Abstract：

The　selective　adsorption　of　Cr6+,　Ni2+　and　static　absorption　of　Cr6+　and　Ni2+　on　a　novel　spherical　chelating　cellulose　adsorbent　(SCCA)　containing　carboxyl　and　imidazolyl　groups　were　studied.　The　results　showed　that　SCCA　has　good　adsorption　performance　for　Cr6+,　and　follows　the　relation　of　Langmuir　adsorption　isotherm　formula.　The　adsorption　capacity　increases　with　an　increase　of　solution　temperature.　The　saturation　adsorption　capacity　for　Cr6+　is　53.48　mg/g　under　the　optimum　conditions　(60°C　of　adsorption　temperature,　2　hours　of　adsorption　time,　1　of　solution　pH).　SCCA　has　bad　adsorption　performance　for　Ni2+,　and　it　follows　the　relation　of　Langmuir　and　Freudlich　adsorption　isotherm　formulas.　The　adsorption　processes　of　Cr6+　and　Ni2+　are　controlled　both　by　models　of　surface　diffusion　process　and　intraparticle　diffusion　process　in　early-time.　SCCA　has　good　adsorption　selectivity　for　Cr6+　when　Cr6+　and　Ni2+　are　in　coexistence.　The　adsorption　selectivity　parameter　is　26.38　under　the　solution　pH　value　1　and　the　adsorption　temperature　60°C.
