Abstract:
It is critical to detect Fe 3+ and Al 3+ rapidly and accurately due to their high risk to humans and the ecological environment. In this work, a kind of terbium-based metal–organic framework fluorescent probe (Tb-MOF) is facilely fabricated that displays ultra-high selective detection of Fe 3+ and Al 3+ over various coexisting ions ( i.e. Mn 2+ , Co 2+ , K + , Ca 2+ , Na + , Mg 2+ , Cd 2+ , Cu 2+ , Fe 2+ , Zn 2+ , Ni 2+ , Pb 2+ and Cr 3+ ). The obtained Tb-MOF exhibits emission at 547 nm and possesses outstanding thermal, fluorescent and chemical stability. The Tb-MOF shows a ratiometric fluorescence signal for Al 3+ , and the detection limits for Fe 3+ and Al 3+ are 0.91 and 6.10 μM, respectively. Moreover, the fluorescence intensities and concentrations of Fe 3+ and Al 3+ have good linear relationships across wide concentration ranges. Furthermore, the quantifications of Fe 3+ and Al 3+ are achieved in complex tap and river water samples with good recoveries. This study offers a facile and efficient method of developing a fluorescent probe that possesses the ability to quantify Fe 3+ and Al 3+ in real environmental water samples.
