Indeed, lower NaOH concentrations
led to lower delignification levels for experiments that were
performed at the same temperature and sonication power (e.g., see
SA-AWB11 and SA-AWB12 in Table 3). Therefore, under a sonication
power of 105 W, the use of higher temperatures allowed theuse of lower NaOH concentrations, and 0.1875 g g−1 (or 0.94% NaOH
at 5 wt% TS) was enough to achieve the highest delignification level
under the conditions used in this study.
