Kedu usoro ọgwụgwọ a na-ahụkarị maka cyanide - nwere mmiri mkpofu?

N'ọnọdụ dị ugbu a nke na-aga n'ihu na-emeziwanye ọkwa nchịkwa gburugburu ebe obibi na-achọwanye mkpa, ọtụtụ mpaghara na-eji cyanides mepụta nnukwu mmiri mmiri mkpofu na-emerụ ahụ. Ọ bụrụ na ejighi ya nke ọma, ọ nwere ike ibute ahụike mmadụ n'ihe egwu. Iji nweta ebumnobi abụọ nke na-abụghị ihe efu na enweghị mmerụ ahụ, Ụzọ imegharị ihe enwere ike ịnabata iji dozie okwu a.

Usoro acidification

Isi ụkpụrụ nke usoro a bụ ịgbakwunye sulfuric acid na cyanide - nwere mmiri mkpofu dị ka sodium cyanide mmiri na-ekpo ọkụ ma gbanwee pH ka ọ bụrụ 1.5. Nke a na-atụgharị CN - ka ọ bụrụ HCN. Ebe ọ bụ na ebe esi mmiri HCN dị oke ala, naanị 26.5 ℃, ọ nwere ike ịgbanarị ihe ngwọta na ụlọ okpomọkụ. A na-ewebata gas HCN gbapụrụ agbapụ n'ime onye na-etinye ihe ma tinye ya na ngwọta alkaline (sodium hydroxide ma ọ bụ calcium hydroxide ngwọta). N'ihi ya, a na-enweta 20% - 30% cyanide ngwọta, nke nwere ike ịmegharị ya.

Ion - Usoro mgbanwe

Anion - resins mgbanwe nwere njikọ siri ike maka metal dị iche iche - cyanide complex ion na cyanide - nwere mmiri mkpofu. Site na usoro nke adsorption na desorption. Cyanides enwere ike iwepụ ọla ndị bara uru na mmiri mkpofu. Uru nke usoro a bụ na mmiri dị ọcha dị mma ma kwụsie ike. Otú ọ dị, anion - mgbanwe resins nwere obere urughuru nha na ezughi oke n'ibu ike. Ọzọkwa, usoro ahụ dị mgbagwoju anya, yana nnukwu ọrụ siri ike na ọnụ ahịa dị elu.

Ụzọ mgbasa ozi Carbon arụnyere

Carbon na-arụ ọrụ nwere usoro microporous bara ụba yana hydrophobicity elu, yana ọ nwere njikọ siri ike maka ihe ndị na-egbu egbu na mmiri. Ya mere, usoro mgbasa ozi carbon na-arụ ọrụ bụ otu n'ime ụzọ kachasị dị irè maka iwepụ ihe ndị na-egbu egbu dị ala na mmiri. Mmetụta mgbasa ozi nke carbon na-arụ ọrụ na-adabere n'ọtụtụ oghere dị n'ime ya na nnukwu akụkụ elu ya.

Iji hụ na cyanide dị ka sodium cyanide agbapụtabeghị, ndị nyocha na-enyocha ogo mmiri mgbe niile iji chọpụta oke mmetọ cyanide. Ọ bụrụ na ọ dị mkpa, a na-agbasapụ mpaghara ịdọ aka ná ntị. Ma ndị nyocha na ndị ọrụ na-ahụ maka saịtị kwesịrị iyi mmanụ rọba - uwe mkpuchi na-eguzogide ọgwụ.

Na mmechi, kwesịrị ekwesị ọgwụgwọ na recycling nke Mmiri mmiri na-ekpofu Cyanide dị oke mkpa maka nchekwa gburugburu ebe obibi na nchekwa akụ. Site n'itinye usoro ndị a na ịhụ nleba anya siri ike, anyị nwere ike ibelata mmetụta ọjọọ nke cyanide - nwere ihe mkpofu na gburugburu ebe obibi na ahụike mmadụ.
