Kodi njira zochiritsira zodziwika bwino za cyanide - zomwe zili ndi madzi otayira ndi ziti?

Pakalipano pakupititsa patsogolo kayendetsedwe ka kayendetsedwe ka chilengedwe ndi zofunikira zowonjezereka, madera ambiri omwe amagwiritsa ntchito cyanides kupanga kwambiri kuchuluka kwa zoipa zinyalala zamadzimadzi. Ngati sichigwiritsidwe ntchito moyenera, chikhoza kukhala pachiwopsezo ku thanzi la munthu. Kukwaniritsa zolinga ziwiri zosawononga komanso zosavulaza, Njira zobwezeretsanso zitha kutengedwa kuti zithetse vutoli.

Njira ya Acidification

Mfundo yaikulu ya njirayi ndi kuwonjezera sulfuric acid cyanide - okhala ndi madzi oipa monga Sodium cyanide madzi otayira ndikusintha pH kukhala pafupifupi 1.5. Izi zimatembenuza CN - kukhala HCN. Popeza malo otentha a HCN ndi otsika kwambiri, ndi 26.5 ℃ okha, amatha kuthawa yankho kutentha kutentha. Mpweya wa HCN wotuluka umalowetsedwa mu chotengera ndikumwedwa ndi njira ya alkaline (sodium hydroxide kapena calcium hydroxide solution). Zotsatira zake, yankho la 20% - 30% la cyanide limapezeka, lomwe lingathe kubwezeretsedwanso.

Ion - Kusinthana Njira

Anion - ma resin osinthira amakhala ndi mgwirizano wamphamvu wazitsulo zosiyanasiyana - ma cyanide complex ions mu cyanide - okhala ndi madzi oyipa. Kupyolera mu njira za adsorption ndi desorption, Cyanides ndi zitsulo zamtengo wapatali m'madzi otayira zimatha kuchotsedwa. Ubwino wa njirayi ndikuti madzi oyeretsedwa ndi abwino komanso okhazikika. Komabe, ma anion - resins osinthanitsa amakhala ndi tinthu tating'onoting'ono komanso mphamvu zamakina osakwanira. Komanso, ndondomekoyi ndi yovuta kwambiri, ndipo imakhala yovuta kwambiri komanso yokwera mtengo.

Njira Yopangira Carbon Adsorption

Mpweya wopangidwa ndi activated uli ndi mawonekedwe olemera a microporous ndi pamwamba pa hydrophobicity, ndipo uli ndi mgwirizano wamphamvu kwambiri wa zinthu zapoizoni m'madzi. Chifukwa chake, njira ya activated carbon adsorption nthawi zonse yakhala imodzi mwa njira zothandiza kwambiri zochotsera zinthu zomwe zili ndi poizoni m'madzi. Mphamvu ya adsorption ya carbon activated makamaka imadalira ma pores ake ambiri amkati ndi malo akuluakulu enieni.

Kuonetsetsa kuti cyanides monga Sodium Cyanide sichinawukhire, oyendera amayesa kuchuluka kwa madzi kuti adziwe kuchuluka kwa kuipitsidwa kwa cyanide. Ngati ndi kotheka, malo ochenjeza amakulitsidwa. Oyang'anira ndi ogwira ntchito pamalopo ayenera kuvala mafuta a rabara - magolovesi oteteza osamva.

Pomaliza, chithandizo choyenera ndi kubwezeretsanso kwa Cyanide zinyalala zamadzimadzi ndizofunika kwambiri pachitetezo cha chilengedwe komanso kusunga zinthu. Pogwiritsa ntchito njirazi ndikuwonetsetsa kuti tikuyang'anitsitsa, titha kuchepetsa zotsatira zoipa za cyanide - zomwe zimakhala ndi zinyalala pa chilengedwe ndi thanzi la anthu.
