Nws muaj peb txoj kev tseem ceeb:
1. Nws yog tsim los ntawm kev ua ntawm manganese dioxide thiab sulfuric acid.
2. Khoom cua ntawm cov hlau manganese thiab sulfuric acid
3. Lub by-product khib nyiab kua los ntawm hydroquinone ntau lawm muaj manganese sulfate thiab ammonium sulfate. Cov khib nyiab ua kua yog qhov nruab nrab los ntawm cov kua qaub ua kom tshem tawm cov khoom tsis huv, thiab tom qab ntawd cov kua tshuaj manganese sulfate rau deamination yog rhuab, thiab tom qab ntawd mloog zoo, crystallized, dehydrated, sib cais, qhuav, thiab ntim tau txais manganese sulfate Cov khoom tiav.
