Qhov txawv ntawm electrolytic txo thiab refining yog txoj kev txo electrolytic siv graphite electrodes ntawm tib qhov loj, whereas electrolytic refining txoj kev siv impure hlau li anode thiab ib tug cathode ua los ntawm tib hlau nrog siab purity.
Electrolytic txo thiab ua kom zoo dua yog ob txoj hauv kev lag luam tseem ceeb uas peb tuaj yeem siv los ntxuav cov hlau. Hauv kev txo cov electrolytic, peb tuaj yeem txo cov hlau mus rau hauv lub xeev qis oxidation, uas ua kom yooj yim rho tawm. Nyob rau hauv txoj kev electrolytic refining, cov hlau los ntawm impure anode yuav tso rau ntawm cathode, cia peb rho cov hlau los ntawm cathode.
Kev txo qis hluav taws xob yog dab tsi?
Kev txo cov electrolytic yog txheej txheem ntawm kev txo cov hlau los ntawm electrolysis. Hauv cov txheej txheem no, peb siv ob lub graphite electrodes ntawm tib qhov loj li anode thiab cathode. Cov txheej txheem cuam tshuam nrog txo cov oxides, hydroxides thiab chlorides ntawm cov hlau (uas yog nyob rau hauv lub xeev fused) hluav taws xob. Ntawm no, peb tuaj yeem rho tawm cov hlau no ntawm lub cathode. Cov piv txwv rau cov hlau peb tuaj yeem tau txais los ntawm txoj kev no suav nrog sodium, magnesium, calcium thiab txhuas. Hauv txoj kev no, peb tuaj yeem tau txais cov hlau uas muaj purity siab. Txawm li cas los xij, peb tsis tuaj yeem rho tawm cov hlau uas tsis tshua muaj kev cuam tshuam nrog cov txheej txheem no. Nws yog vim lawv tsim cov oxides tsis tshua muaj zog.

Feem ntau, cov txheej txheem rho tawm feem ntau tsis ua haujlwm ntawm cov hlau uas nyob rau sab saum toj ntawm cov haujlwm ua haujlwm. Txoj kev zoo tshaj plaws rau lawv cov extraction yog txo cov electrolytic vim tias lawv muaj cov electropositive heev, thiab peb tsis tuaj yeem siv cov pa roj carbon monoxide los txo lawv.
Electrolytic Refining yog dab tsi?
Electrolytic refining yog txheej txheem ntawm kev rho tawm cov hlau (hlau peb tuaj yeem tau txais los ntawm txhua txoj kev ua kom zoo) siv electrolysis. Nyob rau hauv txoj kev no, lub anode yog ib qho impure hlau thaiv los ntawm qhov uas peb yuav rho tawm cov hlau thaum lub cathode yog ib qho thaiv ntawm tib hlau nrog siab purity. Tsis tas li ntawd, cov tshuaj electrolytic yog cov tshuaj aqueous ntawm ntsev ntawm cov hlau tshwj xeeb (cov hlau peb yuav rho tawm). Tom qab ntawd, peb tuaj yeem dhau qhov hluav taws xob tam sim no los ntawm lub xov tooj ntawm tes electrolytic. Nws yuav ua rau cov hlau tawg ntawm lub anode thiab nws thiaj li tso rau ntawm cathode. Yog li ntawd, peb tuaj yeem sau cov hlau ntshiab los ntawm cathode. Piv txwv xws li kub refining, nyiaj refining, tooj liab refining, thiab lwm yam.
Qhov txawv ntawm Electrolytic Reduction thiab Refining yog dab tsi?
Kev txo cov electrolytic yog cov txheej txheem ntawm kev txo cov hlau los ntawm electrolysis, thaum electrolytic refining yog txheej txheem ntawm extraction ntawm hlau siv electrolysis. Qhov tseem ceeb sib txawv ntawm electrolytic txo thiab refining yog tias electrolytic txo txoj kev siv graphite electrodes ntawm tib qhov loj, whereas electrolytic refining txoj kev siv ib tug impure metal li anode thiab ib tug cathode ua los ntawm tib hlau nrog siab purity.
Ntxiv mus, electrolytic txo txo cov oxides, hydroxide, thiab chlorides ntawm hlau hluav taws xob, thiab peb tuaj yeem tau txais cov hlau ntshiab thaum kawg ntawm kev rho tawm. Txawm li cas los xij, hauv electrolytic refining, thaum siv hluav taws xob tam sim no, cov hlau tsis huv hauv cov anode dissolves hauv cov tshuaj electrolytic thiab tso rau ntawm cathode.
Hauv qab infographic qhia ntau ntxiv txog qhov sib txawv ntawm electrolytic txo thiab refining.
Summary – Electrolytic Reduction vs Refining
Kev txo cov electrolytic yog cov txheej txheem ntawm kev txo cov hlau los ntawm electrolysis, thaum electrolytic refining yog txheej txheem ntawm extraction ntawm hlau siv electrolysis. Qhov sib txawv tseem ceeb ntawm electrolytic txo thiab refining yog tias electrolytic txo txoj kev siv graphite electrodes ntawm tib qhov loj whereas electrolytic refining txoj kev siv cov hlau tsis huv li anode thiab ib cathode ua los ntawm tib hlau nrog siab purity.
