Abstract:In this study,waste beer yeast and sugarcane bagasse(SCB) were prepared to improve their adsorption capacity for cationic dyes: basic magenta.Experimental results showed that the adsorption capacity of the modified beer yeast and SCB were 528.1 and 736.5mg·g^-1,respectively,which were 3.3 and 7.6 times than the unmodified sorbents.Kinetic experiments showed that adsorption equilibrium could be obtained after 630 and 645 min for beer yeast and sugarcane bagasse(SCB),respectively.Ion strength experiments showed that it had little effects on the adsorption of dye when the concentration of co-ion K+ was lower than 0.1mol·L^-1.Results above indicated that the modified adsorbents had great potential in practical use.
Keywords:beer yeast  bagasse  basic magenta  PMDA
