Waa maxay Lanthanum Carbonate iyo waa codsi, midab?

Lanthanum carbonate(lantanum carbonate), qaacidada molecular ee La2 (CO3) 8H2O, guud ahaan waxa ku jira xaddi go'an oo unugyo biyo ah. Waa nidaamka crystal rhombohedral, waxa ay la falgali kartaa asiidhyada intooda badan, milmi 2.38×10-7mol/L ee biyaha at 25°C. Waxa lagu qurxin karaa kulayl ahaan lanthanum trioxide at 900°C. Inta lagu jiro habka kala-goynta kulaylka, waxay soo saari kartaa alkali. Inta lagu jiro habka kala-goynta kulaylka waxay soo saari kartaa alkali.Lanthanum carbonatewaxaa lagu abuuri karaa carbonates biraha alkali si ay u sameeyaan milix adag kaarboonayt biyo-milmi kara.Lanthanum carbonateDa'da ayaa la soo saari karaa iyadoo lagu darayo karbohaydrayt ammonium oo xad-dhaaf ah oo lagu daro milixda lanthanum ee milmay.

Adeegsada:.Lanthanum carbonatewaa iskudhis aan noolayn oo ka kooban curiyaha lanthanum iyo ion karbonatena. Waxaa lagu gartaa xasillooni xooggan, milmayn hooseeya iyo sifooyinka kiimikada firfircoon. Warshadaha, lanthanum carbonate waxaa si weyn loogu isticmaali karaa dhoobada, elektiroonigga, daawada iyo meelaha kale. Waxaa ka mid ah, carbonate lanthanum ayaa door muhiim ah ka ciyaara warshadaha dhoobada, waxaa loo isticmaali karaa sida midabka, glaze, wax lagu daro galaaska, iwm.; dhinaca qalabka elektarooniga ah, carbonate lanthanum waxaa lagu diyaarin karaa koronto koronto oo sarreeya, heerkulka hooseeya ee qalabka xoogga leh, oo ku habboon wax soo saarka tamarta-cufnaanta sare, oo loo isticmaalo soo saarista kicinta ternary, wax lagu daro carbide cemented; dhanka daawooyinka,lanthanum carbonatewaa wax caadi ah oo lagu daro daawooyinka, waxaana loo isticmaali karaa in lagu daweeyo goobta daawada,lanthanum carbonatewaa daroogo caadi ah oo lagu daro, taas oo loo isticmaali karo daaweynta hypercalcemia, hemolytic uremic syndrome iyo cuduro kale, waxayna ku habboon tahay daaweynta hyperphosphatemia ee bukaannada cudurrada kelyaha ee marxaladda ugu dambeeya. Eray ahaan,lanthanum carbonatewaxay leedahay hawlo badan waxaana si weyn loogu isticmaalaa warshadaha kiimikada casriga ah, cilmiga maadiga, daawada iyo qaybaha kale.

Sida loo soo saaro:

Lanthanum carbonatewaa xarunta ugu weyn ee soo saarista lanthanum oxide [1-4]. Iyada oo xaaladda degdega ah ee sii kordheysa ee ilaalinta deegaanka, ammonium bicarbonate, oo ah soo-dejiye dhaqameed oo loogu talagalay diyaarinta lanthanum carbonate, ayaa inta badan loo adeegsaday wax-soo-saarka warshadaha [5-7], in kasta oo ay leedahay faa'iidooyinka qiimaha hoose ee wax soo saarka iyo waxyaabaha wasakhaysan oo hooseeya. ee karboonayt la helay. Si kastaba ha ahaatee, sababtoo ah eutrophication ee NH + 4 ee biyaha wasakhda ah ee warshadaha, taas oo saameyn weyn ku leh deegaanka, qadarka milixda ammonium ee loo isticmaalo warshadaha ayaa la soo bandhigay shuruudo adag. Sida mid ka mid ah kuwa ugu muhiimsan, sodium carbonate, marka la barbardhigo ammonium bicarbonate, diyaarintalanthanum carbonate in habka biyaha wasakhda ah ee warshadaha oo aan lahayn ammonia, nijaasta nitrogen, si sahlan wax looga qabto; marka la barbardhigo sodium bicarbonate, la qabsiga deegaanka waa mid xoogan [8 ~ 11].Lanthanum carbonateoo leh sodium carbonate sida daadiyaha loogu talagalay diyaarinta carbonate-sodium-yar ee naadirka ah ee carrada waa dhif in lagu soo warramo suugaanta, kaas oo qaata qiimo jaban, hawlgalka fudud ee habka quudinta wanaagsan, iyo sodium-hooseeya.lanthanum carbonatewaxaa lagu diyaariyaa iyadoo la xakameynayo xaaladaha falcelinta ee taxanaha ah.

Taxadirka gaadiidka eelanthanum carbonateBaabuurta gaadiidka waa in lagu qalabeeyaa noocyada iyo tirada ku habboon ee qalabka dab-damiska iyo qalabka daaweynta degdegga ah ee daadsan. Waxaa si adag loo mamnuucay in lagu qaso oo lagu raro oksaydhiyeyaasha iyo kiimikooyinka la cuni karo. Dhuumaha qiiqa ee baabuurka xamuulku wuxuu u baahan yahay in lagu rakibo dab-demiska. Marka baabuurta booyadaha loo isticmaalo gaadiidka, waa in lagu rakibaa silsilado dhulka ah. Si loo yareeyo korantada joogtada ah ee ka dhalata gariirku, waxaa suurtagal ah in lagu rakibo qaybiyayaal dalool oo taangiga ah. Waa mamnuuc in la raro ama la dejiyo qalabka farsamada iyo qalabka u nugul dhinbiilyada. Subaxdii iyo fiidkii xagaaga gaadiidku waa wanaagsan yahay, habka gaadiidka, si looga hortago qorraxda iyo roobka iyo heerkulka sare. Ka fogow isha dabka, meesha kulaylka iyo heerkulka sare inta lagu jiro joogsiga. Gaadiidka waddooyinka waa in loo maraa si waafaqsan dariiqyada loo qoondeeyay, mana aha in lagu istaago meelaha la deggan yahay iyo meelaha dadku ku badan yahay. Gaadiidka tareenada waa ka mamnuuc in ay ku boodaan. Gaadiidka badan ee maraakiibta alwaax ama sibidhka waa mamnuuc. Calaamadaha iyo ogeysiisyada khatarta ah waa in lagu dhejiyaa habka gaadiidka iyadoo la raacayo shuruudaha gaadiidka.
