Yooj yim paub qhov txawv ntawm ferrovanadium thiab ferromolybdenum
1. Saib qhov ceev. Qhov ceev ntawm ferromolybdenum yog siab dua li ntawm ferrovanadium. Rau tib lub ntim, ferromolybdenum hnyav dua.
2. Saib cov hlau nplaum. Ferrovanadium tsis yog hlau nplaum, tab sis ferromolybdenum yog hlau nplaum.
3. Saib cov nplaim taws ntawm polishing. Lub sparks ntawm ferrovanadium polishing yog ci thiab forked. Lub sparks ntawm ferromolybdenum polishing yog me me, tsis forked, thiab txawm lub sparks tsis pom.
4. Siv dilute nitric acid kom paub qhov txawv thiab txheeb xyuas. Ferrovanadium thiab concentrated nitric acid tuaj yeem ua rau ua kom muaj xim xiav vanadium dioxide thiab nitrogen dioxide roj. Ferromolybdenum thiab dilute nitric acid yuav hnov mob tam sim ntawd, thiab cov npuas daj yuav tshwm sim thaum pib, thiab thaum kawg muaj cov tshuaj xiav tsaus yuav raug tsim tawm ntawm qhov chaw.
5. Spectrometer. Nws tuaj yeem kuaj xyuas tag nrho cov nyiaj ntawm vanadium thiab molybdenum hauv nws.
