Herein, a rational combination of dispersive solid-phase sorbent and 2-(2, 4-Dihydroxyphenyl)-3, 5, 7-trihydroxychromen-4-one (morin) was proposed for sensitive and selective determination of Al 3+ ion. Nickel ferrite nanospheres (NiFe 2 O 4 NS) functionalized with morin was used to preconcentrate and estimate Al 3+ via the formation of fluorescent complex at pH 7.0. The functionalization was assisted by anionic surfactant sodium dodecyl sulphate (SDS) and ultrasonication. The results revealed that the fluorescence intensity of Al-morin/SDS@ NiFe 2 O 4 NS is higher than Al-morin. Functionalization of NiFe 2 O 4 NS with morin was confirmed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), powder X-ray diffractometer (PXRD), and fluorescence spectroscopy. Under the optimum conditions, the fluorescence intensity increased with increasing of Al 3+ concentrations in the range of 0.28-500.0 ng mL -1 with LOD (S/N = 3) of 0.09 ng mL -1 . The method was applied for the determination of Al 3+ in natural waters and human serum samples with recoveries % of 97-104% and RSDs % of 2-4%.
