Abstract Molecularly imprinted polymers (MIPs) of melamine (MEL) were synthesized by non-covalent approach with precipitation polymerization. In this research, MEL was used as the template molecule, acrylamide (AAm) as the functional monomer, divinylbenzene (DVB) as the cross-linker, 2,2′-azobisisobutyronitrile (AIBN) as an initiator, and the mixture of dimethyl sulfoxide (DMSO) and acetonitrile (ACN) was used as a reaction medium. The imprinted and non-imprinted polymer particles were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), and thermogravimetric analysis (TGA). The rebinding efficiency was evaluated for all the synthesized polymers by batch binding analysis. The adsorption studies such as adsorbent dosage of polymer, initial concentrations, and pH of MEL solution were successfully conducted on the selected polymer. For selectivity test, 2,4,6-trichlorophenol (2,4,6-TCP) was selected as competitive molecule against the MEL. A good removal efficiency of MEL from different samples such as milk (81.97%), river water (91.52%), and human blood serum (90.66%) was achieved. GRAPHICAL ABSTRACT

用于从加标牛奶、水和血清中提取三聚氰胺的分子印迹聚合物的合成、表征和应用

摘要 采用非共价方法和沉淀聚合法合成了三聚氰胺（MEL）分子印迹聚合物（MIPs）。本研究以MEL为模板分子，丙烯酰胺（AAm）为功能单体，二乙烯基苯（DVB）为交联剂，2,2'-偶氮二异丁腈（AIBN）为引发剂，二甲基亚砜的混合物(DMSO) 和乙腈 (ACN) 用作反应介质。通过傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、Brunauer-Emmett-Teller（BET）和热重分析（TGA）对印迹和非印迹聚合物颗粒进行表征。通过分批结合分析评估所有合成聚合物的再结合效率。吸附研究，如聚合物的吸附剂用量、初始浓度、MEL 溶液的 pH 值和 pH 值已成功地用于选定的聚合物。对于选择性测试，选择 2,4,6-三氯苯酚 (2,4,6-TCP) 作为对抗 MEL 的竞争分子。对牛奶 (81.97%)、河水 (91.52%) 和人血清 (90.66%) 等不同样品中的 MEL 实现了良好的去除效率。图形概要
