Al(OH)3　modified　nickel　slag　adsorbent　was　prepared　by　sintering　technology.　The　structure　of　the　sample　was　characterized　by　BET,　XRD,　IR,　SEM　and　EDAX.　The　sample＇s　adsorption　performance　of　Pb2+　and　Cu2+　from　aqueous　solution　was　studied.　Results　indicated　that　the　adsorbent　is　a　loose　and　porous　mesoporous　material.　Its　surface　had　mass　aluminosilicate,　high-activity　γ-Al2O3　and　its　pH　ranges　from　4　to　12　that　all　have　negative　charges.　The　BET　surface　of　the　adsorbent　is　23.90　m2/g.　Furthermore,　its　surface　contains　rich　oxygenic　functional　groups,　which　could　not　only　provide　abundant　adsorption　sites　for　Pb2+　and　Cu2+,　but　also　improve　the　adsorption　performance　of　Pb2+　and　Cu2+　from　waste　water　through　the　complexation　of　heavy　metal　ions.　The　best　pH　values　selected　in　the　adsorption　of　Pb2+　and　Cu2+　are　6　and　5,　respectively.　With　the　increase　of　the　initial　concentration　of　simulated　solution,　the　adsorption　capacities　of　Pb2+　and　Cu2+　gradually　increased　but　the　removal　rates　showed　a　downward　trend.　The　competitive　adsorption　results　of　Pb2+　and　Cu2+　showed　that　Pb2+　has　better　preferential　adsorption　than　Cu2+.
