Fig. 6. The effect of chitosan gel on the 2,4-dichlorophenol (2,4-DCP) removal by horseradish. Reaction mixture volume = 10 mL; horseradish amount = 0.3 g enclosed between two 30- x 40-mm chitosan films of a total mass of about 100 mg (dry weight); 2,4-DCP concentration = 9 mM; H₂O₂ concentration = 18 mM; pH = 7.0; incubation time = 3 h; incubation temperature = 25°C.
