| 摘 要： | 本文研究了０．２Ｍ ＮａＣｌ水溶液中亚甲兰,亮绿,中性红,品红和孔雀石绿在甲基（苯乙基）键合硅胶上的吸附速率曲线和等温线,结果表明,５种有机染料分子在键合硅胶上的平衡时间小于１ｈ,其吸附等温线符合改进ＢＥＴ方程,而且推测其吸附过程是一个开始在键合硅胶表面发生单分子层吸附,然后在微孔“凝聚”的过程。

| Abstract: | qbsorption speed and absorbed amount are studbed for the adsorption of 5organic dyes (methylene blue, light green, intrazan red, basic violet and astralon green) on methyl (phenylethyl) bonded silica gel in aqueous solutions with 0.2M NaCl. The experimental results indicate that the 5 studied dyes reach adsorption epuilibrium ill less than 1 hour on the bonded silica gel, the isotherms fit the modified BET equation, supposing that the adsorption is a process in which the monomolecular layer adsorption on the surface takes plaee first, and then occurs "coacervation" in the micro-holes of the bonded silica gel |
