Ngwọta Mberede dị irè maka mkpofu sodium Cyanide

Sodium cyanide bụ ihe na-egbu egbu nke ukwuu nke a na-ejikarị eme ihe n'ọtụtụ usoro ọrụ mmepụta ihe, gụnyere igwu ala na imepụta kemịkalụ. Mwepụta sodium cyanide na mberede nwere ike iwepụta hydrocyanic acid (HCN) na cyanide ion (CN-), nke na-etinye nnukwu ihe egwu nye ahụike na gburugburu ebe obibi. Mgbe ihe ndị dị otú ahụ mere, ụzọ nzaghachi mberede dị mkpa n'oge na nke dị irè iji belata ihe egwu ndị metụtara ikpughe cyanide. N'ebe a, anyị na-akọwapụta ụzọ atọ a na-ejikarị eme ihe maka nzaghachi mberede: alkaline chlorination, acid-base neutralization, na complex absorption.

1. Usoro chlorination alkaline

Nhicha alkaline bụ otu n'ime ụzọ kachasị dị irè maka ịgwọ nsị Sodium Cyanide . Usoro a na-eji ihe ndị na-ebelata ion cyanide, nke nwere ike ime ka oxidizes dị ike. Ihe ndị a na-ejikarị eme ihe n'ụzọ a gụnyere ntụ ọcha ( calcium hypochlorite ) na sodium hypochlorite.

Mgbe oxidants ndị a batara na ion cyanide, mmeghachi omume kemịkalụ na-eme nke na-agbanwe CN na-egbu egbu n'ime ihe ndị na-adịghị egbu egbu dị ka carbon dioxide (CO2) na nitrogen (N2). Ntughari a na-ewepụ nsí nke cyanide n'ụzọ dị irè, na-eme ka ọ bụrụ enyi na gburugburu ebe obibi.

Usoro a na-achọ ọnọdụ a na-achịkwa nke ọma iji hụ na oxidation zuru oke ma gbochie ịmepụta ogige ndị na-egbu egbu n'etiti. Ndị na-aza ajụjụ ga-enyocharịrị mmeghachi omume ahụ ma soro usoro nchekwa iji zere nsonaazụ ọ bụla na-atụghị anya ya.

2. Usoro neutralization acid-base

Ụzọ ọzọ a na-ejikarị emeso mwụfu Sodium cyanide bụ neutralization nke acid-base. Usoro a na-eji acidity adịghị ike nke hydrocyanic acid eme ihe, nke enwere ike iwepụ site na ntọala siri ike. Ihe ndị a na-ahụkarị gụnyere mmiri limewater (calcium hydroxide), soda caustic (sodium hydroxide), na amonia (ammonium hydroxide).

Mmeghachi omume neutralization na-emepụta nnu eke na-adịghị agbanwe agbanwe nke na-enyere aka ịchịkwa hydrocyanic acid. Otú ọ dị, ekwesịrị iburu n'uche na ngwọta mmiri na-esi na ya pụta ka na-egbu egbu nke ukwuu na a ga-achịkọta ya na nhazi ọzọ iji hụ na nchekwa.

Tụkwasị na nke ahụ, a ghaghị ịkwụ ụgwọ nlebara anya na ịchịkwa mgbasa nke ngwọta nkwụsịtụ, n'ihi na carbon dioxide na ikuku nwere ike dochie cyanide na ngwọta mmiri, nke nwere ike ịkpata mmetọ nke abụọ. Ya mere, ndị nnapụta ga-emejuputa usoro nchịkwa siri ike iji gbochie mgbasa nke ihe ndị na-egbu egbu.

3. Usoro absorption mgbagwoju anya

Usoro absorption dị mgbagwoju anya dabere na ihe onwunwe nke ion cyanide nwere ike ịmepụta ogige nwere ụfọdụ ion ígwè (dị ka ọlaọcha na ọla kọpa). Mgbe ion cyanide zutere ion ígwè ndị a, a na-emepụta ogige ndị na-adịghị egbu egbu, dị ka ogige cyanide ọlaọcha na ụlọ cyanide ọla kọpa.

Usoro a na-eji carbon arụ ọrụ dị ka onye na-ebu ion ígwè. Mgbe ọlaọcha ma ọ bụ ọla kọpa cyanide na-ejikọta ya na elu nke carbon a na-arụ ọrụ, ha nwere ike imeghachi omume na hydrocyanic acid ka ọ bụrụ ihe siri ike, nke na-adịghị egbu egbu, nke na-abụghị nanị na-enyere aka detoxification kamakwa na-enwe mmetụta nke na-ekpochapụ ebe ahụ emetụtara.

Nchekwa nchekwa na ihe mgbochi

Na mgbakwunye na usoro ọgwụgwọ ndị a dị n'elu, ọ dịkwa oke mkpa ka ị kpachara anya maka nchekwa ma ọ bụrụ na mmiri nwere sodium cyanide. Nke mbụ, ndị ọrụ nnapụta kwesịrị ịkwaga cyanide ọ bụla na saịtị ihe mberede ahụ gaa na ebe nchekwa iji gbochie mmebi nkwakọ ngwaahịa na mmetọ gburugburu ebe obibi na-esote.

Ọ bụrụ na ọkụ cyanide dị, ndị nnapụta kwesịrị iji mmiri na-agba agba agbanyụ ọkụ. Ọ dị mkpa iji zere iji acidic ma ọ bụ alkaline na-ekpochapụ ihe n'ihi na ha nwere ike ime ka ọnọdụ ahụ ka njọ ma mee ka ntọhapụ nke gas ndị na-egbu egbu.

Na mgbakwunye, mgbe hydrogen cyanide na-agbapụta, a machibidoro iwu iji usoro ịgbasa mmiri atọ n'otu n'otu maka mkpochapụ, n'ihi na usoro a nwere ike ime ka ihe ndị na-egbu egbu bụrụ ikuku ikuku, na-abawanye ohere ikpughe nke ndị ọrụ na gburugburu ya.

na ngwụcha

Mwụfu sodium cyanide chọrọ usoro nzaghachi mberede ngwa ngwa ma dị irè iji chebe ahụike mmadụ na gburugburu ebe obibi. chlorination alkaline, neutralization-base neutralization, na mgbagwoju anya absorption bụ ụzọ ọgwụgwọ atọ a na-ahụkarị nke nwere ike ibelata ihe ize ndụ ndị metụtara mkpughe cyanide.

Agbanyeghị, ndị na-aza ajụjụ ga-agbaso ụkpụrụ nchekwa ma mejuputa usoro njide iji gbochie mmetọ nke abụọ ma hụ na nchekwa nke ndị ọrụ niile tinyere aka na mbọ nzaghachi. Site n'ịghọta na iji ụzọ nzaghachi mberede ndị a, ụlọ ọrụ nwere ike ịkwado ma meghachi omume na nsị sodium cyanide, n'ikpeazụ na-ebelata ohere nke mmerụ ahụ.
