Determination of simazine and terbuthylazine in olive oil by high performance liquid chromatography with ultraviolet detector

An effective matrix solid-phase dispersion extraction for the determination of simazine and terbuthylazine in olive oil is described. The proposed methodology is based on partitioning liquid-liquid extraction and low temperature precipitation followed by matrix solid-phase dispersion (MSPD), using a...
