Mxenes is a kind of inorganic 2D dimensional nano materials with novel structure. It is composed of transition metal carbides, nitrides or carbonitrides with several atomic layers. At present, mxenes are widely used in the fields of energy, optics, catalysis, adsorption and so on. Because of its high hydrophilicity, large specific surface area, negative surface charge and high ion exchange capacity, it is used as an excellent adsorbent material. Mxenes materials will remove heavy metal ions and radioactive elements in the environment through electrostatic attraction, coordination chelation and other interactions.
It is expected to become an ideal carrier for adsorbing heavy metal ions and radioactive. In this experiment, the property of adsorption of MXene is used. It is used to modified the surface of a cotton to make a filter cloth. There are also another liquids used in this experiment to modify the surface of the filter cloth which have some useful functional group. While the MXene play the most important role in this experiment. By using immersing method, the end product shows it is play a role in purify mythlene blue liquid. Besides, even though there is some other pollutes in waste water of industry, MXene is a good adsorbent to absorb other heavy metal ions in terms of in this experiment only the adsorption of dyestuff has been tested.
