摘　　要：文章将聚甲基丙烯酸β-羟乙酯接枝到硅胶表面,制备了可重复利用的环境友好复合材料PHEMA/Si O2,研究其对废水中染料日落黄的吸附特性。静态吸附实验结果表明,当吸附时间为10 h,p H值为2.0时,复合材料PHEMA/Si O2对日落黄的最大吸附量可达46.3 mg/g,复合材料对日落黄的吸附主要来自静电相互作用力。When the poly 2-Hydroxyethyl methacrylate （PHEMA） is grafted on the surface of silica gel, the reusable and envi-ronment-friendly composite material PHEMA/SiO2 can be prepared. The effect of PHEMA/SiO2 on the absorption characteristic of sunset yellow in waste water is studied in this paper. Static adsorption experiments show that the composite material PHE- MA/SiO2 has strong adsorption property for sunset yellow due to the electrostatic interaction. When the adsorption time is 10 h and the PH value is 2.0, its maximum adsorption capacity to sunset yellow can reach 46.3 mg/g.
