Njira Zatsopano Zobwezeretsanso Madzi a Zinyalala za Sodium Cyanide: Kuyika Kwambiri pa Kasamalidwe ka Zachilengedwe

As Kulinganiza kwa Chilengedwe Miyezo ikupitilira kukula, mafakitale akugwiritsa ntchito Sodium Cyanide akuyang'anizana ndi kachitidwe kawo kotayira zinyalala. Sodium cyanide, zomwe zimagwiritsidwa ntchito kwambiri popanga migodi ndi mankhwala, zimapanga madzi ambiri oopsa oopsa omwe, ngati atasamalidwa bwino, angayambitse thanzi la anthu komanso chilengedwe. Pofuna kuchepetsa zoopsazi, njira zosiyanasiyana zochiritsira zapangidwa kuti zibwezeretsedwe sodium cyanide kuwononga madzi bwino.

1. Njira ya Acid

Imodzi mwa njira zodziwika kwambiri zochiritsira Sodium cyanide zinyalala ndi njira acidification. Njira imeneyi imaphatikizapo kuwonjezera sulfuric acid m'madzi onyansa a cyanide, kusintha pH kukhala pafupifupi 1.5. Kusintha kumeneku kumathandizira kuti ma cyanide ions (CN-) asinthe kukhala hydrogen cyanide (HCN), mpweya wokhala ndi kuwira kochepa kwambiri kwa 26.5°C. Pa kutentha kwa chipinda, HCN ikhoza kuthawa yankho, kulola kusonkhanitsa kwake.

Mpweya womasulidwa wa HCN umalowetsedwa mu chotengera, momwe umatengedwa ndi sodium hydroxide kapena calcium hydroxide solution. Izi zimatulutsa cyanide solution, yomwe nthawi zambiri imayambira 20% mpaka 30%, yomwe imatha kubwezeretsedwanso kuti igwiritsidwe ntchito m'mafakitale. Ngakhale ili yothandiza, njirayi imafuna kugwiriridwa mosamala chifukwa cha poizoni wa HCN, zomwe zimafunikira kuti pakhale chitetezo chokhazikika kwa ogwira nawo ntchito.

2. Njira Yosinthira Ion

Njira ina yodalirika yobwezeretsa zinyalala za sodium cyanide ndi njira yosinthira ion. Izi zimagwiritsa ntchito ma anion exchange resins omwe amawonetsa kuyanjana kolimba kwa ma ion osiyanasiyana achitsulo a cyanide omwe amapezeka m'madzi onyansa. Kupyolera m'mizere ya ma adsorption ndi ma desorption, zonse cyanide ndi zitsulo zamtengo wapatali zimatha kuchotsedwa bwino mumadzimadzi.

Njira yosinthira ma ion imapereka mwayi wopanga madzi oyeretsedwa apamwamba kwambiri, zomwe zimapangitsa kukhala njira yabwino kwa mafakitale omwe akufuna kukwaniritsa malamulo okhwima a chilengedwe. Komabe, si kopanda mavuto ake. Ma resin a anion omwe amagwiritsidwa ntchito pochita izi amakhala ndi tinthu tating'onoting'ono ndipo amatha kukhala opanda mphamvu zokwanira zamakina, zomwe zimapangitsa kuti pakhale zovuta zogwirira ntchito. Kuonjezera apo, zovuta za ndondomekoyi komanso ndalama zomwe zimayenderana nazo zingalepheretse mafakitale ena kutengera njirayi.

3. Njira Yopangira Carbon Adsorption

Yoyambitsa Carbon Kulowetsa madzi m'thupi ndi njira ina yodziwika bwino yochizira zinyalala za sodium cyanide. Kapangidwe kake kapadera ka ma microporous ndi pamwamba powopa madzi m'thupi. Carbon Woyendetsa imapereka mphamvu yaikulu pa zinthu zapoizoni m'madzi, zomwe zimapangitsa kuti ikhale njira yothandiza yochotsera zinthu zodetsa zomwe sizimasungunuka kwambiri m'madzi.

Mphamvu ya activated carbon adsorption yagona mu netiweki yake yayikulu ya pore komanso malo akuluakulu apadera, omwe amathandizira kutsekeka kwa zinthu zovulaza. Njirayi ndiyopindulitsa makamaka kwa mafakitale omwe akufuna njira yodalirika komanso yothandiza yochotsera madzi oipa. Komabe, machitidwe a activated carbon amatha kutengera zinthu monga kuchuluka kwa zonyansa komanso kupezeka kwa zinthu zopikisana m'madzi onyansa.

4. Ndondomeko Zachitetezo ndi Kuyesa Kwanthawi Zonse

Mosasamala kanthu za njira yochira yogwiritsidwa ntchito, chitetezo chikadali chodetsa nkhawa kwambiri pakusamalira zinyalala za sodium cyanide. Ogwira nawo ntchito yochizira amayenera kutsatira malamulo okhwima otetezedwa, kuphatikiza kugwiritsa ntchito magolovesi oteteza mafuta osamva labala ndi zida zina zodzitetezera (PPE). Kuyesedwa pafupipafupi kwa madzi ndikofunikanso kuti zitsimikizire kuti zikutsatira malamulo a chilengedwe komanso kuyang'anira momwe njira zowathandizira zikuyendera.

Kuyezetsa kuyenera kuchitidwa ndi ogwira ntchito oyenerera omwe angathe kuwunika molondola kuchuluka kwa cyanide ndi zinthu zina zowopsa m'madzi otayidwa. Kuchita khama kumeneku sikumangoteteza thanzi la ogwira ntchito komanso kumathandiza kupewa kuipitsidwa kwa chilengedwe.

Kutsiliza

Pamene mafakitale akupitirizabe kulimbana ndi zovuta zomwe zimadza chifukwa cha zinyalala za sodium cyanide, kupititsa patsogolo ndi kukhazikitsa njira zothandizira kubwezeretsa ndizofunikira. Njira ya acidification, njira yosinthira ma ion, ndi activated carbon adsorption iliyonse imapereka zabwino ndi zovuta zapadera, ndikuwunikira kufunikira kwa njira yogwirizana ndi zomwe zimafunikira pakugwirira ntchito.

Poika patsogolo chitetezo ndi kutsata chilengedwe, mafakitale sangachepetse zoopsa zomwe zimagwirizanitsidwa ndi zinyalala za sodium cyanide komanso zimathandiza kuti tsogolo likhale lokhazikika. Pamene malamulo akuchulukirachulukira, kukhazikitsidwa kwa njira zatsopano zobwezeretsera kudzakhala kofunikira pakuwonetsetsa kuti kugwiritsa ntchito sodium cyanide kumakhalabe koyenera komanso kopanda chilengedwe.
