A water-compatible dummy molecularly imprinted resin (MIR) was synthesized in water using melamine, urea, and formaldehyde as hydrophilic monomers of co-polycondensation. A triblock copolymer (PEO-PPO-PEO, P123) was used as porogen to dredge the network structure of MIR, and N-(1-naphthyl) ethylenediamine dihydrochloride, which has similar shape and size to the target analytes, was the dummy template of molecular imprinting. The obtained MIR was used as the adsorbent in a green miniaturized solid-phase extraction (MIRâ¬mini-SPE) of plant growth regulators, and there was no organic solvent used in the entire MIRâ¬mini-SPE procedure. The calibration linearity of MIRâ¬mini-SPEâ¬HPLC method was obtained in a range 5â¬250ngmL(â1) for IAA, IPA, IBA, and NAA with correlation coefficient (r) â°¥0.9998. Recoveries at three spike levels are in the range of 87.6â¬100.0% for coconut juice with relative standard deviations â°¤8.1%. The MIRâ¬mini-SPE method possesses the advantages of environmental friendliness, simple operation, and high efficiency, so it is potential to apply the green pretreatment strategy to extraction of trace analytes in aqueous samples.
