Figure 1
Effect of organic solvent on pesticide’s extraction efficiency. Conditions of the donor phase: 15 mL of water spiked at 100 µg L−1 of each pesticide; extraction time of 60 min; and stirring speed of 100 rpm. Error bars represented the standard deviation of the mean peak area for replicates.
