EDTAD modified beer yeast and bagasse were prepared through a simple way. Adsorption experiment showed that the capacities of the modified beer yeast and bagasse for cationic dyes: basic magenta were 528.1 and 736.5 mg g-1, respectively, which were 3.3 and 7.6 times than the unmodified yeast and bagasse. And ionic strength experiment illustrated that it had little effect on the adsorption of dye when the concentration of coexistence ionic K+ was less than 0.1 mol L-1. The modified adsorbent had great potential in practical use.
