This work systematically investigated the effects of prepolymerization on the property of multi-templates surface molecularly imprinted polymer (MIP), which was utilized to quickly and simultaneously separate and detect six sulfonamides (sulfadiazine, sulfathiazole, sulfamerazine, sulfamethazine, sulfamethoxazole and sulfadoxine) in real waters. The MIPs were prepared using the six sulfonamides as the templates, mesoporous silica supported onto the surface of magnetic graphene oxide as the carrier and 4-vinylbenzoic as the functional monomer, with and without prepolymerization of templates with functional monomer. The preparation and adsorption conditions were optimized. It was found that the adsorption capacities of the selected six sulfonamides on the MIP (pre) prepared with prepolymerization were apparently higher than those on the MIP (no pre) synthesized without prepolymerization. Subsequently, the MIPs were utilized as adsorbents for SPE of these sulfonamides, and coupled with high performance liquid chromatography (HPLC) for the determination of sulfonamides. The developed analytical method showed outstanding applicability for the detection of trace sulfonamides in real water samples. The spiked recoveries and relative standard deviations (RSDs) of the six sulfonamides using MIP (no pre) and MIP (pre) were 73.34-99.43% and 87.37-102.34%, 2.28-7.77% and 3.18-6.49%, respectively.

预聚合对表面分子印迹聚合物的影响,用于快速分离和分析水中的磺酰胺。
这项工作系统地研究了预聚合对多模板表面分子印迹聚合物(MIP)性能的影响,该聚合物可用于同时快速分离并检测六种磺酰胺(磺胺嘧啶,磺胺噻唑,磺胺嘧啶,磺胺二甲嘧啶,磺胺甲恶唑和磺胺多辛)水域。使用六种磺酰胺类作为模板,介孔二氧化硅负载在磁性氧化石墨烯的表面上作为载体,以4-乙烯基苯甲酸为功能性单体,在有或没有模板与功能性单体的预聚合下制备MIP。优化了制备条件和吸附条件。发现选择的六种磺酰胺在用预聚合制备的MIP(预)上的吸附能力明显高于在没有预聚合的情况下合成的MIP(无预)。随后,将MIP用作这些磺酰胺的SPE吸附剂,并与高效液相色谱(HPLC)结合使用以确定磺酰胺。发达的分析方法在实际水样中痕量磺酰胺的检测中具有出色的适用性。使用MIP(无前处理)和MIP(前处理)对六种磺酰胺的加标回收率和相对标准偏差(RSD)分别为73.34-99.43%和87.37-102.34%,2.28-7.77%和3.18-6.49%。并与高效液相色谱法(HPLC)结合用于测定磺酰胺。发达的分析方法在实际水样中痕量磺酰胺的检测中具有出色的适用性。使用MIP(无前处理)和MIP(前处理)对六种磺酰胺的加标回收率和相对标准偏差(RSD)分别为73.34-99.43%和87.37-102.34%,2.28-7.77%和3.18-6.49%。并与高效液相色谱法(HPLC)结合用于测定磺酰胺。发达的分析方法在实际水样中痕量磺酰胺的检测中具有出色的适用性。使用MIP(无前处理)和MIP(前处理)对六种磺酰胺的加标回收率和相对标准偏差(RSD)分别为73.34-99.43%和87.37-102.34%,2.28-7.77%和3.18-6.49%。
