Abstract：

We　studied　the　isothermal　adsorption　of　naphthalene　on　a　viscose-based　activated　carbon　fiber　(VACF)　in　aqueous　solution.　The　adsorption　experimental　data　were　fitted　to　adsorption　equations　such　as　the　Langmuir,　Freundlich,　Dubinin-Radushkevitch(D-R),　Dubinin-Astalov(D-A),　Langmuir-Freundlich(L-F),　and　Redlich-Peterson　(R-P)　equations.　The　effects　of　temperature,　pH,　and　pre-loaded　copper　ions　on　the　VACF　on　the　adsorption　of　naphthalene　were　investigated.　The　fitting　results　show　that　the　micropore　volume　filling　theory　fits　better　than　the　single-layer　adsorption　theory　for　naphthalene　adsorption　onto　VACF.　The　adsorption　of　naphthalene　occurs　spontaneously　between　20　and　40　°　C.　The　adsorption　capacity　of　VACF　for　naphthalene　decreases　significantly　above　30　°　C.　A　new　mechanism　is　proposed　to　explain　why　the　adsorption　capacity　increases　significantly　in　lower　pH　aqueous　solutions.　The　reduction　of　naphthalene　takes　place　on　the　VACF　with　pre-loaded　copper　ions.　©　Editorial　office　of　Acta　Physico-Chimica　Sinica.
