Abstract

The invention discloses zirconium-based metal organic frameworks UiO-66 and application thereof, and further discloses a preparation method. The preparation method comprises the steps that zirconium tetrachloride and acetic acid are dissolved in N, N-dimethylformamide, terephthalic acid is added, and uniform stirring is carried out so as to obtain a mixed reaction solution; and the mixed reactionsolution is transferred into a reaction kettle and is placed at the temperature of 120 DEG C for reaction for 7-24 hours, then cooling is carried out to reach room temperature, solid-liquid separationis carried out, and then solid obtained after solid-liquid separation is cleaned and dried so as to obtain the zirconium-based metal organic frameworks UiO-66. The zirconium-based metal organic frameworks UiO-66 can serve as a liquid binding phase of a DGT(diffusive gradients in thin-films) device and are used for measuring the active phosphorus of a water body; and the zirconium-based metal organic frameworks UiO-66 have good binding capacity for the phosphorus and can be applied to the DGT(diffusive gradients in thin-films) device as the liquid binding phase, so that in-situ collection andrapid detection can be carried out on the active phosphorus of the water body, in addition, the operation is simple, the accuracy is high, the stability is good, and the the zirconium-based metal organic frameworks UiO-66 are suitable for long-term storage and large-scale production.

Description

technical field

[0001] The invention relates to the field of zirconium-based metal organic framework materials, in particular to a zirconium-based metal organic framework material UiO-66 and its application. Background technique

[0002] Phosphorus is the most important source of primary productivity and food chain, and it is also an important limiting nutrient for the outbreak of cyanobacteria blooms in water bodies. Accurate and reliable monitoring of active phosphorus in water bodies is of great significance for early warning of eutrophication in water bodies and control of cyanobacteria blooms. For a long time, the detection of active phosphorus concentration in water mainly adopts active sampling technology, but what it obtains is only the concentration level of phosphorus at the moment of sampling, and cannot represent the actual pollution level of phosphorus in a period of time, which makes active sampling very random. Therefore, the development of in-situ passive sam...
