新型甲醛吸附剂的制备及性能表征

Preparation and performance of a new formaldehyde adsorbent

在过氧化苯甲酰引发作用下,将聚酰胺进行处理得到表面改性的接枝种子微粒与模板分子甲醛、功能单体丙烯酸甲酯、交联剂EGDMA等进行聚合反应,制备甲醛分子印迹聚合物。利用红外光谱对分子印迹聚合物进行表征,利用静态和动态平衡吸附法研究印迹聚合物的吸附特征,并与活性炭进行比较。结果表明:与活性炭相比,该印迹化合物吸附量更高,为26.3 mg/g,且可再生重复使用。

A molecularly imprinted polymer of formaldehyde（ FMH-MIP） is prepared by conducting the polymerizationof surface modified polyamide,formaldehyde,functional acrylate monomers and crosslinker EGDMA,with benzoyl peroxide as initiator. The structure of FMH-MIP is characterized by infrared spectroscopy. The adsorption properties of FMH-MIP are studied by the static and dynamic equilibrium adsorption method,using acticarbon as control.The results show that FMH-MIP not only has high formaldehyde adsorption capacity（ 26. 3 mg / g） but also is renewable and reusable.
