Ukulungiselela i-barium
Ukulungiswa kwezimboni kweI-Metallic BariumKubandakanya izinyathelo ezimbili: Ukulungiselela i-barium oxide kanye nokulungiswa kwensimbi ye-barium ngokuncishiswa kwensimbi (ukuncishiswa kwe-aluminimic).

(1) Ukulungiselela i-barium oxide
I-Barite Ore yekhwalithi ephezulu kumele iqale ikhethwe ngesandla futhi ixhumeke, bese i-iron kanye ne-silicon zisuswa ukuthola ukugxila okuqukethe okuqukethe ama-barium sulfate angaphezu kuka-96%. I-Ore powder enesayizi eyizinhlayiyana engaphansi kwama-mesh angaphansi kwama-20 ixutshwe namalahle noma kaphethiloli I-barium sulfate incishiswa yaba yi-barium sulfide (eyaziwa kakhulu ngokuthi "umlotha omnyama"), kanye ne-barium sulfide solution kufakwa emanzini ashisayo. Ukuze uguqule i-barium sulfide ibe yi-barium carbonate yezulu, i-sodium carbonate noma i-carbon dioxide idinga ukungezwa kusisombululo samanzi se-barium sulfide aqulfide aquali. I-Barium Oxide ingatholakala ngokuxuba i-barium carbonate nge-carbon powder futhi uyikhanyise ngenhla kwama-800 ℃. Kufanele kuqashelwe ukuthi i-barium oxide i-oxidised ukwenza i-barium peroxide ngo-500-700 ℃, futhi i-barium peroxide ingaboshelwa ukwakha i-barium oxide ngo-700-800 ℃. Ngakho-ke, ukuze ugweme ukukhiqizwa kwe-barium peroxide, umkhiqizo oqokiwe udinga ukuphonswa noma ukucishwa ngaphansi kokuvikelwa kwegesi ye-inert.
(2) Indlela yokunciphisa i-aluminic ukukhiqiza i-barium yensimbi
Ngenxa yezithako ezahlukene, kunokusabela okubili kwe-aluminium enciphisa i-barium oxide:
6Bao + 2Al → 3bao • Al2o3 + 3ba ↑
Noma: 4bao + 2al → Bao • Al2o3 + 3ba ↑
Ku-1000-1200 ℃, lokhu kusabela okubili kuveza i-barium encane kakhulu, ngakho-ke ipompo ye-vacuum iyadingeka ukuqhubeka ngokudlulisela i-barium vapor kusuka endaweni yokuphendula kuya endaweni yokuvuselela ukuze ukusabela kungaqhubeka ngakwesokunene. Izinsalela ngemuva kokuphendula zinobuthi futhi zidinga ukuphathwa ngaphambi kokuthi ilahlwe.
Ukulungiselela izinhlanganisela ze-barium ezijwayelekile
(1) Indlela yokulungiselela iBarium Carbonate
① indlela ye-carbonization
Indlela ye-carbonization ikakhulukazi ifaka ukuxuba i-barite ne-coal ngesilinganiso esithile, ibachoboza kwi-kiln ejikelezayo nokukhangisa bese ibanciphisa ngo-1100-1200 ℃ ukuthola i-barium sulfide ehlekisayo. I-Carbon Dioxide yethulwa kwikhambi le-barium sulfide ye-carbonization, futhi ukusabela kungokulandelayo:
Bas + CO2 + H2O = Baco3 + H2S
I-barium carbonate slurry ye-barium iseduzane, igezwe futhi i-vacuum ihlungiwe, bese yomiswa futhi yachobozwa ngo-300 ℃ ukuthola umkhiqizo we-barium carbonate ophelile. Le ndlela ilula inqubo futhi iphansi ngezindleko, ngakho-ke yamukelwa iningi labakhiqizi.
② indlela yokubola kabili
I-Barium sulfide ne-ammonium carbonate eqhubeka nokuvundwa kabusha, futhi ukusabela kungokulandelayo:
I-Bas + (NH4) 2CO3 = BACO3 + (NH4) 2S
Noma i-barium chloride iphendula nge-potassium carbonassite, futhi ukusabela kungokulandelayo:
Bacl2 + K2Co3 = Baco3 + 2kcl
Umkhiqizo otholwe ekuphenduleni ugezwe, ungcolile, omisiwe, njll ukuze uthole umkhiqizo we-barium Carbonate oqediwe.
