摘　要　针对彩色办公废纸脱墨浆的特点，选用了几种漂剂(h2o2、保险粉、fas)，研究了其漂白与脱色效果。结果表明，保险粉的脱色效果最好，fas的漂白能力最佳。从漂白和脱色两方面分析，fas是处理彩色办公废纸脱墨浆的首选药剂。在此基础上，对影响fas漂白与脱色效果的诸多因素进行了研究，并优选出最佳适用条件。关键词　彩色办公废纸　脱墨浆　漂白　脱色　二氧化硫脲bleaching and decolorizing for deinked pulp of colored office wastehou yanzhao　sun laihong　he zhibin　liu yufeng(pulp and paper industrial research institute of china，beijing，100020)abstract　bleaching and decolorizing of deinked pulp of colored office waste by using several bleaching agents were investigated .the results showed that the decolorizing effect of sodium hydrosulfite was the best and the bleaching ability of fas was the highest. fas which possessed both bleaching and decoloring abilities， was the best agent for treatment of deinked pulp of colored office waste. the factors affecting bleaching and decoloring ability of fas were studied， the best practical condition was optimized.keywords　colored office waste，deinked pulp，bleaching，decolorizing，fas侯彦召(中国制浆造纸工业研究所，北京，100020)孙来鸿(中国制浆造纸工业研究所，北京，100020)何志斌(中国制浆造纸工业研究所，北京，100020)刘玉凤(中国制浆造纸工业研究所，北京，100020)
