Izinqubo Zokuhlanza Ukuhlanza Okuphezulu

Ukuhlanjululwa kwe-Selenium ePhezulu (≥99.999%) kubandakanya inhlanganisela yezindlela zomzimba nezamakhemikhali ukususa ukungcola okunjengeTe, PB, FE, kanye. Okulandelayo izinqubo ezibalulekile namapharamitha:

1. I-vacuum distillation

Inqubo yokugeleza:

1. Beka i-stenium ye-crude (≥99.9%) kwi-quartz ebekiwe ngaphakathi kwesithando se-vacuum distillation.

2. Ukushisa kuya ku-300-500 ° C ngaphansi kwe-vacuum (1-100 PA) imizuzu engama-60-180.

3

4. Qoqa i-selenium kusuka ku-condenser ephezulu;

Amapharamitha:

- Ukushisa: 300-500 ° C

- Ingcindezi: 1-100 Pa

- Izinto ze-condenser: i-quartz noma insimbi engenacala.

2. Ukuhlanza amakhemikhali + ukugcwala kwe-vacuum

Inqubo yokugeleza:

1..

2. I-solvent extruction: Dissolve e-SEO₂ ngesisombululo se-ethanol-water, hlunga uTeo₂ uqonde.

3. Ukuncishiswa: Sebenzisa i-Hydrazine (N₂H₄) ukunciphisa i-SEO₂ ku-Selenium Elemently Selenium.

I-4. Deep de-te: oxidize Selenium futhi ku-SEO₄²⁻, bese ukhipha i-TE usebenzisa isizinda solvent.

I-5

Amapharamitha:

- Ukushisa kwe-oxidation: 500 ° C

- I-Hydrazine DOSAGE: okweqile ukuze uqinisekise ukuncishiswa okuphelele.

3. Ukuhlanzwa kwe-electrolytic

Inqubo yokugeleza:

1. Sebenzisa i-electrolyte (isib., I-selenous acid) ene-density yamanje ye-5-10 A / DM².

2. I-Selenium Deposits e-Coutrium, ngenkathi selenium oxides lelanisa i-anode.

Amapharamitha:

- Ubuningi Bamanje: 5-10 A / DM²

- I-electrolyte: Isixazululo se-selenous acid noma i-selenate.

4. Ukukhishwa kwe-solvent

Inqubo yokugeleza:

1. Khipha i-SE⁴⁺ kusuka kusisombululo usebenzisa i-TBP (Tributyl phosphate) noma i-TOA (Trioctylamine) ku-Hydrochloric noma i-Sulfuric Acid Media.

2

Amapharamitha:

- I-Extract: TBP (HCL Medium) noma i-TOA (H₂SO₄ Medium)

- Inani lezigaba: 2-3.

5. I-Zone Becting

Inqubo yokugeleza:

1. Ephindaphindekayo-Melt Selenium Ingots ukususa ukungcola ukungcola.

2. Ilungele ukufeza> Ubumsulwa be-5N kusuka ezintweni zokuhlanza eziphezulu.

QAPHELA: Dinga imishini ekhethekile futhi inamandla amakhulu.

Ukuthola isiphakamiso

Ukuze uthole inkomba ebonakalayo, bhekisa kulezi zibalo ezilandelayo ezincwadini:

- Ukusethwa kwe-rusuum distillation: schematic sohlelo lwe-condenser esiteji ezimbili.

- Umdwebo wesigaba se-SE-TE: ukhombisa izinselelo zokwehlukanisa ngenxa yamaphoyinti asolisekile asondele.

Ukunqubekela phambili

- I-Vacuum distillation kanye nezindlela zamakhemikhali:

- I-electrolytic ne-solvent ukukhishwa:

- Amasu Athuthukile nezinselelo:
