Abstract
With the rapid development of aquaculture industry, it is of great significance to monitor the level of multiple related species in water for the sustainable development of the aquaculture industry and the protection of the surrounding ecological environment. In this paper, a novel fluorescent MOF sensor UiO-66-NH2@NDBPA has been developed conveniently based on coordination compensated strategy and applied for simultaneous dual-detection of both phosphate and hydrogen sulfide with non-interference to each other, which are two very important relative species in aquaculture water. The detection limits of phosphate and hydrogen sulfide were as low as 45 nM and 120 nM, respectively. Additionally, the practicability for the simultaneous dual-detection based on this sensor was further proved by the detection of phosphate and hydrogen sulfide in actual water samples and the recovery rate ranged from 98.8% to 103.2%.
