Abstract：

A　porous　Si-Ca　composite　adsorbent　was　prepared　by　using　oyster　shell　and　silicon　powder　as　raw　materials　following　calcining　and　hydrothermal　process,　and　its　microstructure　and　properties　were　characterized.　Single　and　binary　solute　adsorption　of　Pb2+　and　Cu2+　were　performed　by　batch　tests.　The　influences　of　initial　pH,　initial　ion　concentration,　and　time　on　competitive　adsorption　were　discussed.　The　results　show　that　the　suitable　pH　for　competitive　adsorption　is　5.0.　The　maximum　adsorption　capacities　for　single　ion　are　0.87　mg/g　for　Cu2+　and　0.71　mg/g　for　Pb2+.　The　competitive　adsorption　results　show　that　the　affinity　order　of　two　metal　ions　by　the　adsorbent　is　Cu2+>　Pb2+.　The　adsorption　mechanism　is　mainly　physical　adsorption.　©　2016,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
