Sodium dodecyl benzene sulfonate for single-walled carbon nanotubes separation in gel chromatography

Though sodium dodecyl benzene sulfonate (SDBS) exhibited stronger dispersing ability for single-walled carbon nanotubes (SWCNTs) in comparison to sodium dodecyl sulfate (SDS). SDBS was not reported to be successfully employed in SWCNTs separation. In this work, we report that SDBS dispersed SWCNTs can be loaded onto Sephacryl gel S200 and these retained SWCNTs can be selectively eluted out using SDBS eluent with various concentrations and its mixture composition with SDS.
