Chitosan　(CS)　micro-porous　membranes　were　prepared　by　blending-phase　inversion　method　using　chitosan　as　film-forming　polymer,　polyethylene　glycol　(PEG)　as　porogen　and　glycerol　as　plasticizer.　Adsorption　experiments　were　conducted　under　varied　Cr(VI)　ions　concentration,　pH　values,　contact　time　and　temperature.　The　results　indicated　that　when　the　ratio　of　chitosan　to　polyethylene　glycol　and　glycerol　was　1:0.5:0.5　at　pH　of　2.79,　the　prepared　CS　membrane　exhibited　the　highest　adsorption　capacity　of　168.41　mg　g(-1)　under　Cr(VI)　ions　concentration　of　100　mg　L-1,　contact　time　of　4　h,　and　membrane　dosage　of　10.0　mg.　Langmuir　and　Freundlich　adsorption　models　were　applied　to　describe　the　equilibrium　isotherms　at　different　Cr(VI)　ions　concentrations.　The　equilibrium　data　was　found　to　be　fitted　well　to　the　Langmuir　isotherm.　Pseudo-first-order　and　pseudo-second-order　kinetics　models　were　used　to　describe　the　membrane　adsorption.
