Background
Poyerekeza ndi nthaka, zinthu za uranium m'madzi a m'nyanja zimatha kufotokozedwa ngati "zosatha". Malo osungiramo uranium m’madzi a m’nyanja ndi pafupifupi matani 4.5 biliyoni, omwe ndi ofanana kuŵirikiza ka 1,000 nkhokwe za migodi ya uranium pamtunda. Ndi kupita patsogolo kosalekeza kwaukadaulo wochotsa uranium m'madzi a m'nyanja, ngati zida za uranium m'madzi a m'nyanja zitha kugwiritsidwa ntchito bwino m'tsogolomu, zidzakhala zokwanira kuwonetsetsa kuti mphamvu za nyukiliya zikukhazikika ndikukwaniritsa zofuna za anthu. M'mbuyomu, ofufuza a Oak Ridge National Laboratory ndi Lawrence Berkeley National Laboratory ku United States adapeza mtundu watsopano wa madzi a m'nyanja a uranium sorbent omwe amatha kupangidwanso ndikugwiritsidwanso ntchito mu njira yochepetsera ya carbonate. Ndi kuwongolera kosalekeza kwa kagwiritsidwe ntchito ka zinthu zochotsa uranium, vuto la nkhokwe zaukadaulo zosakwanira zochotsa uranium m'madzi a m'nyanja lakula kwambiri.
Ofufuza pa yunivesite ya Hainan ku China apanga siponji yapadera yomwe ingagwiritsidwe ntchito poyeretsa zinyalala za nyukiliya, ndipo chofunika kwambiri, ikhoza kugwiritsidwanso ntchito kuchotsa zinthu za uranium m'madzi a m'nyanja. Chithovu chosinthidwa cha melamine chopangidwa ndi thovu la melamine, zinthuzo zimagwiritsidwa ntchito kwambiri poyeretsa siponji m'nyumba, kuchepetsa phokoso lanyumba, kutchinjiriza kwa njanji, zida zamagalimoto zamagalimoto ndi magawo ena. Chithovu cha melamine chimakhala ndi kuchuluka kwa maselo otseguka a 99%, ndipo kuchuluka kwa mayamwidwe amadzi/madzi kumachulukitsa ka 90 kulemera kwake komwe.
Chithovu cha melamine chimaviikidwa mu yankho lomwe lili ndi mankhwala omwe amamangiriza mosavuta ku uranium ndi zouma mpweya. Mapangidwe amkati a siponji amasiya filimu ya mankhwala. Siponjiyo itamizidwa m’madzi a m’nyanja matani asanu kwa milungu isanu ndi itatu, inatenga pafupifupi mamiligalamu 1.9 a uranium pa gramu imodzi, yomwe ndi yofanana ndi kuchuluka kwa njira zina zopezera uranium m’nyanja. Poyerekeza ndi njira zina zochotsera uranium pogwiritsa ntchito pulasitiki, masiponji a melamine amatha kuwonongeka kwambiri ndipo motero sakonda chilengedwe.
Pambuyo poti thovu la melamine losinthidwalo latenga uranium, limatenga mtundu wachikasu womwe chinthuchi chili nawo. Potsuka, uranium imatha kuchotsedwa ngati mafuta opangira magetsi a nyukiliya. Kenako siponji imatha kuyikidwanso m'nyanja. Siponjiyo imataya mphamvu zake zina panjira iliyonse yobwezeretsanso zinthu chifukwa imamanga zinthu zina zomwe zimakhala zovuta kuyeretsa, ndipo izi zimapangitsa kuti pakhale vuto pakugwiritsa ntchito zinthu zambiri. Njirayi pakadali pano ndi yokwera mtengo kuposa migodi ya uranium, koma pamene mcherewo watha, zinthu zochepa za siponji zingagwiritsidwe ntchito, zomwe zingachotsedwe m'nyanja. Pezani mafuta ambiri a nyukiliya, omwe amagwira ntchito yofunika kwambiri pakutulutsa uranium m'madzi a m'nyanja.
Pakalipano, njira yosavuta yopezera uranium ndikuyamba migodi kuchokera ku miyala yapadziko lapansi. Iyenera kudutsa njira zovuta kwambiri, kuphatikizapo kufufuza, migodi, kupindula, leaching, smelting, kuyenga ndi njira zina. Ngati ukadaulo wina wochotsa uranium m'madzi a m'nyanja ungapangidwe, ukhoza kuwongoleredwa ndikuwongolera kuti uzindikire kuwongolera kwamphamvu kwapanyanja. Panthawi imodzimodziyo, kafukufuku wamakono ndi chitukuko cha kuchotsa uranium m'madzi a m'nyanja ayenera kuyang'anitsitsa kuphatikiza ndi mafakitale okhwima monga kuchotsa madzi a m'nyanja ndi kuchotsa mchere wa m'nyanja, kuti azindikire kugwiritsa ntchito bwino zinthu za m'nyanja.
SINOYQX ipereka zida zaulere za thovu la melamine m'mabungwe akuluakulu ofufuza asayansi pofufuza ndi kupanga zida zosinthidwa za melamine thovu la uranium.
