VOLUME 290 (2015) PAGES 23201–23213 PAGE 23205: The following sentence was incorrect. “The remaining reduction of W164S CI and CII is attributed to the phenolic units present in the lignosulfonates from softwood (2.1%) and hardwood (1.4%) lignosulfonates.” This should be corrected as follows. “The remaining reduction of W164S CI and CII is attributed to the phenolic units present in the lignosulfonates from softwood (phenolic hydroxyls, 2.1% of lignin weight) and hardwood (phenolic hydroxyls, 1.4% of lignin weight).” This correction does not affect the results or conclusions of this work.
