A　cadmium(II)-imprinted　polymer　was　synthesized　by　imprinting　technique　using　Cd(II)　as　the　template　and　carboxymethyl　chitosan　(CMCS)　as　the　functional　monomer.　The　prepared　polymer　was　characterized　by　FT-IR,　X-ray　diffraction　(XRD)　and　thermogravimetry　(TG).　The　diffraction　peaks　of　cadmium(II)-imprinted　adsorbent　become　weaker　and　wider　than　those　of　carboxymethyl　chitosan,　and　the　thermal　stability　of　adsorbent　bonded　silica　gel　is　better　than　that　of　carboxymethyl　chitosan.　The　uptake　behavior　of　Cd(II)　ions　onto　this　sorbent　was　evaluated.　The　kinetic　data　can　be　fitted　to　the　pseudo-second　order　equation.　Adsorption　process　can　be　well　described　by　Langmuir　adsorption　isotherms.　The　recoveries　of　water　samples　are　about　98.0%~104.0%.
