The effectiveness of novel activators in the hydrogen peroxide bleaching of white ledger was investigated. With the addition of 1 % sodium persulfate, 4% Prestogen EB, and thiourea(molar ratio to residual hydrogen peroxide=1/2) to hydrogen peroxide bleaching, the brightness of the bleached pulps increased by up to 2 ~ 3 points when compared to hydrogen peroxide bleaching with conventional activators. The effectiveness of the activators in enhancing the brightness was in the order of Prestogen EB, thioruea, sodium persulfate and silicates. The strengths of the pulps bleached by hydrogen peroxide with the novel activators were slightly lower or similar to those of the pulps bleached by conventional hydrogen peroxide. In particular, the addition of sodium persulfate produced a more marked decrease in the tensile index of the bleached pulp. Accordingly, sequential oxidative and reductive bleaching with the addition of thiourea to the residual hydrogen peroxide was found to be most effective in view of the bleaching chemical cost, brightness gains, and strength of the bleached pulps.
