Ƙwayoyin cuta na iya ɗauke da sinadarai masu ɗauke da cyanide a saman sa, kuma cire su a gaba zai iya inganta ingancin magani na gaba da kuma hana lalacewar kayan aikin magani.

• Cire kakin zuma da danshi : Tunda iskar shaye-shaye na iya ƙunsar tururin ruwa da hazo mai, yi amfani da na'urorin cire danshi don cire waɗannan abubuwan. Tururin ruwa na iya shafar ingancin amsawar hanyoyin magani na gaba, kuma hazo mai na iya yin tasiri ga aikin abubuwan da ke haifar da maye da kuma sha.

3. Babban Tsarin Jiyya

• Hanyar Shayewar Sinadarai

• Ka'ida : Yi amfani da maganin alkaline kamar sodium hydroxide (NaOH) ko calcium hydroxide (Ca(OH)₂) a matsayin abubuwan sha. Cyanide a cikin iskar shaye-shaye yana amsawa da maganin alkaline don samar da gishirin cyanide. Misali, HCN yana amsawa da NaOH don samar da Sodium Cyanide (NaCN), wanda zai iya cire cyanide daga iskar shaye-shaye yadda ya kamata.

• Tsarin Aiki : Iskar shaye-shaye tana shiga hasumiyar shan sinadarai, inda take hulɗa da ruwan alkaline da aka fesa ta hanyar da ba ta dace ba. Hasumiyar shaye-shaye yawanci ana cika ta da kayan marufi don ƙara yankin hulɗa tsakanin iskar da ruwan, wanda ke inganta ingancin shaye-shaye.

• Hanyar Oxidation Catalytic

• Ka'ida : A ƙarƙashin aikin mai kara kuzari, cyanide a cikin iskar shaƙa yana oxidize zuwa Carbon dioxide (CO₂), ruwa (H₂O), da nitrogen (N₂). Masu kara kuzari na yau da kullun sun haɗa da masu kara kuzari na ƙarfe masu daraja (kamar platinum, palladium) da masu kara kuzari na ƙarfe (kamar titanium dioxide, vanadium pentoxide).

• Tsarin Aiki : Bayan wucewa ta hasumiyar shan sinadarai, iskar shaye-shaye tana shiga na'urar hada iskar shaye-shaye ta catalytic oxidation. Na'urar tana da gadon hada iskar shaye-shaye, kuma iskar shaye-shaye tana ratsawa ta gadon hada iskar shaye-shaye a wani yanayi na zafin jiki da saurin sarari. Mai hada iskar shaye-shaye yana inganta amsawar hada iskar shaye-shaye ta cyanide, yana rage gubarsa.

• Hanyar shayar da ruwa

• Ka'ida : Yi amfani da hasumiyar shaye-shaye mai ruwa don fesa mai shaye-shaye don shaye-shaye na cyanide a cikin iskar shaye-shaye. Mai shaye-shaye na iya zama maganin sinadarai na musamman da aka tsara bisa ga halayen cyanide.
