Kuchotsera, kukonzekera ndi kusungidwa kotetezeka kwaGadolinium oxide (GD₂O₃)ndi mbali zofunika za kuchitika kwanthawi yayitali padziko lapansi. Izi ndi kufotokoza mwatsatanetsatane:
-, njira yodulitsira ya gadolinium oxide
Gadolinium oxide nthawi zambiri amatulutsidwa kuchokera ku ORERE WOYERA WOYAMBA Njira yowonjezera imaphatikizapo izi:
1.
Ored Orter Ore amawola ndi acid kapena njira ya alkaline.
Njira ya Aciri: Chitirani ore ndi Sulfuric acid kapena hydrochloric acid kuti asinthe zinthu zamchere padziko lapansi.
Njira ya Alkaline: Gwiritsani ntchito sodium hydroxide kapena potaziyamu hydroxide kuti isungunuke kutentha kwambiri kuti musinthe zinthu zapansi za dziko lapansi mu hydroxides.
2.Kulekanira dziko lapansi:
Gawani Gadolinium kuchokera ku zosankha za dziko lapansi zosakanikirana ndi zosungunulira kapena kusinthitsa.
Solvent Eduction Njira: Gwiritsani ntchito organic sodic (monga ngati asfotyl phosphate) kuti asankha kuyamwa gadolinium.
Njira ya Ioni: Gwiritsani ntchito ion Kusinthana ma resin kuti muchepetse ma ayoli.
3.Kuthandiza GASOLinium:
Kudzera mwazomwe zimachitika kapena ion kusinthana, zinthu zina zapadziko lapansi komanso zodetsa zimachotsedwa kuti zitheke. Monga gadolinium chloride kapena gadolinium nitrate).
4.Kugonjera ku Gadolinium oxide:
Gadolinium yoyeretsedwa (monga gadolinium nitrate kapena gadolinium oxalate) amawerengedwa kutentha kwambiri kuti muwolake ndikupanga gadolinium oxide.
Chitsanzo: 2 GD (NO ₃ → GD₂O₃ + 6 NO₂ OI₂ O)
- Kukonzekera njira ya gadolinium oxide
1.Hhigh kutentha kukwana:
Calcine gadolinium mchere (monga gadolinium nitrate, gadolinium oxalate kapena gadolinium carbotete) kutentha (pamwamba pa 800 ° C) Kutentha kwa GASOLINE ndikupanga gadolinium oxide.
Ichi ndiye njira yokonzekera kwambiri komanso ndiyoyenera kupanga kwakukulu.
2. Njira ya 2.ydrothermal:
Gadolinium oxide nanoparticles amapangidwa ndi mchere wa gadolinium wokhala ndi macheza a alkalinine pansi pa kutentha kwambiri komanso kuthamanga kwa hydrothermil.
Njirayi imatha kukonzekeretsa kwambiri wa gadolinium oxide wokhala ndi tinthu tambiri.
3.Sol-gel:
Mchere wa Gadolinium umasakanikirana ndi organic morters (monga citric acid) kupanga sol, yomwe imapangidwa ndikugwedezeka, youma ndikuwerengera kuti ipeze gadolunium oxide.
Njirayi ndiyoyenera kukonzekeretsa nano-scale gadolinium oxide ufa.
, Malo osungirako gadolinium oxide
Gadolinium oxide ndi wokhazikika mu kutentha kwa firiji, koma malo osungira awa ayenera kudziwidwabe kuti atsimikizire kuti mwachita zachitetezo ndi zinthu:
1.Kutsimikizira:
Gadolinium oxide ali ndi hygrosopicity ndipo amayenera kusungidwa pamalo owuma kuti asayanjane ndi chinyezi.
Ndikulimbikitsidwa kugwiritsa ntchito chidebe chosindikizidwa ndikuwonjezera deta (monga silika gel).
2.
Gadolinium oxide amakhala osamala ndi kuwala, ndipo nthawi yayitali kuwunika kwamphamvu kungakhudze momwe akugwirira ntchito.
Iyenera kusungidwa pamalo abwino, amdima.
Kuyang'anira 3.
Kutentha kuyenera kulamulidwa mkati mwa kutentha kwa chipinda (15-25 ° C), kupewa malo apamwamba kapena otsika kutentha.
Kutentha kwakukulu kumatha kuyambitsa zosintha mu gadolinium oxide, ndipo kutentha kochepa kumayambitsa hygrosophicity.
4.Avoid ndi acid:
Gadolinium oxide ndi alkaline oxide ndipo adzachita zachiwawa.
Pewani ku zinthu za asidi nthawi yosungirako.
5.Prevent fumbi:
Mafuta a gadolinium oxibu amatha kukhumudwitsa thirakiti ndi khungu.
Gwiritsani ntchito zotsekemera zosindikizidwa mukamasunga ndikuvala zida zoteteza (monga masks ndi magolovesi) mukamagwira.
Iv. Kusamalitsa
1.Toxicity:Gadolinium oxide wokha ndi woopsa, koma fumbi limakhumudwitsa kupuma ndi khungu, motero kulumikizana mwachindunji kuyenera kupewedwa.
2.Waste kutaya:Kutaya Gadolinium oxide kuyenera kubwezeretsedwanso kapena kuthandizidwa mogwirizana ndi mankhwala owopsa othandiza kuti mupewe kuipitsa zachilengedwe.
