多壁碳纳米管的对氨基苯磺酸钠修饰及对Cu2+的吸附性能
Modification of carbon nanotubes with sodium p-aminobenzenesulfonate and its effect on Cu2+ adsorption
摘要
Abstract
Multiwalled carbon nanotubes (MWCNTs) were oxidized by concentrate HNO3 and then reacted with SOC12 to form MWCNT-COC1. Water-soluble sodium p-aminobenzenesulfonate-grafted multiwalled carbon nanotubes ( MWCNT-CO-NHC6H5SO3Na) were synthesized by an amidation reaction of sodium p-aminobenzenesulfonate with MWCNT-COC1, which was verified by FT-IR spectroscopy. The content of the sodium p-aminobenzenesulfonate grafted onto the MWCNT surface reached 29. 9 mass%. The MWCNT-CO-NHC6H5SO3Na showed a good solubility and dispersion in water, and had an improved adsorptive performance for the removal of low concentrations of Cu2+ in water. The adsorption isotherms of the MWCNT-CO-NHC6H5SO3Na for Cu2+ can be well fitted by the Freundlich equation.关键词
