In the present study , the authors examined the adsorption of phenanthrene , 2 - naphthol , and 1 - naphthylamine to three colloidal CNTs , including a stable suspension of oxidized multiwalled carbon nanotubes ( O - MWNT ) , a humic acid ( HA ) - modified colloidal O - MWNT , and a sodium dodecyl sulfate ( SDS ) - modified colloidal O - MWNT .
