Its high-capacity and strong-acid-resistance were proved. In the acid condition, the adsorption efficiency to acide green 6B and direct fast yellow RL reached above 90%. Through the adsorption rate curve on adsorption behavior of the three dyes, they were all according with pseudo-secondary adsorption rate curve. The rate constant of adsorption increased with increasing temperature. Through the adsorption isotherm of the three dyes, acide green 6B and direct fast yellow RL were according with Langmuir equation, while disperse blue 56 was according with Freundlich equation. The adsorption behavior was an endothermic process. Entropy was increasing during the adsorption. So raising temperature was in favor of adsorption.
