## Abstract A novel approach for the sample pre‐treatment and determination of eight phenolic compounds in environmental water samples has been developed by hyphenating solid‐phase extraction (SPE) and liquid‐phase microextraction (LPME) techniques based on solid organic drop combined with gas chro
