Abstract

Al³⁺ is commonly utilized in daily life, however, the excessive accumulation of Al³⁺ within organisms can result in severe health problems. Herein, a highly efficient fluorescent probe EC-HTC for Al³⁺ was synthesized through chemical modification of ethyl cellulose. This probe exhibited a significant fluorescence enhancement response to Al³⁺, and it interestingly also possessed an obvious aggregation-induced emission (AIE) effect. The detection limit of probe EC-HTC for Al³⁺ was as low as 0.23 μM, and its pH usage range was as wide as 5-10. The complexation ratio of EC-HTC with Al³⁺ was determined to be 1:1 based on Job's plot, which was further confirmed by ¹H NMR titration and HRMS analysis. Moreover, the probe EC-HTC was successfully employed for the determination of Al³⁺ in environmental and food samples. In addition, the probe EC-HTC compositing PS (polystyrene) electrostatic spun fiber membranes EHP with high specific surface area were prepared to achieve the rapid and portable detection of Al³⁺.
