A modified QuEChERS method for the determination of some herbicides in yogurt and milk by high performance liquid chromatography

► A modified QuEChERS method was applied to extract herbicides in milk and yogurt. ► The modification of QuEChERS method was focused on extraction solvent. ► The expenditures of adsorbent and salt are low. ► The extraction and cleanup efficiency are high. ► The LODs for herbicides are lower than those obtained by the reference method.
