Recoveries obtained for micropollutants (200 ng L−1 each), extracting 1000 mL of water (pH 7) with 8 mL of ethanol as solvent, during consecutive reuse cycles performed with the same multi-layer carbon-based cartridge (bottom: 25 mg of CX; top: 25 mg of MWCNT); n = 3 (RSD is represented as error bars).
