Awọn akojọpọ ti lanthanum kaboneti
Lanthanum kabonetijẹ ẹya pataki kemikali nkan na kq tilanthanum, erogba, ati awọn eroja atẹgun. Agbekalẹ kemikali rẹ jẹ La2 (CO3) 3, nibiti La ṣe aṣoju ẹya lanthanum ati CO3 duro fun ion carbonate.Lanthanum kabonetijẹ kirisita funfun ti o lagbara pẹlu igbona ti o dara ati iduroṣinṣin kemikali.
Awọn ọna pupọ lo wa fun murasilẹ lanthanum carbonate.Ọna ti o wọpọ ni lati fesiirin lanthanumpẹlu dilute nitric acid lati gba lanthanum iyọ, eyi ti o ti wa ni lenu pẹlu soda kaboneti lati dagbalanthanum kabonetiojoro. Ni afikun,lanthanum kabonetitun le gba nipa didaṣe iṣuu soda kaboneti pẹlu kiloraidi lanthanum.
Kaboneti Lanthanum ni ọpọlọpọ awọn ohun elo pataki.Ni akọkọ,lanthanum kabonetile ṣee lo bi ohun elo aise pataki fun awọn irin lanthanide.Lanthanumni atoje aiye irinpẹlu oofa pataki, opiti, ati awọn ohun-ini elekitirokemika, ti a lo lọpọlọpọ ni awọn aaye bii itanna, optoelectronics, catalysis, ati irin.Lanthanum kaboneti, gẹgẹbi iṣaju pataki ti awọn irin lanthanide, le pese ohun elo ipilẹ fun awọn ohun elo ni awọn aaye wọnyi.
Lanthanum kabonetitun le ṣee lo lati ṣeto awọn agbo ogun miiran. Fun apẹẹrẹ, fesilanthanum kabonetipẹlu imi-ọjọ sulfuric lati ṣe agbejade imi-ọjọ lanthanum le ṣee lo lati ṣeto awọn ayase, awọn ohun elo batiri, bbl Idahun tilanthanum kabonetipẹlu ammonium iyọ fun wa ammonium iyọ tilanthanum, eyi ti o le ṣee lo lati ṣeto awọn oxides irin lanthanide,ohun elo afẹfẹ lanthanum, ati be be lo.
Lanthanum kabonetitun ni iye ohun elo oogun kan. Iwadi ti fihan pelanthanum kabonetiO le ṣee lo lati ṣe itọju hyperphosphatemia. Hyperphosphatemia jẹ arun kidirin ti o wọpọ, nigbagbogbo pẹlu ilosoke ninu awọn ipele irawọ owurọ ninu ẹjẹ.Lanthanum kabonetile darapọ pẹlu irawọ owurọ ninu ounjẹ lati dagba awọn nkan insoluble, nitorinaa dinku gbigba ti irawọ owurọ ati ifọkansi ti irawọ owurọ ninu ẹjẹ, ṣiṣe ipa itọju ailera.
Lanthanum kabonetitun le ṣee lo lati ṣeto awọn ohun elo seramiki. Nitori iwọn otutu ti o dara julọ ati iduroṣinṣin kemikali,lanthanum kabonetile mu awọn agbara, líle, ati wọ resistance ti seramiki ohun elo. Nitorinaa, ni ile-iṣẹ seramiki,lanthanum kabonetini igbagbogbo lo lati ṣeto awọn ohun elo bii awọn ohun elo otutu ti o ga, awọn ohun elo itanna, awọn ohun elo opiti, ati bẹbẹ lọ.
Lanthanum kabonetitun le ṣee lo fun aabo ayika. Nitori agbara adsorption rẹ ati iṣẹ ṣiṣe katalitiki,lanthanum kabonetile ṣee lo ni awọn imọ-ẹrọ itọju ayika gẹgẹbi itọju omi idọti ati isọdi gaasi eefin. Fun apẹẹrẹ, nipa fesilanthanum kabonetipẹlu eru irin ions ni omi idọti lati dagba insoluble precipitates, awọn ìlépa ti yiyọ eru awọn irin ti wa ni waye.
Lanthanum kabonetijẹ nkan kemikali pataki kan pẹlu iye ohun elo lọpọlọpọ. Kii ṣe ohun elo aise pataki nikan fun awọn irin lanthanide, ṣugbọn tun le ṣee lo ni igbaradi ti awọn agbo ogun miiran, itọju hyperphosphatemia, igbaradi awọn ohun elo seramiki, ati aabo ayika. Pẹlu ilọsiwaju ilọsiwaju ti imọ-jinlẹ ati imọ-ẹrọ, awọn ireti ohun elo tilanthanum kabonetiyoo tun gbooro sii.
