Description
Summary:[Display omitted] •Nanoporous silicon organosilicate (SiOCH) is used as a novel extraction phase.•Porous SiOCH offers higher extraction recoveries for PAHs than PDMS.•Microfluidic devices functionalized with porous SiOCH ensure extraction in 20min.•The nanoporous structure reduces matrix effects due to dissolved organic matter.•SiOCH coated lab-on-chips are promising alternatives to SBSE. This work reports on the improved performance using nanoporous organosilicate (SiOCH) for lab‐on-a-chip extraction of organic pollutants from natural waters. Validations were carried out for polycyclic aromatic hydrocarbons (PAHs) extraction, and the results were compared with the commonly used SBSE laboratory technique (Stir-Bar Sorptive Extraction). While a previous study performed with PDMS coated lab-on-a-chips had showed limitations for the most polar PAHs (log KOW
