Teb: Hauv electrolytic refining cov hlau tsis huv yog ua raws li anodethiab cov hlau ntshiab yog ua cathode.

YPuas electrolysis siv hauv kev ua kom cov hlau tsis huv?

txheej txheem ntawm electrolytic refining yog siv los ntxuav cov hlau tsis huv. Hauv cov txheej txheem no, cov hlau tsis huv yog ua anode thiab nyias nyias ntawm cov hlau ntshiab yog ua cathode. Ib qho kev daws ntawm ntsev ntawm cov hlau, uas yuav tsum tau ua kom zoo yog siv los ua ib qho electrolyte.

Cov hlau twg yog siv rau hauv electrolytic refining?

Electrolytic refining yog txheej txheem ntawm refining hlau (tsuas yog tooj liab) los ntawm cov txheej txheem ntawm electrolysis. Raws li cov txheej txheem ntawm cov txheej txheem muaj kev txhawj xeeb, thaum lub sij hawm electrolysis, ib tug loj chunks los yog slab ntawm impure hlau yog siv raws li lub anode nrog ib tug nyias strip ntawm ntshiab hlau ntawm lub cathode.

Dab tsi yog kev ua kom zoo ntawm cov hlau tsis huv?

Nyob hauv metallurgy, refining muaj ntawm purifying ib impure hlau. Nws yog qhov yuav tsum tau paub qhov txawv ntawm lwm cov txheej txheem xws li smelting thiab calcining nyob rau hauv uas ob qhov no koom nrog cov tshuaj hloov pauv rau cov khoom siv raw, whereas hauv refining, cov khoom kawg feem ntau yog zoo tib yam tshuaj rau tus thawj, tsuas yog nws purer.

Vim li cas hauv electrolytic refining impure hlau yog ib txwm muab ua anode?

Tus pas nrig ntawm cov hlau tsis huv yog siv los ua anode thiab nyias daim ntawv ntawm cov hlau ntshiab li cathode. Thaum electrolysis, hlau los ntawm anodeyaj nyob rau hauv cov tshuaj thaum tib tus nqi ntawm cov ntshiab hlau deposits ntawm cathode. Cov impurities zoo li ntau reactive hlau yaj nyob rau hauv cov tshuaj. Tsawg reactive hlau yog insoluble.
