摘要

摘要:本研究开发了一种新型的酚醛泡沫树脂吸附剂，用于提取稀土元素。以苯酚、儿茶酚或间苯二酚为交联剂，在甲醛存在下，以苯酚、儿茶酚或间苯二酚的混合物为预聚物，通过适当的发泡剂、表面活性剂、固化酸剂和苯酚二醇酰胺衍生物的碱性聚合反应制备了螯合酚醛泡沫。完整地描述了泡沫共聚物树脂，并对三种镧系元素(La, Eu, Yb)进行了吸附研究，这三种镧系元素分别代表轻、中、重稀土。

Diglycolamide phenolic foams as sorbent for rare earth elements

ABSTRACT In this present study, we developed a new series of sorbents based on phenolic foam resin for the extraction of rare earth elements. Chelating phenolic foams were prepared using appropriate formulation of blowing agent, surfactant and curing acid agent and a prepolymer resulting from an alkaline polymerisation reaction of phenolic diglycolamide derivative with admixture of phenol, catechol or resorcinol in the presence of formaldehyde as crosslinker agent. The foaming copolymer resins were completely described and engaged in sorption studies with three types of lanthanide (La, Eu, Yb), which represent light, medium and heavy REEs, respectively.

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
