Carboxyl-functionalized poly(arylene ether sulfone)-terbium(III) coordination polymer-based fluorescent fibrous membrane for highly sensitive detection of Cr(VI) ions

Key Points

• The aim is to develop a fluorescent fibrous membrane for sensitive detection of toxic Cr(VI) ions.
• Synthesis of carboxyl-functionalized poly(arylene ether sulfone)-terbium(III) coordination polymer
• Fabrication of fibrous membranes incorporating the polymer
• Evaluation of the fluorescence response to Cr(VI) ions
• The membrane exhibited a high selective fluorescence response to Cr(VI) ions
• Detection limits reached lower concentrations of Cr(VI) compared to existing methods
• Demonstrated potential for real-world wastewater monitoring applications
