yield a water‐soluble polymer or a cross‐linked network as a powder or a dense membrane. In powder form, the material selectively removed Hg2+, Pb2+, and Ag+ from aqueous media. In the form of swelled dense membranes or films, the material acted as colorimetric sensor for Fe3+. When the membrane was soaked in a yellow aqueous solution of Fe3+, the former colorless, transparent membrane became reddish (but
制备了具有凝胶性质的线性水溶性聚合物和网,用作比色传感器和选择性萃取剂,用于肉眼检测和从水性环境中固液去除重金属阳离子。三唑是著名的重金属阳离子主体。将包含1,2,4-三唑受体衍生物的不溶于水的甲基丙烯酰胺与高度亲水和水溶性的甲基丙烯酰胺共聚,生成水溶性聚合物或交联网络,形成粉末或致密膜。以粉末形式,该材料从水性介质中选择性去除Hg 2 +,Pb 2+和Ag +。该材料以膨胀的致密膜或薄膜的形式充当Fe 3+的比色传感器。当将膜浸入黄色的Fe 3+水溶液中时,原来的无色透明膜发红(但保持其透明性),溶液变为无色。水电导率研究证实,萃取和感测现象均源于阳离子与三唑部分的相互作用。©2011 Wiley Periodicals,Inc.
