(1) Ho lokisa ha barium oxide
Mokhoa oa boleng bo phahameng o tlameha ho khethoa matsoho ebile o phaphametse, ebe o tlosoa ka tšepe le silingoeng ho fumana ho tsepamisa mohopolo ho feta 96% Barium sulfate. Powder ea Ore e nang le boholo ba karoloana e ka tlase ho 20 mesh e kopantsoeng le phofo ea mashala kapa peteroleum. Baruum sulfate e fokotsehile ho tulfide (e tsejoang ka hore ke "molora o motšo"), 'me tharollo ea Sulfide e tumme ka metsi a chesang. Bakeng sa ho fetola sulfide ea Elium Slumide ho The Bohari Insunya Carbonate kapa Carbon dioxide kapa carbon dioxide Barium oxide e ka fumanoa ka ho kopanya carbonate ka carbonate le phofo ea carbon le ho e bala ho kaholimo ho 800 ℃. Re lokela ho hlokomela hore barum oxide e tlosoe ho ba ba haxide ba haxium peroxide ho ea 500-800 ℃. Ka hona, molemong oa ho qoba tlhahiso ea barium peroxide e hlokang ho foka kapa ho tima ts'ireletso ea khase ea methapo ea kelello.
(2) mokhoa oa ho fokotsa aluminormic ho hlahisa moriri oa tšepe oa tšepe
Ka lebaka la metsoako e fapaneng, ho na le karabelo e 'meli ea aluminium Resouse oxide:
6ba + 2al → 3BAO • Al2O3 + 3B
Kapa: 4bao + 2al → Al2O3 + 3Ba ↑
Ka 1000-1200 ℃, maikutlo ana a mabeli a fana ka barium, kahoo pompo e sa sebetseng hantle e tsoa sebakeng sa karabelo ho ea ho se sebetse hantle ho fihlela ka ho le letona. Masala a kamora hore a arabele a tšoaetsoe 'me a hloka ho phekoloa pele ho ka lahloa.
Ho hlophisoa ha metsoako e tloaelehileng ea bahatuli
(1) Mokhoa oa ho lokisa oa carbonate
Mokhoa oa ho betlication
Mokhoa oa ho khomarela haholo o kenyelletsa ho kopanya metakanye le mashala ka bongata bo itseng, ho ba hanyetsa ebe u ba theola ka 1100-1200 ℃ ho fumana qubu ea metsi. Carbon dioxide e hlahisoa tharollo ea Sulfide ea Sulfide bakeng sa carbonization, 'me karabelo e tjena:
Bas + h2O = baco3 + h2s
Mokhabiso o fumanoeng o fetotsoe o fokotsehile, o hlatsoitsoe le o hlatsoitsoeng le o sithabetseng ebe o sithabetsoa ka li-300 ℃ ho fumana sehlahisoa sa carbonate se halikiloeng. Mokhoa ona o bonolo ts'ebetsong le ka theko e tlase, kahoo o amoheloa ke bahlahisi ba bangata.
Mokhoa o habeli oa ho bolaoa
Barium sulfide le Ammonium carbonate ea Double Decpesition, 'me karabelo e tjena:
Bas + (nh4) 2co3 = baco3 + (NH4) 2s
Kapa barium chloride chlonide ka pokello ea potasiamo, 'me karabelo e tjena:
Bal2 + k2co3 = baco3 + 2kcl
Sehlahisoa se fumanoang se tsoang se tsoang se tsoang se hlatsoitsoe, se omme, se omisitsoeng, joalo-joalo ho fumana sehlahisoa sa carbonate se felileng.
