| 摘 要： | 过氧化氢已成为无元素氯（ECF）和全无氯（TCF）漂白的重要漂白剂，但在漂白过程中，浆中过渡金属离子的存在会引起过氧化氢发生无效分解产生游离基，并导致碳水化合物的降解，降低漂白效果。在漂白过程中适当加入些助剂，除去浆中的过渡金属离子，加强过氧化氢的漂白能力，来提高漂白效果，改善漂白工艺。

| Abstract: | Hydrogen peroxide has been an important oxidant in ECF and TCF bleaching sequences. However, the inefficient decompositions of hydrogen peroxide promoted by transition metal ions in pulp will produce hydroxyl radicals, which degrade carbohydrates and reduce the bleaching efficiency. To enhance the bleaching efficiency of H2O2 and improve the bleaching process, some bleaching additives were used to remove the transition metals. |
