ABSTRACT
In recent years, along with the extensive application of ciprofloxacin (CIP), it has gradually become one of key environmental issues to be solved urgently. A novel fluorescent responsive nanocellulose composite film was successfully prepared by combining TEMPO-oxidized cellulose nanofibers (TOCNF) and terbium coordination polymer (Tb-AMP), in aqueous medium at room temperature via in-situ synthesis to detect CIP. CIP could supply energy for terbium ion through antenna effect to achieve the green fluorescence of Tb-AMP@TOCNF under 365 nm UV lamp. The transparency of the Tb-AMP@TOCNF was 88% when the deposition ratio of Tb-AMP on TOCNF was 7.2% and the environmental stability was good, which was conducive to fluorescent detection. As CIP concentration increased, the fluorescence intensity of Tb-AMP@TOCNF increased, and fluorescence intensity had a good linear relationship with CIP concentration in the range of 1-8 µM (y = 4.57 + 3.17x, R2 = 0.999, LOD = 0.0392 µM). It was a new way to realize future quantitative colorimetric analysis of pollutants.
