中文摘要： 近年来，药品和个人护理品（PPCPs）在饮用水中被频繁检出，由于其具有难降解性、生物累积性和长期危害性，已成为威胁人体健康的巨大隐患。本研究拟针对吸附法处理饮用水中PPCPs时面临的吸附剂成本昂贵、环境适应性差、吸附效率低、脱附再生能力差等实际问题，以饮用水中存在的典型PPCPs（磺胺甲恶唑、双氯芬酸、阿替洛尔）为研究对象，利用吡咯单体在火山岩表面聚合形成聚吡咯导电薄膜，制备聚吡咯负载火山岩复合材料。复合材料兼具电化学特性和吸附特性，不仅可大幅增加有效吸附位点，提高吸附效率，还可通过电场作用强化吸附、脱附与再生过程。研究将结合多种微观表征手段，研究火山岩理化性质对导电薄膜形成的影响机制、火山岩与聚吡咯的协同效应及掺杂离子和反应条件的选择机制，分析复合材料吸附去除饮用水中典型PPCPs的特性和机理，从而为导电聚合物负载型吸附剂的开发及在饮用水深度处理方面的实际应用和优化运行提供理论参考。

英文摘要： Recently, Pharmaceutical and Personal Care Products (PPCPs) are frequently detected from drinking water. The persistent, bioaccumulative and long-term harmful properties make PPCPs a great threat to human health. High cost, low environmental adaptability, limited adsorption ability, and poor desorption-regeneration performance are the shortcomings of adsorption methods in the treatment of PPCPs from drinking water. This study aims to prepare polypyrrole/volcanics (PPy/VCN) composite to remove typical PPCPs (sulfamethoxazole, diclofenac and atenolol). The electroconductibility and adsorptivity of PPy/VCN can greatly increase effective adsorption sites and consequently improve the adsorption efficiency of PPCPs. Moreover, adsorption, desorption and regeneration processes can be enhanced by introducing electric field. Influencing mechanism of physicochemical property of volcanics on the formation of electroconductive film, synergistic effect between PPy and VCN, and the selection of doping ion and reaction conditions will be investigated by using varieties of characterization methods. The analysis of adsorption property and mechanism on typical PPCPs removal will be discussed in details. This study will contribute to the development of conducting polymer doping adsorbents and their application and optimization in the field of advanced treatment of drinking water.
