随着制浆造纸工业的不断发展以及环境问题的日益加剧,无氯或少氯漂白将逐渐替代传统含氯漂白。本文介绍了影响漂白及白度稳定性的主要金属离子,以及过渡金属离子在漂白过程中的危害和控制措施。
As the pulp and paper industry continues to evolve and environmental issues escalate, chlorine- or chlorine-less bleaching will gradually replace traditional chlorine-based bleaching. This article describes the main metal ions that affect bleach and whiteness stability, as well as the hazards and control measures of transition metal ions during bleaching.
