【Molecular Formula】: FeSO4 · 7H2O
Molecular Luj: 278.05
【Basic Properties】: Ntuj xiav los yog ntsuab monoclinic crystals, los yog crystalline hmoov. Tus txheeb ze ntom ntom 1.8987, melting point 64 degree. Tsis muaj ntxhiab, astringent. Yooj yim effloresces thaum raug huab cua, tig mus rau hauv cov hmoov dawb ntawm qhov chaw. Yooj yim oxidizes nyob rau hauv cov huab cua ntub, ua ib tug brownish - daj yooj yim ferric sulfate rau saum npoo. Soluble hauv dej thiab glycerol, insoluble hauv cawv. Nws txo cov khoom; ntawm 56.6 degree, nws hloov los ntawm heptahydrate mus rau tetrahydrate, ntawm 64.6℃mus rau monohydrate, ntawm 90℃nws poob rau molecules ntawm crystallization, thiab ntawm 300℃nws poob tag nrho nws cov dej ntawm crystallization los ua anhydrous. Thaum liab- kub, nws decomposes tso tawm SO2 thiab SO3. Corrosive. Fluorescent hauv huab cua qhuav. Daim ntawv tsis muaj dej yog hmoov dawb, tig xiav -ntsuab thaum cov tshuaj tiv thaiv nrog dej.
【Cov Khoom Siv】: Ferrous sulfate muaj cov teebmeem flocculation zoo heev li flocculant thiab muaj peev xwm decolorization zoo. Dhau li ntawm flocculation, nws kuj decolorizes, tshem tawm hnyav hlau ions, tshem tawm roj, tshem tawm phosphorus, thiab sterilizes. Nws yog tshwj xeeb tshaj yog zoo rau decolorizing thiab tshem tawm COD los ntawm dyeing thiab luam ntawv cov dej khib nyiab, thiab rau ferrite co- nag lossis daus hauv electroplating wastewater. 2. Ferrous sulfate kuj siv tau los ua zaub mov additive, pigment, raw khoom rau electronics kev lag luam, hydrogen sulfide deodorizer, av txias, foliar fertilizer, thiab industrial catalyst.
