Biosorption of Acid Red from Aqueous Solutions onto Peanut Shell as a Low-cost

摘要：

　　Biosorption of Acid Red from aqueous solutions by peanut shell as a low-cost biosorbent was investigated as a function of initial pH,initial biomass concentration.The kinetics and equilibrium of biosorption were examined in detail.Three kinetic models (pseudo-first order,pseudo-second order,and internal diffusion order model) were used to connect data and to determine the kinetic parameters.Two well-known adsorption isotherms were chosen to describe the biosorption equilibrium.The experimental data were analyzed using two two-parameter models (Langmuir and Freundlich).The equilibrium biosorption isotherms showed that peanut shells possess high affinity and sorption capacity for Acid Red,maximum biosorption capacities of 9.8232mg/g.All results showed that peanut shells biomass is an attractive,alternative low-cost biosorbent for removal of heavy Acid Red from aqueous media.
