摘要
常见的几种漂白剂如次氯酸钠、亚氯酸钠、过氧化氢等在漂白中会产生含氯有机副产物AOX ,对环境污染。文中介绍了一种AOX值较低的漂白剂———过醋酸 ,并对该漂白剂的漂白工艺进行了研究 ,确定了过醋酸漂白的最佳工艺条件 :漂白剂用量 8% ,漂白温度 70℃ ,pH值 7,漂白时间
In traditional bleaching processes with sodium hypochlorite, sodium chlorite and hydrogen peroxide, a chlorine contained organic by product AOX, an environmental pollutant always tend to be producd. An AOX less contained bleaching agent, peracetic acid is introduced. An optimized technological specification for peracetic acid bleaching is formulated based on the study of the said bleaching process: a dose of bleaching agent 8% should be given at a temperature of 70℃ and a pH value of 7 with a bleaching time of 6 minites.
