聚合物刷型二齿硼酸配体吸附剂的制备及其对尿液中核苷的分离富集性能分析OA北大核心CSTPCD
Preparation of Polymer Brushes with Diboronic Acid Ligand for Separation and Enrichment of Nucleosides in Human Urine
为提高硼亲和吸附剂的结合力和吸附容量,以丙烯酰胺为单体,通过原子转移自由基聚合反应在聚多巴胺磁性微球(Fe3O4@pDA)表面接枝富含氨基的聚合物刷,然后键合二齿硼酸配体,获得聚合物刷型二齿硼酸配体吸附剂(Fe3O4@pDA@p-DBA).利用红外光谱和X-射线光电子能谱对材料进行表征,并研究了材料的吸附性能.结果表明,吸附剂对顺式二羟基化合物具有较高的选择性,并且二齿硼酸配体吸附剂较单齿硼酸配体吸附剂(Fe3O4@pDA@p-BA)具有更高的亲…查看全部>>
To improve the binding strength and adsorption capacity,a boronate affinity adsorbent was prepared by atom transfer radical polymerization using acrylamide as monomer,and then decorated with a bidentate boronate ligand(DBA)by post-modification.The materials were characterized by infrared spectrum and X-ray photoelectron spectroscopy,and the adsorption properties of the materials were studied.The results showed that the adsorbent had higher selectivity …查看全部>>
