摘要：

Optical brightening agents (OBAs) can effectively improve the optical properties of high-yield pulp (HYP). We developed a new method for this purpose an found that the OBA brightening process can be conveniently incorporated into the alkaline peroxide bleaching process. By combining peroxide bleaching with an optical brightening agent, one can decrease the bleaching cost to reach the same brightness target. There are a number of advantages of adding OBA to HYP at the pulp mill over the conventional wet-end addition of OBA.
