Abstract

The invention discloses a method for preparing a Ni-MOF adsorbing material by an ultrasonic assisted solvent-thermal method and an application of the Ni-MOF adsorbing material, and relates to the technical field of preparation of heavy metal ion treatment agents. The method comprises the steps: firstly, measuring DMF and EtOH as solvents, weighing terephthalic acid as an organic ligand, and takingNi(NO3)2.6H2O as coordination metal ions; adding acetic acid and benzoic acid as molecular size regulators; stirring with a magnetic stirrer to completely dissolve, then putting in an ultrasonic instrument, carrying out ultrasonic treatment, and making the drugs dispersed evenly and promoting crystallization; finally, pouring the mixed liquid into a reaction kettle with a polytetrafluoroethyleneinner liner, and carrying out a reaction; and washing to remove unreacted drugs after the reaction is finished. The influence of Ni-MOF synthesized in different proportions between Ni<2+> and the organic ligand terephthalic acid on the removal performance of heavy metal ions is mainly studied. In a water environment, the performance of the Ni-MOF material is not destroyed, and heavy metal ions inwater can be effectively separated.

Description

technical field

[0001] The invention relates to the technical field of preparation of a heavy metal ion treatment agent, in particular to a method and application of an ultrasonic-assisted solvothermal method for preparing a Ni-MOF adsorption material. Background technique

[0002] With the rapid development of global industrialization, more and more people are aware of the harm of environmental pollution to life. In the past ten years, heavy metal pollution in water has seriously affected the quality of life of the people. The incidence of cancer in various regions has increased significantly, which has caused a certain degree of panic to people. It is urgent to solve this problem as soon as possible through scientific and technological means. This has prompted researchers to pay great attention to it. However, the current air pollution is also quite serious, and there are varying degrees of smog in major cities. To a large extent, this is inseparable from the waste gas ge...
