Teb: Hauv electrolytic refining cov hlau tsis huv yog ua raws li anodethiab cov hlau ntshiab yog ua cathode.
Yog tsim thaum lub sij hawm electrorefining?
Nyob rau hauv cov kauj ruam electrorefining, impurities zoo li Fe, Ni, Zn tau yaj nyob rau hauv cov tshuaj thaum Au, Ag thiab Pt deposited li anode av nkos hauv qab anode.
Cov hlau twg tau ua kom zoo los ntawm electrorefining?
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.
Vim li cas cov hlau tsis huv yog ua anode hauv electro refining txheej txheem piav qhia?
Tab sis raws li peb twb tau tham lawm, cov hlau tsis huv yog ua anode thiab cov hlau ntshiab yog siv los ua cathode. Yog vim li cas - Cov hlau ntshiab tau tso rau ntawm anode av nkos. Tab sis cov hlau ntshiab tau tso rau ntawm cathode thiab impurities tsim anode av nkos.
Yuav ua li cas thaum lub sij hawm electrorefining ntawm impure tooj liab?
Electrorefining entails electrochemically dissolving tooj liab los ntawm impure tooj liab anodes rau hauv electrolyte uas muaj CuSO4 thiab H2SO 4 thiab tom qab ntawd electrochemically tso cov tooj liab ntshiab ntawm cov electrolyte mus rau stainless hlau los yog tooj liab cathodes. … Soluble impurities tawm hauv lub cell nyob rau hauv tsis tu ncua ntws electrolyte.
