Mekhoa e phahameng ea pountium ea bohloeki

Ho hloekisoa ha Selenium ea bohloeki bo phahameng (≥999%) e kenyelletsa ho kopanya mekhoa ea 'mele le ea lik'hemik'hale ho tlosa litšila tse kang Te, PB, fes. Tse latelang ke lits'ebetso tsa bohlokoa le liparamente:

1. Sekhechana sa vacuum

Phetoho ea phallo:

1. Sebaka se sephara senium (≥99.9%) ka qubu e sa tloaelehang ka har'a sebopi sa seriti sa vacuum.

2. Mamela ho fihlela 300-500 ° C ka tlung (1-100 pa) bakeng sa metsotso e 60-180.

3. Li-compters tse 3 tsalemium

4. Bokella sekoaelong se kaholimo; 碲 (Te) le liphoso tse ling tse nang le bofubelu bo bolelele bo setseng sethaleng.

Liparamente:

- Mocheso: 300-500 ° C

- khatello: 1-100 pa

- Boitsebiso ba Khoutu: QuaelstZ kapa tšepe e se nang letsoai.

2. Tlhoekiso ea lik'hemik'hale +

Phetoho ea phallo:

1. Moralo oa oxidation: Karabelo ea lineuium e sekhutlo (99.9%) e nang le likhase tse 500 tsa C ho theha likhase tsa Seo₂ le Teo₂.

2. Solvention Exartction: Qhala seo seo se ka se etsang metsi a leoatle, sefako sa Teo se bitsoang Teole

3. Phokotso: Sebelisa hydrazine (n₂h₄) ho fokotsa seo₂ seo ho sona sengolo sa mantlha.

4. Kholo ea DE: Oxidize Selenium hape khoe e ntšetsa pele ho sebelisa solvention ho tsoa.

5. Sentiri sa Xuum sa ho qetela: PRILYIALY NEWNE ATRIMO HO 300-500 ° C le 1-100A ho fihlela 6n (99.999%) PUSELETSO))

Liparamente:

- Mocheso oa oxida: 500 ° C

- DALDDRAZINE DASAGE: E fetela pele ho netefatsa phokotso e felletseng.

3. Ho hloekisoa hoa elektrolytictictic

Phetoho ea phallo:

1. Sebelisa electrolyte (mohlala, selenous acid) e nang le letsoalo la hona joale la 5-10 A / DM.

2. Li-amanatla ka cathode, ha Selenium Oxides a ikhethile ho anode.

Liparamente:

- Tekano ea hajoale: 5-10 a / dm²

- Electrolyte: Sellous Acid kapa Sella.

4. E-ba soeufatsa

Phetoho ea phallo:

1. E ntša karolo ea tharollo e sebelisang tbp (Trifutsl phosphate) kapa toa (Trioctyloric kapa sulfuric mecha ea litaba.

2. Strip le ho bula li-renenium, ebe u pheta-pheta.

Liparamente:

- E mong: Tbp (HCL e mahareng) kapa toa (H₂so₄ Medium)

- Palo ea methati: 2-3.

5. Sebaka se qhibilihang

Phetoho ea phallo:

1. Sebaka se lulang se le teng ka linako tsohle ho tlosa litšila tsa traces.

2. E loketse ho fihlela> 5n bohloeki ho tloha lisebelisoa tse phahameng tsa bohloeki.

Tlhokomeliso: E hloka lisebelisoa tse ikhethang ebile li matla haholo.

Tlhahiso

Bakeng sa litlhaloso tse bonahalang, sheba lipalo tse latelang ho tsoa ho lingoliloeng:

- Sethala sa ho senyeha: Sethala sa ho senyeha: Bokutu ea tsamaiso ea metsero ea metsela e peli.

- Se-Chase Sefeterate: Fana ka liphephetso tsa karohano ka lebaka la lintlha tse phehang haufi.

Litšupiso

- Mekhoa ea ho se sebetse hantle le ho sebelisa lik'hemik'hale:

- E eletshwane le electrolytic le solvent:

- Mekhoa e tsoetseng pele le liphephetso:
