Pròiseas cinneasachaidh #sodiumsulfite
Tha sulfa is èadhar air an losgadh gus gas SO2 a ghineadh.
The SO2 gas reacts with a certain concentration of soda ash to generate sodium bisulfite.
Sodium bisulfite and caustic soda are neutralized to obtain #sodiumsulfite solution.
After concentration and centrifugation, a wet solid of #sodiumsulfite is obtained and dried. Then get the finished sodium sulfite
Tha am foirmle ath-bhualadh mar a leanas:
S + O2 = SO2
SO2 + Na2CO3 + H20 = NaHSO3
NaHSO3 + NaOH = Na2SO3 + H20
