The present disclosure is directed to polymeric beads, methods of making the beads, and methods of using the beads as high-capacity anion exchange materials. In particular, the disclosure provides polymeric beads comprising a cross-linked polyamine and having a crush strength of about 250 g/bead or more. Preferably, the beads are substantially spherical. Also disclosed are polymeric beads comprising a cross-linked polyamine that has a substantial number of both strong base sites and weak base sites. Methods of using the polymeric beads in various industrial applications, such as groundwater remediation, radio waste management, municipal wastewater management, demineralization, toxin removal, mining, food refinery, research, agriculture, and the like, are also disclosed herein.
本公开涉及聚合物微珠、制备该微珠的方法,以及将该微珠用作高容量阴离子交换材料的方法。具体而言,本公开提供了交联聚胺制备的聚合物微珠,其破碎强度为每颗珠子约250克或更高。最好,该微珠是近乎球形的。本公开还揭示了交联聚胺制备的聚合物微珠,其拥有大量强碱性和弱碱性位点。本公开还揭示了在各种工业应用中使用聚合物微珠的方法,例如地下水修复、放射性废物管理、市政废水管理、脱矿化、毒素去除、采矿、食品精炼、研究、农业等。
