| 摘 要： | 采用悬浮聚合、炭化、活化制得碳纳米管/活性炭复合微球; 而后利用重氮盐偶合法将对氨基苯磺酸接枝到此复合微球上, 得到磺化碳纳米管/活性炭复合微球; 将其用于吸附血清中的低密度脂蛋白(LDL). 结果表明: 所制备的磺化碳纳米管/活性炭复合微球球形度好, 表面光洁, 中孔发达, 并且接枝有对氨基苯磺酸. 此复合微球对LDL的吸附量随着碳纳米管加入量的增加而逐渐增大; 当碳纳米管加入量为45% (w)时, LDL吸附量达6.564 mg·g-1, 是未添加碳纳米管的3.3倍. 此复合微球在作为血液灌流LDL吸附剂方面有较好的应用前景.

| Abstract: | Sulfonated carbon nanotubes (CNTs)/activated carbon composite beads were obtained by suspension polymerization,carbonization,activation,and further sulfonation using the diazonium salt coupling method.Adsorption of low density lipoprotein (LDL) was explored with these composite beads.The results showed that the composite beads had good sphericity,smooth surface,developed mesopores and were sulfonated by p-aminobenzenesulfonic acid.With the increase of CNTs mass ratio,the adsorption capacity of LDL increased... |