Indlela ye-barium carbonate indlela
I-Barium Carbonate Powder yaphendulwa ngosawoti we-ammonium ukukhiqiza usawoti we-barium we-soluble, kanye ne-ammonium carbonate iyavuselelwa. Usawoti we-soluble we-barium ungezwe ku-ammonium carbonate ukucacisa i-barium Carbonate Carbonate ecwebile, ehlungiwe futhi omiswe ukwenza umkhiqizo ophelile. Ngaphezu kwalokho, utshwala bomama butholakele bungaphinde busetshenziswe kabusha. Ukuphendula kungokulandelayo:
Baco3 + 2hcl = Bacl2 + H2O + CO2
Bacl2 + 2nH4OH = BA (oh) 2 + 2nh4cl
I-BA (OH) 2 + CO2 = Baco3 + H2O
(2) Indlela yokulungiselela ye-barium titanate
① indlela esesigabeni esiqinile
I-Barium Titanate ingatholwa nge-carbonate carbonate ye-carbonate ne-titanium dioxide, futhi noma yiziphi ezinye izinto zokwakha zingadonswa kuyo. Ukuphendula kungokulandelayo:
I-Tio2 + Baco3 = IBatio3 + CO2 ↑
② indlela ye-cops
IBarium Chloride neTitanium Tetrachloride zixubene futhi zichithwe ngamanani alinganayo, zifudunyezwa ku-70 ° C, bese kuthi i-oxalic acid ingezwe i-hydrate tuimitanyl oxamate [i-batio (c2o4) 2 • bese i-prolyzed ukuthola ukuthola i-barium Titanate. Ukuphendula kungokulandelayo:
Bacl2 + Ticl4 + 2h2C2o4 + 5h2O = Batio (C2O4) 2 • 4h2O ↓ + 6hcl
IBatio (C2O4) 2 • I-4H2O = IBatio3 + 2CO2 ↑ + 2co ↑ + 4h2o
Ngemuva kokushaya i-metatitanic acid, kufakwa isixazululo se-barium chloride, bese kufakwa i-ammonium carbonate ngaphansi kokuvusa ukukhiqiza i-coutium carbonate ne-metatitanic acid, etholwa ukuthola umkhiqizo. Ukuphendula kungokulandelayo:
Bacl2 + (NH4) 2CO3 = BACO3 + 2nH4CL
H2Tio3 + Baco3 = I-Batio3 + CO2 ↑ + H2O
(3) Ukulungiselela i-barium chloride
Inqubo yokukhiqiza yeBarium Chloride ikakhulukazi ifaka phakathi indlela ye-hydrochloric acid, indlela ye-barium carbonate, indlela ye-calcium chloride kanye nendlela ye-magnesium chloride ngokuya ngezindlela ezahlukahlukene noma izinto eziluhlaza.
① Indlela ye-Hydrochloric acid. Lapho i-barium sulfide iphathwa nge-hydrochloric acid, ukusabela okuyinhloko yile:
Bas + 2hci = Bacl2 + H2S ↑ + q
Indlela ye-carbonate ye-carbonate. Kwenziwe ngeBarium Carbonate (Barium Carbonate) njengento eluhlaza, ukuphendula okuyinhloko yile:
Baco3 + 2hci = Bacl2 + CO2 ↑ + H2O
Indlela ye-③Carbonization
Imiphumela ye-barium empilweni yabantu
Ngabe i-barium iluthinta kanjani impilo?
I-Barium akuyona into ebalulekile emzimbeni womuntu, kepha inomthelela omkhulu empilweni yabantu. I-Barium ingavezwa ku-barium ngesikhathi se-barium mining, ukunqwabelana, ukukhiqiza, kanye nokusebenzisa amakhompiyutha e-barium. I-Barium namakhompiyutha ayo angangena emzimbeni ngepheshana lokuphefumula, ipheshana lokugaya ukudla, nesikhumba esilimele. Ubuthi be-barium emsebenzini budalwa ikakhulukazi ukuphefumula inhalation, okwenzeka ezingozini ngesikhathi sokukhiqiza nokusebenzisa; Ubuthi be-barium abangasebenzi kahle bubangelwa ikakhulukazi ngokuthathina kokugaya ukumunca, okubangelwa kakhulu ukufakwa ngengozi; Amakhompiyutha we-barium we-liquid soluble angangenwa ngesikhumba esilimele. Ubuthi be-barium obukhulu bubangelwa kakhulu ukungenisa ngengozi.
Ukusetshenziswa Kwezokwelapha
(1) I-Barium Meat Adiography
I-Barium Meat radiography, eyaziwa nangokuthi i-Digetive Tract Barium Radiography, yindlela yokuhlola esebenzisa i-barium sulfate njenge-ejenti ehlukile ukukhombisa ukuthi ngabe kukhona izilonda zokugaya emanzini ngaphansi kwe-x-ray irradiation. I-Barium Meat radiography yokufakwa ngomlomo kwama-ejenti wokungafani, kanye ne-sodium barium sulfate esetshenziswe njenge-ejenti yokungafani ku-infoluble emanzini kanye nama-lipids futhi ngeke kungeniswe yi-mucosa esiswini, ngakho-ke akunakuhlukumezeka kubantu.
Ngokwezidingo zokuxilongwa kwezempilo kanye nokwelashwa, i-gastrointestinal barium yokudla okuhlangenwe nakho kokudla okuphezulu kwe-barium, isidlo esifuywini sase-gastrointestinal, i-clolon barium enema kanye nokuhlolwa kwamathumbu amathumbu we-barium nenema kanye nokuhlolwa kwamathumbu amathumbu kanye nokuhlolwa kwamathumbu amathumbu kanye nokuhlolwa kwamathumbu amathumbu kanye nokuhlolwa kwamathumbu amathumbu kanye nokuhlolwa kwamathumbu amathumbu we-barium enema.
Ubuthi be-barium
Imizila yokuvezwa
I-Barium ingadalulwaitheyiliNgesikhathi se-barium mining, ukunqwabelana nokukhiqiza. Ngaphezu kwalokho, i-barium kanye nezinhlanganisela zayo zisetshenziswa kabanzi. Usawoti we-barium ojwayelekile ufaka i-barium carbonate, i-barium chloride, i-barium sulfide, i-barium nitrate, ne-barium oxide. Ezinye izidingo zansuku zonke ziqukethe i-barium, efana ne-barium sulfide emithini yokususwa kwezinwele. Abanye abaphathi bezinambi zokulawula izinambuzane noma ama-rodenticicides baqukethe usawoti we-barium oncibilikayo njenge-barium chloride ne-barium carbonate.
