摘要：

Incorporation of sodium triphosphate to hydrated cellulose fibre decreases the temperature at which intense degradation of hydrated cellulose begins. primarily localized in not very ordered areas of HC, sodium triphosphate decreases the intensity of their thermal decomposition, and the processes related to intense degradation probably take place as in the more ordered (crystalline) areas. Sodium triphosphate is present in the carbonized residue (heat treatment temperature of 900 degrees C) in the form of NaPO3 (metaphosphate) and Na4P2O7 (pyrophosphate). The CF obtained in carbonization are promising as raw material for fabrication of sorption-active CFM.
