ʻO ka Electrolysis o nā hopena Brine me ka hoʻohana ʻana i nā Ti Electrodes no ka hana ʻana i ka Chlorine

ʻO ke kaʻina hana o ka electrolyzing i kahi hopena brine me ka hoʻohana ʻana i nā electrodes titanium e hana i ka chlorine ua kapa pinepine ʻia ʻo "electrolysis of brine." Ma kēia kaʻina hana, hoʻohana ʻia nā electrodes titanium e hoʻomaʻamaʻa i ka hopena oxidation o nā ions chloride i loko o ka brine, e alakaʻi ana i ka hana ʻana o ke kinoea chlorine. ʻO ka hoʻohālikelike kemika holoʻokoʻa no ka hopena penei:

Ma kēia kaulike, hana ʻia nā ion chloride i ka oxidation ma ka anode, e hopena ana i ka hana ʻana o ke kinoea chlorine, ʻoiai e hoʻemi ʻia nā molekala wai ma ka cathode, e loaʻa ai ke kinoea hydrogen. Eia kekahi, hana ʻia nā ion hydroxide i ka hoʻemi ʻana ma ka anode, e hana ana i ke kinoea hydrogen a me ka sodium hydroxide.

ʻO ke koho ʻana o nā electrodes titanium ma muli o ke kūpaʻa maikaʻi loa o ka titanium i ka corrosion a me ka conductivity, e ʻae ana iā ia e hana paʻa i ka hopena i ka wā electrolysis me ka ʻole o ka corrosion. ʻO kēia ka mea e lilo ai nā electrodes titanium i koho kūpono no ka electrolysis o ka brine.

ʻO ka electrolysis o ka wai paʻakai e pono pinepine ai kahi kumu mana o waho e hāʻawi i ka ikehu no ka hopena electrolytic. ʻO kēia kumu mana he lako mana pololei (DC) no ka mea e pono ai nā hopena electrolytic i kahi kuhikuhi kūlike o ke kahe o ke au, a hiki i kahi lako mana DC ke hāʻawi i kahi kuhikuhi mau o ke au.

I ke kaʻina hana o ka electrolyzing wai saline e hana i ke kinoea chlorine, hoʻohana pinepine ʻia kahi lako mana DC haʻahaʻa-voltage. Pili ka voltage o ka lako mana i nā kūlana hana kikoʻī a me ka hoʻolālā lako, akā maʻamau ma waena o 2 a 4 volts. Eia kekahi, ʻo ka ikaika o kēia manawa o ka lako mana he mea koʻikoʻi ia e pono e hoʻoholo ʻia ma muli o ka nui o ke keʻena hana a me ka hua hana i makemake ʻia.

I ka hōʻuluʻulu manaʻo, ʻo ke koho ʻana o ka lako mana no ka electrolysis o ka wai paʻakai e pili ana i nā koi kikoʻī o nā hoʻokolohua a i ʻole nā ​​​​kaʻina hana ʻoihana e hōʻoia i ka hopena kūpono a me ka hoʻokō ʻana i nā huahana i makemake ʻia.
