| 摘 要： | 在交联淀粉存在和弱酸性条件下,使硅酸钠水解生成的二氧化硅与淀粉复合制备了二氧化硅交联淀粉( Sist),通过FT-IR光谱对材料进行了表征,表明反应中形成的二氧化硅与淀粉发生了交联,形成了无机有机复合材料.进一步研究了其对三种不同类型染料的吸附性能.结果表明当硅酸钠添加量为8％时所得的Sist复合材料对染料的吸附性能最...

| Abstract: | In the presence of cross-linked starch and acidic condition,sodium silicate was hydrolyzed producing the silicon dioxide which further reacted with the starch to obtain silicon dioxide hybrid cross-linked starch(Sist).The Sist was characterized by FT-IR spectrum and it was used to remove the dyes from aqueous solution.The adsorption properties to three types of dyes were studied.Results indicated that the superior adsorption performance for 3 dyes was obtained when 8% of sodium silicate was used in preparat... |
