Reusable UV-crosslinked MIL-101(Fe)@CQD/polymer nanocomposite films for fluorescence detection of As( iii ) in water

Year: 2026

Type: article

Abstract: . The method showed high tolerance toward the tested potentially interfering species, including As(v), Sb(iii), Sb(v), carbonate, bicarbonate, phosphate, and common metal ions. Practical applicability was evaluated using environmental water samples and certified reference materials for arsenic, yielding recoveries of 101.3-104.6% with relative standard deviations below 5%. Results for environmental water samples were consistent with direct HG-AAS performed without a separate As(v)-to-As(iii) pre-reduction step; this comparison was used as supporting evidence of analytical consistency rather than as proof of exclusive As(iii) detection. The same sensing film was reused over 150 measurement/regeneration cycles, with a 1.4% difference between the first and final responses. The combined MIL-101(Fe), CQD, and UV-curable polymer platform therefore provides an easy-to-handle and reusable solid-state format for trace As(iii) determination in aqueous samples.
