Abstract

This study describes the design of an eco-friendly and low-cost reversed-phase dispersive liquid-liquid microextraction method based on reversed-phase dispersive liquid-liquid micelle-mediated microextraction (RPDLLMEM) for the extraction of carbendazim from edible oil samples and is coupled to batch injection analysis (BIA) with electrochemical detection using a boron-doped diamond electrode (BDDE). The highest extraction efficiency of carbendazim was achieved using sodium dodecyl sulfate (SDS). The factors that play an important role in the extraction were optimized using chemometric tools: SDS concentration (17.5 mM), pH of SDS solution (pH 7.0), vortex-assisted extraction time (60 s), and volume of SDS solution (900 mu L), using 5.0 mL of edible oil sample. An external analytical curve was constructed from 10.0 to 200.0 mu M (R2 = 0.996) and a LOD of 0.47 mu M was obtained. The proposed method was successfully applied to the analysis of soybean and canola samples and compared to HPLC-DAD. (AU)
