Summary: Electro-enhanced solid-phase microextraction (EESPME) integrates solid-phase microextraction with the electric field, retaining the extraction performance of SPME while having the advantages of efficient electric field driving and special interaction between the electric field and material molecules. A novel fiber preparation strategy, using electropolymerization, was proposed to obtain highly conductive porphyrin-based covalent organic framework (POR-COF) fibers. The performance of the POR-COF fiber in EE-SPME of phthalate esters (PAEs) was evaluated, showing high selectivity and sensitivity in detecting trace PAEs in various samples. The controlled design and synthesis of highly conductive POR-COF fibers offer prospects in developing EE-SPME technologies.

Summary: A novel metal-organic framework (MOF)/covalent-organic framework (COF) heterostructure hybrid composite (NH2-UiO-66/TpPa-1-COF) was synthesized and applied as a photoelectrochemical (PEC) sensitized layer in a molecularly imprinted PEC sensor for sensitive determination of dibutyl phthalate (DBP). The NH2-UiO-66/TpPa-1-COF was prepared via a solvothermal method, demonstrating improved photocurrent response due to heterojunction formation and strong light absorption capacity. A molecularly imprinted polymer (MIP) was incorporated as the recognition component of the PEC sensor, enabling specific binding of DBP and decreased photocurrent response. The MIP-PEC sensor showed a wide detection range and good stability, selectivity, reproducibility, and applicability in real samples.

Summary: It is important to give traditional photocatalysis selectivity for a class of characteristic pollutants in environmental science. Using PAEs-TiO2 as a selective photocatalyst, 302.5 μg/L of 11 phthalic esters (PAEs) were preferentially removed to 4.94 μg/L in the presence of 10 mg/L of natural organic matter via specific hydrogen bonds or cation-pi interactions. The study provides new insights into the selective photocatalysis of pollutants with similar molecular structure.
