Abstract	A novel 8-hydroxyquinoline-based fluorescent and colorimetric chemosensor was designed, synthesized and fully characterized. The sensor showed high selectivity and sensitivity toward Al$^{3+}$ over other tested cations in EtOH/H$_{2}$O (1:99, v/v) medium. The increase in fluorescence intensity was linearly proportional to the concentration of Al$^{3+}$ with a detection limit of 7.38 × 10$^{−6}$ M. Moreover, the sensor exhibited an obvious color change from yellow to black in the presence of Fe$^{2+}$ and Fe$^{3+}$ in EtOH/THF (99:1, v/v) solution. The absorbance changes showed a linear response to iron ions with the detection limits of 4.24 × 10$^{−7}$ M and 5.60 × 10$^{−7}$ M for Fe$^{2+}$ and Fe$^{3+}$, respectively. Thus, this chemosensor provides a novel approach for selectively recognition of Al$^{3+}$, Fe$^{3+}$ and Fe$^{2+}$ among environmentally relevant metal ions.
