摘　　要：实验测定了酸性红 3B染料废水中酸性红 3B在粉煤灰中的吸附特性 ,研究了吸附温度、粉煤灰粒径及溶液pH值对吸附等温曲线的影响 ,得到了pH =6 8、2 5℃下的吸附等温表达式 ;考察了处理量、染料浓度、粒径等对粉煤灰固定床吸附处理酸性红The adsorptive characteristics of acid red 3B in coal ash are determined by experiments.The isothermal expression of adsorption in pH=6.8 and at 25℃ is obtained by studying the effects of the adsorptive temperature,the size of the coal ash and pH of the solution on the adsorptive isotherm.The influence law of the treating quantity,dye concentration and particle size on the penetration time of a coal ash fixed bed is also examined.