Mokhoa oa ho chesoa ke Carbonate
Pofo ea Moriri Carbonate e arabela le letsoai la Amomonium ho hlahisa letsoai le qhibilihileng, 'me ammonium carbonate e sebelisoa hape. Sello sa Balium se letsoai se eketsoa ho ammonium carbonate ho omisa carbonate e khubelu, e fuoeng le ho otloa ho etsa sehlahisoa se felileng. Ntle le moo, joala ba mme ba fumanoe bo ka sebelisoa hape. Karabelo e tjena:
Baco3 + 2Hl = Bal2 + h2O + co2
Bac2 + 2nh4h = BA (OH) 2 + 2NH4CCL
Ba (oh) 2 + baco3 + h2O
(2) Mokhoa oa ho lokisa oa li-tatatate
Mokhoa o tiileng oa bokha
Baroum Tatanate e ka fumanoa ka ho bala li-callenate carbonate le titanium dioxide, 'me lisebelisoa tse ling li ka kenngoa ka ho kena. Karabelo e tjena:
Tio2 + Baco3 = Batio3 + co
Mokhoa oa ho hlophisa kalafo
Barium chlonide le titanium Tetrachloride ba kopantsoe le ho qhibiliha ho 70 ° ho fihlela 7 • Ebe pyrolyzed ho fumana basium tatanate. Karabelo e tjena:
Bal2 + Cactl4 + 5H2O = Batio (C2O4) 2 • 4H2O ↓ + 6HCCL
Batio (c2o4) 2coo = Batio3 + 2co2 ze 4h2O
Kamora ho otla metatitanic, tharollo ea ba ha e eketsoa, ebe Ammonium carbonate e eketsoa ho hlahisa chelete le metatitanic acid ea ho fumana sehlahisoa. Karabelo e tjena:
Bal2 + (nh4) 2co3 = baco3 + 2nh4cl
H2tio3 + baco3 = Batio3 + co2 ↑ · ↑
(3) Ho itukisetsa ka Barium chloride
Ts'ebetso ea tlhahiso ea Barium chlonide e kenyelletsa mokhoa oa acid ea hydrocloric, mokhoa oa carbonate, mokhoa oa chlonide le lisebelisoa tsa magnesiun.
Mokhoa oa hydrochloric acid. Ha Barium Sulfide e tšoaroa ka hydrocloric acid, karabelo e ka sehloohong ke:
2hci = BACT2 + H2s ↑ Hello
Mokhoa oa ho chechisa Carbonate. E entsoe ka li-carbonate tsa moriri (tse halikiloeng tsa moriri
Baco3 + 2hti = bac2 + ze * ↑ ↑
Mokhoa oa ho fetolela
Liphello tsa Baime Bophelong ba motho
Barosu ba ama bophelo bo botle joang?
Barium ha se ntho ea bohlokoa bakeng sa 'mele oa motho, empa e na le tšusumetso e kholo bophelong ba motho. Barium e ka pepesoa ba bajume nakong ea meepo e feto-fetohang, e thella, e etsa lintho tse ngata le tšebeliso ea litsoso tsa batumo. Barium le likhanyane tsa eona li ka kenya 'mele ka pampitšana ea phefumoloho, pampitšana e mpe le letlalo le senyehileng. Chetion ea mesebetsi ea moriri e bakoang haholo ke ho inhalation ea ho hema, e etsahalang likotsi nakong ea tlhahiso le ts'ebeliso; Che-che, chefo e hahiloeng habonolo e bakoa haholo ke ho ja lijo tse ling tsa lijo, boholo bo bakoang ke ho kenella ka phoso; Metsoako ea merobo e nang le metsi e ka kenelle ka letlalo le likotsi tse lemetseng. Chefo e matla ea turute e bakoa haholo ka ho kenella ka phoso.
Ts'ebeliso ea Bongaka
(1) Lijo tsa mojari oa moriri
Mokhoa oa lijana tsa moriri oa moriri o ratoang haholo o sebelisang mofuta oa turnute e le hore o tla bontša hore na ho na le liso tse sebelisang lipirekeng tse ling tlasa X-ray. Boholo ba li-harae tsa Barium ke karolo ea molomo, 'me ha e le hantle mucosa e se nang chestrointestil, ka hona ha e na ho chefo ho batho.
Ho latela litlhoko tsa tlhahlobo ea bongaka le kalafo, pastrointestina e ka aroloa ka har'a naha ea thepa ea paterointestinas, Colon Barium Enema.
