What is Optimizing pH for Hydrogen Peroxide Bleaching about?

This document discusses optimizing hydrogen peroxide bleaching of pulp by controlling pH. It finds that the rates of peroxide decomposition and bleaching reactions are strongly dependent on pH. Higher temperatures increase decomposition rates, lowering brightness and viscosity. The optimum pH balance maximizes bleaching reactions over decomposition. Experimental results on oxygen-delignified, chelated softwood kraft pulp show decomposition and bleaching rates vary significantly with pH and temperature. Main
