The bleaching mechanism of Sodium Percarbonate

   Sodium Percarbonate is high active oxygen carrier and has good solubility in cold water; it in water can be decomposed into Na2CO3 and H2O2. The sodium carbonate solution is one kind of basic liquid; and in basic condition, the oxydol will be changed into H2O and O. The formula is:

         H2O2★H++HOO- 2HOO-★O2●+2OH-

   HOO- is one kind of bleaching group, but it can be decomposed by metal ion and lower the bleaching effect of oxydol; HOO- is more stable in basic condition, and the 10 to 11 of PH value is helpful to the bleaching of textile. The Ph value of 1% -3% sodium carbonate solution is 10.5 to 11 which is good for the bleaching of paper pulp either. Otherwise, Sodium Percarbonate can be reductant when there is strong oxidizer existing.
