Abstract

Multi-walled carbon nanotubes (MWNTs) were modified by amidoxime group, characterized by fourier transform infrared spectrometer (FTIR). The adsorption experiments of Pb(Pb) on raw MWNTs and amidoxime group modified MWNTs(AO-MWNTs) were studied under different conditions. Results showed that, the adsorption capacities of Pb on raw MWNTs and AO-MWNTs primarily increased with the increasing pH, adsorption temperature and the initial Pb concentration. Under the condition of pH=7 and temperature was 50 , the adsorption capacities reached the maximum. The adsorption equilibrium of raw-MWNTs on Pb reached balance in about 90min and the AO-MWNTs achieved stable in 60min.The adsorption process of AO-MWNTs could be better described by Freundlich model.
