| Abstract: | 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. |
