巯基功能化介孔二氧化硅的吸附性能

描述了巯基功能化介孔硅酸盐MCM-41和SBA-15的合成及其物理化学特性。研究了该材料对贵金属离子的吸附性能，特别是对盐酸溶液中钯离子的吸附性能。所得到的材料在功能化前后用物理和化学的复合方法进行了表征。对所获得的吸附剂对Pd(II)离子的吸附能力进行了评价。实验结果表明，巯基功能化介孔二氧化硅具有较高的吸附活性/*类型定义*/表。MsoNormalTable {mso-style-name:“Обычнаятаблица”;mso-tstyle-rowband-size: 0;mso-tstyle-colband-size: 0;mso-style-noshow:是的;mso-style-priority: 99;mso-style-qformat:是的;mso-style-parent:“”;Mso-padding-alt:0cm 5.4pt;mso-para-margin: 0厘米;mso-para-margin-bottom: .0001pt;mso-pagination: widow-orphan;字体大小:11.0分;字体类型:“Calibri”、“无衬线”;mso-ascii-font-family: Calibri;mso-ascii-theme-font: minor-latin;mso-fareast-font-family:宋体;mso-fareast-theme-font: minor-fareast;mso-hansi-font-family: Calibri;mso-hansi-theme-font: minor-latin;mso-bidi-font-family:宋体;mso-bidi-theme-font: minor-bidi;}
