Molecular sieve doped magnetic carbon nanotube composite material, and preparation method and applications thereof

The invention belongs to the field of nanometer material, and discloses a molecular sieve doped magnetic carbon nanotube composite material, and a preparation method and applications thereof. The molecular sieve doped magnetic carbon nanotube composite material is magnetic carbon nanotube obtained through loading carbon nanotube with magnetic iron oxides and CaCO3, and doping of a molecular sieveonto the magnetic carbon nanotube. The molecular sieve doped magnetic carbon nanotube composite material possesses relatively high removing rate on ammonia nitrogen in water; ammonia nitrogen removingrate in 30min of adsorption is capable of reaching 80% or higher, in 45min of adsorption is capable of reaching 90% or higher; loading of the magnetic iron oxides is capable of providing the obtainedcomposite material with magnetic performance, rapid separation recycling from water can be realized through magnetic separation, regeneration can be realized using NaOH+NaCl solution, and the regeneration rate is as high as 10
