Abstract

Carbaryl was analyzed in olive oil using solid phase extraction (SPE) with lanthanum silicate as a new solid sorbent followed by high performance liquid chromatography with UV-VIS detection (HPLC-UV). The various parameters influencing extraction such as different eluents, volumes of eluent, conditioning pH and several spiked concentrations were studied to determine the optimum conditions for lanthanum silicate- SPE. Mean recovery with methanol as eluent was 76% with RSD 2-3% in concentration range of 0.5-32 ppm. The limit of detection (LOD= 1.03 mg kg-1) was lower than maximum residue limit (MRL) established by WHO/FAO.
