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.
