A new type of surface ion-imprinted polymer was synthesized in aqueousmedia with sodium trititanate whisker in the presence of Cd(Ⅱ), chitosan and γ-glycidoxypropyl trimethoxysilane (KH-560). A batch of adsorption experimentswere performed to evaluate its adsorption of Cd(Ⅱ) using inductively coupledplasma atomic emission spectrometry (ICP-AES). The factors affecting adsorptioncapacity, including pH and sorbent amount, were discussed. The adsorptionkinetics and adsorption isothermals were also obtained. The Langmuir isotherm canfit in the experimental equilibrium data. Under the optimum conditions, the valueof the adsorption was above 99 %, and the maximum adsorption capacity was 52.34mg?g-1. In accordance with the parameters distribution coefficient (Kd) andselectivity coefficient (K), the selectivity for Cd(Ⅱ) of the prepared imprintedpolymer was estimated. Finally, the adsorption mechanism was discussed and thedetection limit of 0.024 μg?mL-1 with the relative standard deviation (RSD) of1.74% (ｃ=1.0 μg?mL-1, n=13) for Cd(Ⅱ) was obtained. Results showed that thesurface Cd(Ⅱ)-imprinted polymer was a solid sorbent with high efficiency, low-cost, convenient separation/enrichment for environmental trace Cd(Ⅱ).spectrometry; Adsorption; Cadmium (Cd(Ⅱ))学技术基金项目(05C26213100474)资助
