob hauv qhov chaw. Txawm li cas los xij, nws yog qhov tsim nyog los tshuaj xyuas cov cai hauv ib cheeb tsam uas tau muab.
Kev pov tseg ntawm cov tshuaj uranium-laden yuav tsum coj mus rau hauv tus account tus nqi hluav taws xob muaj nyob hauv xov xwm.
Tsoomfwv Meskas Lub Tsev Haujlwm Saib Xyuas Kev Thauj Mus Los tswj hwm kev thauj mus los thiab tuav cov khoom pov tseg cov pa hluav taws xob qis. Uranium tsis muaj tshuaj lom thiab yog li muaj qib tso cai ntau dua li radium. Cov qib qhia rau uranium yog 2,000 picoCuries ib gram ntawm kev tshaj xov xwm.
Kev kwv yees kev nkag tau tuaj yeem suav los ntawm koj cov khoom siv pauv pauv ion. Ib zaug-dhau daim ntawv thov tuaj yeem mus txog qhov theoretical throughput ntau ntau dua 100,000 lub txaj tag nrho (BV), thaum kev pabcuam mus los ntawm kev pabcuam tsim kho tshiab tuaj yeem nyob ib puag ncig 40,000 txog 50,000 BV. Txawm hais tias nws yog kev ntxias kom siv cov kua nplaum ntev li ntev tau ntawm cov ntawv thov ib zaug, kev txiav txim siab yuav tsum tau muab rau tag nrho cov nyiaj uranium sau thiab cov teeb meem tom ntej pov tseg.
