Cov txheej txheem ntub dej siv ferrous sulfate los yog ferrous nitrate, ferric sulfate, thiab ferric nitrate ua raw cov ntaub ntawv, thiab siv cov txheej txheem ntawm cov hlau oxide liab ua ntej npaj cov noob siv lead ua thiab tom qab ntawd oxidizing los npaj cov hlau liab. Cov khoom siv raw tuaj yeem yog ferrous sulfate, ferrous nitrate khoom raw khoom, los yog cov tshuaj aqueous uas muaj ferrous sulfate, ferrous nitrate, ferric sulfate, thiab ferric nitrate. Tus neeg sawv cev nruab nrab siv tuaj yeem yog cov ntawv hlau, cov ntaub ntawv hlau, lossis alkali lossis ammonia.
Nyob rau hauv xyoo tas los no, raws li kev siv tag nrho ntawm kev lag luam pov tseg, ib txoj hauv kev npaj cov hlau oxide liab muaj xim nrog titanium dioxide los ntawm - khoom ferrous sulfate los yog ferric sulfate tov, thiab siv steel zeb pickling khib nyiab acid los yog dej khib nyiab li. raw cov ntaub ntawv, tau tsim. Txhua yam yog nyob rau hauv qeb ntawm cov txheej txheem ntub dej. Tus neeg sawv cev nruab nrab siv tseem yog cov ntawv hlau, cov ntaub ntawv hlau, alkali lossis ammonia.
Qhov kom zoo dua ntawm cov txheej txheem ntub dej yog tias cov khoom tau txais tau zoo heev thiab kev ua tau zoo, thiab cov khoom sib txawv ntawm cov hlau oxide liab tuaj yeem npaj tau. Qhov tsis zoo yog tias cov txheej txheem ntws tau ntev, kev siv lub zog ntawm cov txheej txheem ntau lawm yog siab, ntau cov kua qaub pov tseg yog tsim, thiab tam sim no tsis muaj kev siv dav dav ntawm cov dej khib nyiab acidic.
