Cellulose peak decreased such as C-1 of cellulose at 104.6 ppm, C-4 (crystalline region) of cellulose at 88.4 ppm, C-4 (amorphous regions) of cellulose at 83.1 ppm, C-3/C-2/C-5 of cellulose at 74.6 ppm, C-6 of cellulose at 64.5 ppm, showing that alkalescent salt and cellulose reacted and its crystalline structure destructed.
Meanwhile, alkalescent polyphosphate also had the function to increase the pH value (Baublits et al., 2005).
