摘　　要：论述了有机胺和无机铵盐及表面活性剂在碱法麦草浆次氯酸钠漂白中的助漂、减氯及提高白度的作用,研究了不同助剂用量对纸浆白度和残余有效氯的影响。研究结果表明:使用这些助剂可以明显地提高纸浆白度,节省漂白用氯量和减少漂白废液中残余有效氯的含量。In this article,the effect of amine(ammonium)salt and surfactant on chlorine reduction and the improvement of brightness in wheat straw bleaching with sodium hypochlorite was studied.Simultaneously,the influence of different dosage of those chemicals on pulp whiteness and residual chlorine was discussed.The result indicated that those chemicals could obviously raise pulp whiteness,remarkably reduce the usage of effective chlorine in the bleaching liquor and the content of residual chlorine in the effluent ,which means that the two chemicals mentioned above have the promoter function in bleaching and are beneficial to pollution reduction.
