Multiclass Pesticide Residue Analysis in Fruit and Vegetable Samples by Combining Acetone-Based Salting-Out Assisted Extraction with Dispersive Liquid-Liquid Microextraction

<div>Typical chromatograms at 210 nm and 235 nm. Spiked concentrations were 200 <i>µ</i>g/kg for atrazine, benalaxyl, chlorpyrifos, 4,4′-DDT, and bifenthrin and 400 <i>µ</i>g/kg for carbofuran. At each wavelength, A and B stand for unspiked and spiked chromatograms, respectively. Peak identification: (1) carbofuran; (2) atrazine; (3) benalaxyl; (4) chlorpyrifos; (5) 4,4′-DDT; (6) bifenthrin.</div>
