PROCESS FOR REDUCING FLUORESCENCE IN PULP

摘要

The invention is directed to a method for reducing fluorescence in recycled pulp, wherein the method includes: contacting a pulp slurry containing fluorescent agents with chlorine dioxide; and contacting the pulp slurry with a sodium hypochlorite component, in an amount sufficient to reduce the fluorescence of the pulp; wherein the pulp is contacted with sodium hypochlorite component simultaneous with or after contact with chlorine dioxide.
