effect of humic acids on physicochemical property and cd ii sorption of multiwalled carbon nanotubes
Chemosphere, 2012Co-Authors: Xiaoli Tian, Tingting Li, Yuedong Xu, Kun Yang, Huifeng LuAbstract:Carbon nanotubes (CNTs), as a type of superior adsorbents for both organic and inorganic contaminants, are Increasingly introduced into the environment. Ubiquitous natural organic matter (NOM) would coat on the released CNTs and change their physicochemical properties and sorption of contaminants. The effects of four sequentially extracted humic acids (HAs, as a model NOM) from a peat soil on the physicochemical properties and Cd(II) sorption of three multiwalled CNTs (MWNTs) with different Surface Areas were investigated. The MWNTs as purchased with very few oxygen-containing functional groups had relatively low sorption capacities (0.93-1.49 mg g(-1)) for Cd(II) and the sorption capacity increased with Increasing Surface Area of the MWNTs. Surface-coating with the HAs lowered Surface Areas of the MWNTs but greatly increased their sorption capacities (5.42-18.4 mg g(-1)). The MWNT-bound HAs introduced oxygen-containing functional groups and negative charges to the MWNT Surfaces, which could thus increase the apparent sorption of Cd(II) through chemical complexation and electrostatic attraction, respectively. The later-extracted HAs with lower polarity were more favorable for the Surface-coating but increased less Cd(II) sorption by the MWNTs. The results are expected to shed light on understanding the underlying mechanism of the effect of NOM on the sorption of heavy metal ions by CNTs.
