Removal of Middle Molecular Weight Toxins by Carbon Nanotubes
The adsorption properties of middle molecular weight toxins on two types of Carbon Nanotubes (CNTs) (i.e., single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs)) were studied compared with two commercial haemoadsorbents (i.e., activated carbon (AC) and macroporous resin (MR)). Results showed that it took only 10 and 30 min for MWNTs and SWNTs to achieve the adsorption equilibrium. The adsorption amount of SWNTs reached 122 mg.g.1, which was 14.2 and 27.9 times of that of macroporous resin and activated carbon, respectively. Pore structure analyses indicated that the high adsorption efficiency should be attributed to the higher mesopore volumes of CNTs. All of the results implied the great potential applications of CNTs in haemoperfusion.
