| 摘 要： | 通过季铵盐改性四钛酸钾晶须,应用X射线衍射分析、红外光谱,紫外-可见漫反射光谱对改性前后的四钛酸钾晶须进行表征,并初步研究了不同季铵盐改性的四钛酸钾晶须对苯酚吸附性能的研究。实验结果表明,改性前后的四钛酸钾晶须在紫外光区均有较强的光吸收,而在可见光区其吸收则较弱。改性前后四钛酸钾晶须的结构没有改变,季铵盐能够进入层状化合物的层板间,使改性后的层间距稍微增大。与改性前相比,改性后的四钛酸钾晶须对苯酚的吸附量和吸附率有了明显的提高。

| Abstract: | Potassium tetratitanate whisher(PTW) modified with quaternary ammonium salt(QAS) were investigated.The modified PTW were characterized by IR,X-ray spectroscopy,UV-Vis DRS,and adsorption properties of the different of PTW modified with QAS on phenol were preliminary study.Before and after modifying,K2Ti4O9 whiskers had the strong light absorption in ultraviolet light,but the weak in visible light.The structures of PTW had no change before and after modifying,and the QAS was inserted into the interlayer of PT... |
