Fig. 7From: Insight into the evolution of the proton concentration during autohydrolysis and dilute-acid hydrolysis of hemicelluloseA evolution of pH under prehydrolysis conditions. To help understand this, we related the lowest initial pH experiments to the added acid: series 17 0.25 % (wt/wt) and series 18 0.5 % (wt/wt)Back to article page
