I-Electrolysis yindlela esebenzisa amandla kagesi ukushayela ukusabela kwamakhemikhali okungazenzeki. Kubandakanya ukuhlukaniswa kwama-molecule ayingxube abe ama-ion noma izakhi zawo kusetshenziswa inqubo ye-oxidation nokunciphisa.Ama-electrode e-graphitezidlala indima ebalulekile ekusizeni i-electrolysis ngokusebenzisa izici zabo ezihlukile, njengokuhamba kahle kukagesi kanye nokuzinza kwamakhemikhali.
Kungani ama-electrode e-graphite esetshenziswa ku-electrolysis?
Amaseli e-Electrolytic aqukethe ama-electrode amabili acwiliswe kusixazululo se-electrolyte. I-electrode exhunywe kutheminali ephozithivu yendawo kagesi ibizwa ngokuthi i-anode, kuyilapho i-electrode exhunywe esikhumulweni esinegethivu ibizwa ngokuthi i-cathode. Lapho amandla kagesi edlula kusixazululo se-electrolyte, ama-cation adlulela ku-cathode, kuyilapho ama-anion eqhubekela ku-anode. Lokhu kunyakaza kuholela ekuphenduleni kwamakhemikhali okufunayo kanye nokwakheka komkhiqizo.
I:Ama-electrode e-graphite ane-conductivity kagesi enhle kakhulu.
Ukusukai-graphite chemical formularsingakwazi ukwazi ukuthi i-graphite iwuhlobo lwekhabhoni olunohlelo oluyingqayizivele lwama-athomu, nama-electron ahlukaniswa phezu kwesakhiwo sonke. Lokhu delocalization kuvumela graphite ukuqhuba ugesi ngempumelelo. Lapho kusetshenziswa ama-electrode e-graphite kuseli ye-electrolytic, amandla kagesi aqhutshwa kalula nge-electrode, okwenza ukunyakaza kwama-ion kanye nokusabela kwamakhemikhali okufunayo kwenzeke.
II:Ama-electrode egraphite anikeza ukuqina kwamakhemikhali.
I-Electrolysis ngokuvamile ihilela ukusabela kwamakhemikhali okunonya okungadala ukugqwala noma ukuwohloka kwama-electrode. Nokho, i-graphite imelana kakhulu nokuhlaselwa kwamakhemikhali. Ayisabeli ngama-electrolyte amaningi, okwenza kube ukukhetha okuthembekile kokusetshenziswa isikhathi eside kumaseli e-electrolytic. Lokhu kuzinza kwamakhemikhali kuqinisekisa ukuthi ama-electrode agcina ukwakheka nokusebenza kwawo isikhathi eside, okuwenza angabizi kakhulu ekusetshenzisweni kwezimboni.
III:Ama-electrode egraphite ahlinzeka ngendawo enkulu yokusabela okufunayo ukuthi kwenzeke.
Ama-electrode asetshenziswa ku-electrolysis ngokuvamile asesimweni samapuleti amakhulu noma izinduku. Isakhiwo se-graphite esinezingqimba sivumela ukuhlangana kwama-ion, sinikeze izindawo zokuxhumana ezengeziwe zokusabela kwamakhemikhali. Le ndawo eyandayo ithuthukisa ukusebenza kahle kwe-electrolysis futhi ivumela amazinga okukhiqiza ngokushesha.
IV:Ama-electrode egraphite anikeza ukumelana okuphansi nokugeleza kukagesi.
Ukumelana neseli ye-electrolytic kungaholela ekulahlekelweni kwamandla ngendlela yokushisa. Kodwa-ke, ukwakheka kwe-graphite nokusebenza kahle kunciphisa lokhu kulahlekelwa, kunciphisa ukusetshenziswa kwamandla okuphelele kwenqubo ye-electrolysis. Lokhu kusebenza kahle kukagesi kubalulekile ekusetshenzisweni kwezimboni ezinkulu lapho izindleko zamandla nomthelela wemvelo kuwukucatshangelwa okubalulekile.
V: Ama-electrode e-graphite anikeza amandla aphelele emishini nokuzinza.
Amaseli e-Electrolytic avame ukusebenza ngaphansi kwamazinga okushisa aphezulu nezingcindezi, ezingafaka ingcindezi enkulu kuma-electrode. Amandla emvelo e-graphite ayivumela ukuthi imelane nalezi zimo ngaphandle kokuwohloka noma ukuwohloka. Ukuzinza kwayo kuqinisekisa ukuthi ukuma nesakhiwo se-electrode kuhlala kungashintshi, kuqinisekisa ukusebenza okungaguquki nokuthembekile.
VI:Isicelo se-graphite electrodeiguquguquka.
Ezinqubweni ezihlukahlukene ze-electrolytic. I-electrode ye-graphite ingasetshenziswa ekukhiqizeni i-chlorine, i-aluminium, ithusi, namanye amakhemikhali nezinsimbi ezihlukahlukene. Ukuguquguquka kwama-electrode e-graphite ngokosayizi, ukuma, nokucushwa kuvumela ukuba bazivumelanise nemiklamo ehlukene ye-electrolytic cell, inikeze ukusetshenziswa kalula nokuhambisana nengqalasizinda ekhona.
VII:Ama-electrode e-graphite ahambisana nemvelo.
Uma kuqhathaniswa nezinye izinto ze-electrode. Ezinye izinto eziningi ze-electrode, njengomthofu noma ezinye izinsimbi, zingaholela emikhiqizweni enobuthi ngesikhathi se-electrolysis. I-graphite, ngakolunye uhlangothi, iyinsiza engenabo ubuthi futhi echichimayo, okwenza kube ukukhetha okuzinzile futhi okuvumelana nemvelo.
Izakhiwo ze-graphite electrodezizenze zibe zilungele ukusiza ukusabela kwamakhemikhali okufunayo kanye nokwakheka komkhiqizo kumaseli e-electrolytic. Njengoba isidingo se-electrolysis sikhula kuzo zonke izimboni ezahlukene, ama-electrode e-graphite azoqhubeka nokudlala indima ebalulekile ekuvumela izinqubo ezisebenza kahle nezisimeme ze-electrochemical.
