Preparation of Carbon Nanotubes/Activated Carbon Composite Microspheres and Their Application to Adsorption of VB12
Abstract:
Novel carbon nanotubes/activated carbon (CNTs/AC) composite microspheres were prepared by inverse emulsion polymerization, carbonization, and activation, and were applied to the adsorption of VB12, a representative of middle molecular weight toxins found in the human body. Results show that CNTs/AC composite microspheres with 70%(w) CNTs have od sphericity and their adsorption of VB12 reaches 23.59 mg·g-1, which is 5.4 and 2.7 times as much as that of activated carbon and macroporous resin, respectively. This is attributed to the more developed mesopores found in the microspheres.
