On the deciduous lignine inactivation influence on sulfite digestion at the pH increased values
The influence of preliminary treatment by buffer solutions at the increased рН values on the subsequent sulfite digestion has been studied. Preliminary treatment by buffer solutions in the pH range of 1.8-10.5 has been shown to inhibite the subsequent bisulfite digestion and not to practically act on the sulfite alkaline digestion. The preliminary treatment only at pH of 10.5 resulted in the essential inhibition of neutral sulfite digestion while the preliminary treatment by buffer solutions with the pH of 1.8 and 4.1 resulted in acceleration of next delignification.
