Fig. 3. Effect of polyethylene glycol (PEG; molecular weight = 2000) on the 2,4-dichlorophenol (2,4-DCP) removal by horseradish at varying concentrations of 2,4-DCP and H₂O₂. Reaction mixture volume = 5 mL; horseradish amount = 0.02 g; ratio of 2,4-DCP to H₂O₂ concentrations (mM) = 1:1; PEG concentration = 0.1 g/L; pH = 7.0; incubation time = 3 h; incubation temperature = 25°C.
