Beschreibung
Zusammenfassung:	The invention discloses a dual-core-shell magnetic microsphere Fe3O4 (at) SiO2 (at) 7MgO. 2B2O3. 7H2O adsorbent, belongs to the technical field of adsorbents, and can overcome the defects that a traditional magnesium borate adsorbent is inconvenient to recycle, has quality loss, is limited in adsorption selectivity and the like. The functionalized Fe3O4 (at) SiO2 (at) 7MgO. 2B2O3. 7H2O-CR is used for removing methylene blue (MB) and Cu (II) in wastewater, so that co-adsorption with good adsorbability to different dyes and metal ions is realized, and the Fe3O4 (at) SiO2 (at) 7MgO. 2B2O3. 7H2O-CR can be used as a promising sewage treatment adsorbent. 一种双核壳磁性微球Fe3O4@SiO2@7MgO·2B2O3·7H2O吸附剂，属于吸附剂技术领域，可解决传统硼酸镁吸附剂回收不方便，质量有损失，吸附选择性受限等缺点，本发明通过外加磁场实现溶剂和样品的分离；使用功能化后的Fe3O4@SiO2@7MgO·2B2O3·7H2O-CR来去除废水中的亚甲基蓝（MB）和Cu(II)，实现了对不同染料和金属离子良好吸附性的共吸附，可作为一种有前景的污水处理吸附剂。
