摘　　要：研究了麦饭石对水溶性染料直接耐酸大红4BS的吸附作用,探讨了搅拌时间、麦饭石粒度、投料量及溶液pH值等因素对吸附的影响。结果表明,麦饭石对染料的吸附能较好地符合Langmuir方程。且对染料溶液及实际废水具有良好的脱色率和COD去除率。Adsorption of direct acid-resisting red 4BS from aqueous solution by Maifan stone and its influential elements have been studied. The equilibrium data well met the Langmuir model of adsorption. Adsorption of dye from wastewater by Maifan stone also been studied. The result showed that Maifan stone has efficient decolorization and high removal rate of COD.
