摘要:以Pb2+為模板，殼聚糖為單體，硅膠為載體，γ-(2,3環氧丙氧)丙基三甲氧基硅烷(KH-560)為偶聯劑，利用表面分子印跡技術和溶膠。凝膠法制備Pb2+印跡聚合物。通過Pb2+的濃度，pH值，靜置時間等因素對分子印跡聚合物的吸附效果影響進行相應的研究，結果表明，吸附酸度pH=3.5時，30mg吸附劑吸附的5h達到平衡，Pb2+離子印跡聚合物具有較好的選擇性，同時具有良好的脫附性能，用2mol/L鹽酸中達到重金屬離子解吸，效果不錯。利用制得的印跡聚合物和非印跡聚合物，檢測對環境中鉛離子的吸附性能表明，吸附率良好。

Abstract:Plumbum as a template, and Chitosan as monomers, silica gel as the carrier, gamma-(2, 3 epoxy propyl ether) propyl trimethoxy silane (KH-560) for coupling agents, use of surface molecular imprinted technique and Sol. Preparation of plumbum imprinted polymer by gel. By plumbum concentration, pH value, standing time and other factors on the adsorption effect of molecular imprinted polymer of corresponding studies, showed that adsorption of pH when pH value is 3.5, 30mg 5h balance of the adsorbent, Pb2+ ion selectivity of molecularly imprinted polymer has better, and with excellent desorption properties, with 2 mol/L up to heavy metal ions in hydrochloric acid desorption, works well. Molecularly imprinted polymer and produced using non-imprinted polymer, lead ion adsorption property of testing on the environment shows that absorption rate is good.
