Degradation of Abamectin Using the Photo-Fenton Process

Figure 3

Multiple comparison tests for the different processes applied to abamectin removal. The same letters above the means for the different procedures indicates that statistically there were no differences between the procedures, using Tukey’s test at a 5% level of significance. Conditions: [H₂O₂] = 6.0 mmol L⁻¹; [Fe³⁺] = 0.5 mmol L⁻¹; abamectin = 9.0 mg L⁻¹; λ = 365 nm; initial pH = 2.5.
