Carboxymethyl　chitosan　(CMCS)　grafted　with　β-cyclodextrin　(CMCS-g-CD)　modified　silica　gel　as　a　new　solid　phase　extraction　(SPE)　adsorbent　for　cadmium　has　been　developed.　The　optimum　batch　experimental　conditions　(pH,　amount　of　adsorbent　and　contact　time)　and　column　experimental　conditions　(concentration　and　volume　of　elution　solution)　were　optimized,　respectively.　The　kinetic　models　for　Cd　(II)　were　investigated　and　the　results　indicated　that　pseudo-second-order　equation　provided　a　better　R2　(R2>0.999)　and　agreement　between　calculated　Qe　value　(10.6mg/g)　and　the　experimental　Qe　(exp)　value　(11.3mg/g).　The　developed　method　was　successfully　applied　to　the　determination　of　Cd(II)　in　lake　water　and　tap　water　with　recoveries　ranging　from　96.0%　to　102.0%.　©　2013　Elsevier　B.V.
