The Potential of Graphene as an Adsorbent for Five Pesticides from Different Classes in Rape Oil Samples Using Dispersive Solid-Phase Extraction

<div>Chromatograms of the extract of the blank rape oil sample (a), five standard pesticides (1 <i>µ</i>g/1 ml of methanol) (b), and the extract of the rape oil sample, spiked with the five standard pesticides (c) (concentration (62.5 ng/g) equal to LOQ). 1: metazachlor; 2: tebuconazole; 3: <i>λ</i>-cyhalothrin; 4: chlorpyrifos; 5: deltamethrin.</div>
