Micellar Liquid Chromatographic Determination of Carbaryl and 1-Naphthol in Water, Soil, and Vegetables

Figure 1

Chromatograms showing the separation of carbaryl (1) and 1-naphthol (2) using the mobile phase 0.15 M SDS-6% (v/v) pentanol- 0.01 M NaH₂PO₄ (pH 3). The injected samples were (a) water (after 10 days being spiked with 500 ng mL⁻¹) and (b) soil (2 days after being spiked with 500 ng mL⁻¹).
