摘要
A rapid, single stage process for the bleaching of high yield lignocellulose pulp (mechanical pulp) to enhanced brightness levels with hydrogen peroxide in the presence of magnesium sulphate and sodium silicate, with a substantial reduction in the wasteful, non-bleaching reactions of hydrogen peroxide. The residual hydrogen peroxide liquor may be recycled to a pulping or bleaching process.
