Long-term excessive uptake of fluoride through potable water will cause adverse effects on human health. Therefore, it is of great significance to detect and remove excessive fluoride in potable water. Here, we reported a multi-functional Zr-based coordination polymer namely CP-1, which could realize the visual detection and effectively selective adsorption of fluoride. The investigation of fluoride adsorption manifested that the maximum fluoride adsorption capacity of CP-1 could reach 48.78 mg g
−1 and selective adsorption capacity kept stable in a wide range of pH. By fluorometric approaches, the detection of limit of F− could achieve 1.55 × 10–6 mol L−1 based on CP-1. Moreover, the fluorescence test paper fabricated by in situ growth of CP-1 onto the surface of filter paper was proved to realize the visual detection of fluoride. [ABSTRACT FROM AUTHOR]- Published
