Decolorization of Anthraquinonic Dyes from Textile Effluent Using Horseradish Peroxidase: Optimization and Kinetic Study

Figure 1

Time course of decolorization of AV 109 (circle) and AB 225 (square) dyes at concentration of 30 mg/L. Other reaction conditions for AV 109 dye: peroxide concentration 2 mM, pH 5.25, enzyme concentration 0.15 IU/mL, temperature 24°C; for AB 225 dye: hydrogen peroxide concentration 1 mM, pH 5.5, enzyme concentration 0.04 IU/mL, and temperature 24°C.
