| 摘 要： | 采用SiO2纳米粒子结合硅烷化处理对滤纸进行改性,以罗丹明B、苏丹红Ⅰ及苏丹红Ⅳ为模型化合物,考察了改性滤纸在分离特性上的差异,对不同粒径纳米粒子、不同硅烷化试剂及不同展开剂的极性进行比较、优化后发现,在同等展开条件下,经改性纳米粒子修饰后的滤纸分离色素的效果得到明显改善,且纳米粒子越小、烷基碳链越长、硅烷化越完全,则...

| Abstract: | Rhodamine B, Sudan I, and Sudan IV were used as model compounds to investigate the different separation characteristics of filter paper which had been modified by silica nanoparticles and silylation reagents. The effects of different nanoparticles size, carbon chains length of silylation reagents and treated methods on the separation characteristics of modified filter paper has been studied. The results showed that, the paper modified by smaller silica nanoparticles size, longer carbon chains length, owned better separation performance. The modified filter paper has the similar retention behavior with reversed-phase column chromatography. |
