Solvent extraction used routinely for the preconcentration of carbamate herbicides from drinking water was replaced by sorption on the solid sorbent Separcol SI C18 T. Various factors of the preconcentration step that can affect the results of analysis were examined. Real drinking water samples contaminated by phenmedipham were analyzed by RP-HPLC in optimized conditions.
