Ukukhishwa, ukulungiselela nokugcina okuphephile kweIGadinium Oxide (GD₂O₃)ziyizinto ezibalulekile zokucutshungulwa komhlaba okuvamile. Okulandelayo incazelo eningiliziwe:
一, indlela yokukhishwa kwe-gadinium oxide
IGadinium Oxide imvamisa ikhishwe kusuka emhlabathini ongafani no-ores oqukethe i-gadolimium, ama-ores ajwayelekile kubandakanya i-monazite ne-bastnäsite. Inqubo yokukhishwa ngokuyinhloko ifaka lezi zinyathelo ezilandelayo:
Ukuwohloka 1.
Umhlaba ongavamile uboshwe yi-acid noma i-alkaline indlela.
Indlela ye-Acid: phatha i-ore nge-sulfuric acid ehlanganisiwe noma i-hydrochloric acid ukuguqula izinto zomhlaba ezingandile zibe ngosawoti oncibilikayo.
Indlela ye-Alkalaline: Sebenzisa i-sodium hydroxide noma i-potassium hydroxide ukuncibilikisa i-ore ekushiseni okuphezulu ukuze uguqule izinto zomhlaba ezingandile zibe ama-hydroxides.
2.Rare Emhlabeni Ukwahlukana:
Hlukanisa i-Gadolimium kusuka ezixazululweni zomhlaba ezihlanganisiwe zomhlaba ngokukhishwa kwe-solvent noma i-ion Exchange.
Indlela Yokukhishwa Kwe-Solvent: Sebenzisa izixazululo ze-organic (ezifana ne-tributyl phosphate) ukuze ukhiphe i-gadolium ions.
Indlela yokushintshana nge-Ion: Sebenzisa i-ion Exchange Resin ukuhlukanisa ama-Gadolium Ion.
3.Ukuqinisekiswa kweGadinium:
Ngokukhipha okuningi noma ukushintshaniswa kwe-ini, ezinye izinto zomhlaba ezingandile kanye nokungcola zisuswa ukuthola amakhompiyutha e-gadolinium ahlanzekile (njengeGadinium Chloride noma iGadinium Nitrate noma iGadinium Nitrate).
4.CONTIVERSION DO CADOLIMIUM OXIde:
I-Gadolimium ehlanganisiwe ye-Gadolinium (efana neGadinium Nitrate noma iGadinium Oxalate) ibaliwe ekushiseni okuphezulu ukuze ibole kakhulu ukuze ibole futhi ikhiqize iGadinium oxide.
Isibonelo sokuphendula: 2 GD (No₃) ₃ → GD₂O₃ + 6 No₂ + 3/2 O₂
二, indlela yokulungiselela iGadinium Oxide
Indlela yokushisa yokushisa ye-1.aigh:
Usawoti weCaline Gadolinium (njengeGadinium Nitrate, Gadolimium Oxalate noma iGadinium Carbonate) ekushiseni okuphezulu (ngenhla kwama-800 ° C) ukubola futhi akhiqize iGadolinium oxide.
Le yindlela esetshenziswa kakhulu yokulungiselela futhi ilungele ukukhiqizwa okuphezulu.
Indlela engu-2.hydrothermal:
IGadinium Oxide Nanoparticles yenziwa ngokuphendula usawoti we-gaduinium ngezixazululo ze-alkaline ngaphansi kwezinga lokushisa eliphakeme kanye nezimo eziphakeme zengcindezi ye-hydrothermal.
Le ndlela ingalungisa ubumsulwa obuphezulu be-Axide nge-Uniform Particle usayizi.
Indlela ye-3.Sol-Gel:
Usawoti we-Gadolinium uxutshwe nabameleli be-organic (njenge-citric acid) ukwakha i-sol, esenziwa yagcwala, yomisiwe futhi yabuna ekutholeni iGadolinium oxide.
Le ndlela ilungele ukulungiselela i-nano-scale gadolinium oxide powder.
三, izimo zokugcina eziphephile ze-gadinium oxide
IGadinium Oxide iqinile emazingeni okushisa asekamelweni, kepha izimo zokugcina ezilandelayo kufanele ziphawulwe ukuqinisekisa ukuphepha nokusebenza okubonakalayo:
1.I-Ooisture-proof:
IGadinium Oxide ine-hygroscopicity ethile futhi kufanele igcinwe endaweni eyomile ukugwema ukuxhumana nomswakama.
Kunconywa ukusebenzisa isitsha esivaliwe bese wengeza i-desiccant (njenge-silica gel).
I-2.Ight-proof:
IGadinium Oxide iyazwela ukukhanya, nokuvezwa kwesikhathi eside ukukhanya kukhanya kungathinta ukusebenza kwayo.
Kufanele igcinwe endaweni epholile, emnyama.
I-3.Temperature Control:
Izinga lokushisa lesitoreji kufanele lilawulwe ngaphakathi kwebanga lokushisa kwekamelo (15-25 ° C), ukugwema izindawo zokushisa eziphakeme noma eziphansi.
Izinga lokushisa eliphakeme lingadala izinguquko ezihlelekile eGadinium oxide, futhi izinga lokushisa eliphansi lingadala ukunxenxa.
Ukuxhumana kwe-4.Avoid nge-acid:
IGadinium Oxide iyi-alkaline oxide futhi izosabela ngobudlova nge-acid.
Gwema kude nezinto ezi-acidic ngesikhathi sokugcina.
Uthuli Oluphelele:
IGadinium Oxide Powder ingacasula ipheshana lokuphefumula nesikhumba.
Sebenzisa iziqukathi ezivaliwe lapho ugcina futhi ugqoke imishini yokuvikela (efana namaski namagilavu) lapho uphatha.
IV. Izinyathelo zokuzivikela
1.Thiko:IGadinium oxide ngokwayo iphansi ngobuthi, kepha uthuli lwalo lungase lucasule ipheshana lokuphefumula nesikhumba, ngakho-ke ukuxhumana okuqondile kufanele kugwenywe.
Ukulahlwa kwe-2.Waku:Imfucumfucu I-Oxide ye-Meachin kufanele isetshenziswe kabusha noma iphathwe ngokuya ngemithetho yokuphatha amakhemikhali enobungozi ukugwema ukungcoliswa kwemvelo.
Ngokuphathelene nokukhishwa okungenhla, izindlela zokulungiselela kanye nezindlela zokugcina, i-Gadolimium Oxide ephezulu ingatholwa kahle nangokuphephile ukuze ihlangabezane nezidingo zayo emikhakheni yezintokazi, amadivayisi wezokwelapha, njll.
