Table 2.

Experimental data for the determination of spectra reported in Figure 4. The V_1b and V_PQ volumes refer to an initial 1b solution with a concentration of 50.7 μg L⁻¹ and paraquat, PQ, solution with a concentration of 1000 μg L⁻¹, respectively. The final volume of each solution was made up to a total volume of 4000 μL by fixing with the solvent mixture.
