Ihe ndabere nke Electrolytic Oxidation maka Cyanide - nke nwere mmiri mkpofu

Usoro oxidation Electrolytic maka ịgwọ mmiri mkpofu Sodium cyanide na-arụ ọrụ na ụkpụrụ nke iji ọkụ eletrik na-akwali mmeghachi omume kemịkalụ na anode na cathode, si otú a na-agbanwe cyanide dị na mmiri mkpofu ka ọ bụrụ ihe na-adịghị emerụ ahụ. N'ime usoro a, ma cyanide dị mfe na cyanide dị mgbagwoju anya dị na mmiri mkpofu na-agafe electrolysis.

Mmeghachi omume anode

• Maka Cyanide Dị Mfe : N'oge mmeghachi omume nke ọkwa mbụ na anode, cyanide dị mfe na-emeghachi omume nke ọma na ihe ndị ọzọ dị na mmiri mkpofu iji mepụta ihe na-adịghị egbu egbu. Na nkebi nke abụọ sochirinụ, mmeghachi omume abụọ na-eme. Otu mmeghachi omume na-ekewa ihe mejupụtara a ka ọ bụrụ Carbon dioxide, nitrogen, na mmiri. Mmeghachi omume nke ọzọ na-eme ka mmepụta ammonium pụta.

• Maka Nhazi Cyanide (Ịnara ọla kọpa - nke nwere mgbagwoju anya dị ka ihe atụ) : Mgbe njikọta cyanide, dị ka ọla kọpa - nke nwere mgbagwoju anya, rutere anode, ọ na-emeghachi omume iji mepụta ion ọla kọpa na ihe ọzọ na-adịghị egbu egbu. Mgbe etinyere nnu tebụl na ihe na-eme ka electrolytic dị na ya, mmeghachi omume ndị ọzọ na-eme. A na-eme ka ion chloride sitere na nnu ahụ dị ka oxidized iji mepụta chlorine ọhụrụ. Chlorine ọhụrụ a na-emeghachi omume na cyanide na ihe ndị ọzọ dị na mmiri mkpofu iji kewaa ngwakọta cyanide ka ọ bụrụ ngwaahịa na-adịghị emerụ ahụ, gụnyere carbon dioxide, nitrogen, na ion chloride.

Mmeghachi omume Cathode

Na cathode, ion hydrogen na-enweta electrons wee mepụta hydrogen gas. Maka metal - nwere ogige cyanide, dị ka ndị nwere ọla kọpa, ion ọla kọpa na-enweta electrons ma nwee ike idobe ya dị ka ọla kọpa. N'okpuru ọnọdụ ụfọdụ, ion ọla kọpa nwekwara ike iji ion hydroxide meghachi omume iji mepụta ọla kọpa hydroxide precipitate.

Ihe ndị dị mkpa na Usoro Oxidation Electrolytic

• Ihe Electrode : Nhọrọ nke ihe elektrọd dị oke mkpa. N'ọtụtụ oge, enwere ike iji ígwè dị nro mee ihe dị ka ihe katode. Agbanyeghị, anode kwesịrị iguzogide gburugburu ebe obibi elektrọkoloji siri ike. Anod siri ike (DSA), nke e ji ọla oxide dị mma mee ma ọtụtụ ụlọ ọrụ na-emepụta, dabara nke ọma maka ojiji a. Graphite nwekwara ike ịbụ ihe anode, mana ọ nwere nsogbu nke iji nwayọ nwayọ na-eri ya n'oge usoro elektrọklịs.

• Njikwa Okpomọkụ : Ọ dị mkpa ka a na-achịkwa okpomọkụ nke mmiri mkpofu n'oge electrolysis nke ọma. A na-edebe ya n'okpuru 25 Celsius. Ọ bụrụ na okpomọkụ ebili elu nke ukwuu, chlorine a na-emepụta site na oxidation nke ion chloride dị na nnu agbakwunyere ga-apụ tupu ọ nwee ike imeghachi omume na cyanide, si otú a na-ebelata arụmọrụ nke usoro mbibi cyanide.

• Mgbakwunye Chloride Ion : Ịtinye ion kloride na mmiri mkpofu nwere ike ime ka cyanide ghara ịdị ọkụ eletrik. Dịka ọ na-adịkarị, itinye 1-2 g/L nke ion kloride zuru ezu. N'ọnọdụ ụfọdụ, itinye nnu nkịtị (sodium kloride) na mkpokọta 25 g kwa lita na mmiri mkpofu egosila na ọ na-enyere aka nke ọma na mbibi electrolytic nke cyanide.

Uru nke Usoro Oxidation Electrolytic

• Ọrụ Dị Elu Maka Mmiri Mkpofu Dị Elu : Usoro oxidation electrolytic dị irè karịsịa maka ịgwọ mmiri mkpofu dị elu nke nwere cyanide, dịka ndị a na-ahụ n'ebe a na-egwupụta ọlaedo. Ọ nwere ike ibelata mkpokọta cyanide dị na mmiri mkpofu nke ukwuu.
