Biosorption of Acid Red R from Aqueous Solution by Acid-treated Penicillium sp
The biosorption of Acid Red R, from aqueous solutions by acid treated Penicilium sp. was studied in a batch mode. Operating variables like contact time, pH and initial dye concentration was investigated. The acid treated biomass exhibited maximum dye uptake at initial pH value of 3. The dye adsorption by the biomass was rapid process and the equilibrium was established in 60 min for 50 mg/L of initial dye concentration. Biosorption equilibrium data were fitted very well to the Langmuir as well as to the Freundlich adsorption model. According to the Langmuir model, the monolayer biosorption capacity of Penicillium sp. biomass was found to be 312.5 mg/g for Acid Red R at temperature of 30°C. The results indicate that the acid treated Penicilium sp. biomass can be used as an effective biosorbent to remove Acid Red R from aqueous solution.
