We　prepared　alginate-chitosan　(ALG-CTS)　complexes　through　ionic　interaction,　and　then　obtained　Cu　(II)-imprinted　alginate-chitosan　complex　microspheres　(Cu-ALG-CTS)　by　coupling　with　ionic　imprinting　technology.　To　investigate　the　effects　of　experimental　conditions　on　adsorption　behavior,　we　performed　a　series　of　experiments　including　changing　the　initial　concentration　of　Cu　(II)　ions　and　adsorption　time.　We　found　that　the　adsorption　capacity　increases　with　the　initial　concentration　of　Cu　(II)　ions.　The　Cu　(II)　ions　adsorption　reaches　the　maximum　of　70.54mg/g　after　adsorbing　for　13h　when　the　initial　concentration　of　Cu　(II)　ions　is　60　mu　g/ml.　Cu-ALG-CTS　shows　much　higher　adsorption　for　Cu　(II)　ions　than　Zn　(II)　ions.　And　the　adsorption　kinetics　and　equilibrium　adsorption　isotherm　were　further　studied.
